As described in the binding document for the "current-speed" property:
"This should only be present in case a driver has no chance to know the
baud rate of the slave device."
This is not the case for the UART used in K3 devices, the current
baud-rate can be calculated from the registers. Having this property
has the effect of actually skipping the baud-rate setup in some drivers
as it assumes it will already be set to this rate, which may not always
be the case.
It seems this property's purpose was mistaken as selecting the desired
baud-rate, which it does not. It would have been wrong to select that
here anyway as DT is not the place for configuration, especially when
there are already more standard ways to set serial baud-rates.

BeaglePlay SBC[1] has Texas Instrument's WL18xx WiFi chipset[2].
Currently, WLAN_EN is configured as regulator and regulator-always-on.
However, the timing and wlan_en sequencing is not correctly modelled.
This causes the sdio access to fail during runtime-pm power operations
saving or during system suspend/resume/hibernation/freeze operations.
This is because the WLAN_EN line is not deasserted to low '0' to power
down the WiFi. So during restore, the WiFi driver tries to load the FW
without following correct power sequence. WLAN_EN => '1'/assert (high)
to power-up the chipset.
Use mmc-pwrseq-simple to drive TI's WiFi (WL18xx) chipset enable
'WLAN_EN'. mmc-pwrseq-simple provides power sequence flexibility with
support for post power-on and power-off delays.
Typical log signature that indicates this bug is:
wl1271_sdio mmc2:0001:2: sdio write failed (-110)
Followed by possibly a kernel warning (depending on firmware present):
WARNING: CPU: 1 PID: 45 at drivers/net/wireless/ti/wlcore/sdio.c:123 wl12xx_sdio_raw_write+0xe4/0x168 [wlcore_sdio]

In current configuration, wm8904 codec on Dahlia carrier board provides
distorted audio output. This happens due to reference clock is fixed to
25MHz and no FLL is enabled. During playback following parameters are set:

[ 310.276990] wm8904 1-001a: Using 25000000Hz MCLK

Deviation = 1411200 vs 1562500 = 10.721%
Also, LRCLK_RATE is 35, should be 32.

[ 302.450092] wm8904 1-001a: LRCLK_RATE is 32
Deviation = 1536000 vs 1562500 = 1.725%
Enabling wm8904 FLL via providing mclk-fs property to simple-audio-card
configures clocks properly, but also adjusts audio reference clock
(mclk), which in case of TI AM62 should be avoided, as it only
supports 25MHz output [1][2].
This change enables FLL on wm8904 by providing mclk-fs, and drops
audio reference clock out of DAI configuration, which prevents
simple-audio-card to adjust it before every playback [3].

The am642-evm doesn't allow to enable 2 x CPSW3g ports and 2 x ICSSG1 ports
all together, so base k3-am642-evm.dts enables by default 2 x CPSW3g ports
and 1 x ICSSG1 ports, but it is also possible to support 1 x CPSW3g ports
and 2 x ICSSG1 ports configuration.
This patch adds overlay to support 1 x CPSW3g ports and 2 x ICSSG1 ports
configuration:
- Add label name 'mdio_mux_1' for 'mdio-mux-1' node so that the node
'mdio-mux-1' can be disabled in the overlay using the label name.
- disable 2nd CPSW3g port
- update CPSW3g pinmuxes to not use RGMII2
- disable mdio-mux-1 and define mdio-mux-2 to route ICSSG1 MDIO to the
shared DP83869 PHY
- add and enable ICSSG1 RGMII2 pinmuxes
- enable ICSSG1 MII1 port

The J722S is a family of application processors built for Automotive and
Linux Application development. J722S family of SoCs is a superset of the
AM62P SoC family and shares similar memory map, thus the nodes are being
reused from AM62P includes instead of duplicating the definitions.
Some highlights of J722S SoC (in addition to AM62P SoC features) are:
* Two Cortex-R5F for Functional Safety or general-purpose usage and
two C7x floating point vector DSP with Matrix Multiply Accelerator
for deep learning.
* Vision Processing Accelerator (VPAC) with image signal processor
and Depth and Motion Processing Accelerator (DMPAC).
* 7xUARTs, 3xSPI, 5xI2C, 2xUSB2, 2xCAN-FD, 3xMMC and SD, GPMC for
NAND/FPGA connection, OSPI memory controller, 5xMcASP for audio,
4xCSI-RX for Camera, 1 PCIe Gen3 controller, USB3.0 eCAP/eQEP,
ePWM, among other peripherals.
For those interested, more details about this SoC can be found in the
Technical Reference Manual here:

Main differences between the new variant and Advanced PG2:
1. Arduino interface is removed. Instead, an new ASIC is added for
communicating with PLC 1200 signal modules.
2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is
available.
3. DP interface is removed. Instead, to communicate with PLC 1200 signal
modules, a USB 3.0 type B connector is added but the signals are
actually not USB.
4. DDR size is increased to 4 GB.
5. Two sensors are added, one tilt sensor and one light sensor.
The light sensor it not yet added to the DT at this stage as it depends
on to-be-added bindings.

A new variant is to be added which will not have a arduino connector
like the existing ones. Factor out all bits that are specific to this
connector.
The split is not perfect because wkup_gpio0 is defined based on what is
common to all variants having the connector, thus containing also
connector-unrelated information. But this is still cleaner than
replicating this node into all 4 variants.

Set VDD_CORE minimum voltage to 0.75V, TI AM62 can run at either 0.75V
or 0.85V depending on the actual speed grade and on the maximum
configured speed (1.4GHz frequency requires 0.85V).
The actual value is programmed into the PMIC EEPROM during manufacturing
(according to the SOC speed grade) and this ensure that both the voltage
values are valid and therefore the OS will not overwrite the value
programmed into the PMIC.

The devices in the wkup domain are capable of waking up the system from
suspend. We can configure the wkup domain devices in a generic way using
the ti-sysc interconnect target module driver like we have done with the
earlier TI SoCs.
As ti-sysc manages the SYSCONFIG related registers independent of the
child hardware device, the wake-up configuration is also set even if
wkup_uart0 is reserved by sysfw.
The wkup_uart0 device has interconnect target module register mapping like
dra7 wkup uart. There is a 1 MB interconnect target range with one uart IP
block in the target module. The power domain and clock affects the whole
interconnect target module.
Note we change the functional clock name to follow the ti-sysc binding
and use "fck" instead of "fclk".
Also note that we need to disable the target module reset as noted by
Markus. Otherwise the sysfw using wkup_uart0 can get confused on some
devices leading to boot time issues such as mbox timeouts.

the SERDES PCIe x2 personality card.
The daughter card also has a USB 2.0 dual-role port. As the base board
already supports a 2.0 dual-role port, enable the port on the SERDES
card to be a host only port.
This will prevent user confusion as having 2 ports in device mode often
leads to confusion as to which port is bound to the gadget function driver.

VP2 and VP3 are unused video ports and VP3 share the same parent
clock as VP1 causing issue with pixel clock setting for HDMI (VP1).
The current DM firmware does not support changing parent clock if it
is shared by another component. It returns 0 for the determine_rate
query before causing set_rate to set the clock at default maximum of
1.8GHz which is a lot more than the maximum frequency videoports can
support (600MHz) causing SYNC LOST issues.
So remove the parent clocks for unused VPs to avoid conflict.

CAN instances 0 and 1 in the mcu domain are brought on the common
processor board through headers J30 and J31 respectively. Thus, add
their respective transceivers 1 and 2 dt nodes to add support for
these CAN instances.
CAN instance 3 in the main domain is brought on the common
processor board through header J27. The CAN High and Low lines
from the SoC are routed through a mux on the SoM. The select lines need
to be set for the CAN signals to get connected to the transceiver 3 on
the common processor board. Therefore, add transceiver dt nodes to add
support for this CAN instance.

The beagleplay dts was using a bit-bang gpio mdio bus as a work-around
for errata i2329. However since commit d04807b806 ("net: ethernet: ti:
davinci_mdio: Add workaround for errata i2329") the mdio driver itself
already takes care of this errata for effected silicon, which landed
well before the beagleplay dts. So i suspect the reason for the
workaround in upstream was simply due to copying the vendor dts.
Switch the dts to the ti,cpsw-mdio instead so it described the actual
hardware and is consistent with other AM625 based boards

Add multiple device tree nodes in order to support
runtime pinmuxing via debugfs.
All nodes are added to the pinctrl device node,
since they are now belonging to multiple interfaces now.
Note: Pinconf is also handled by debugfs-pinmux. This is possible since
pinconf and pinmux accessing the same 32-Bit register and setting the
function mask to 32-Bit allows writes to the whole register.

DSS irq trigger type is set to IRQ_TYPE_EDGE_RISING in the DT file, but
the TRM says it is level triggered.
For some reason triggering on rising edge results in double the amount
of expected interrupts, e.g. for normal page flipping test the number of
interrupts per second is 2 * fps. It is as if the IRQ triggers on both
edges. There are no other side effects to this issue than slightly
increased CPU & power consumption due to the extra interrupt.
Switching to IRQ_TYPE_LEVEL_HIGH is correct and fixes the issue, so
let's do that.

Two carveout reserved memory nodes each have been added for each of the
R5F remote processor device within both the MCU and MAIN domains for the
TI K3 AM68 SK boards. These nodes are assigned to the respective rproc
device nodes as well. The first region will be used as the DMA pool for
the rproc device, and the second region will furnish the static carveout
regions for the firmware memory.
The current carveout addresses and sizes are defined statically for each
device. The R5F processors do not have an MMU, and as such require the
exact memory used by the firmwares to be set-aside. The firmware images
do not require any RSC_CARVEOUT entries in their resource tables either
to allocate the memory for firmware memory segments.
Note that the R5F1 carveouts are needed only if the R5F cluster is
running in Split (non-LockStep) mode. The reserved memory nodes can be
disabled later on if there is no use-case defined to use the
corresponding
remote processor.

The Display Data Channel (DDC) transactions between an HDMI transmitter
(SIL9022A in this case) and an HDMI monitor, occur at a maximum of
100KHz. That's the maximum supported frequency within DDC standards.
While the SIL9022A can transact with the core at 400KHz, it needs to
drop the frequency to 100KHz when communicating with the monitor,
otherwise, the i2c controller times out and shows warning like this.
[ 985.773431] omap_i2c 20010000.i2c: controller timed out
That feature, however, has not been enabled in the SIL9022 driver.

Prepare for pinctrl-single yaml binding and unify pin group node names.
Let's standardize on pin group node naming ending in -pins. As we don't
necessarily have a SoC specific compatible property for pinctrl-single.
I'd rather not add a pattern match for pins somewhere in the name for all
the users.
Trying to add matches for pins-default will be futile as on the earlier
SoCs we've already seen names like pins-sleep, pins-idle, pins-off and so
on that would need to be matched.
And as the node is a pin group, let's prefer to use naming -pins rather
than -pin as more pins may need to be added to the pin group later on.

The WKUP_PADCONFIG register region in J721S2 has multiple non-addressable
regions, accordingly split the existing wkup_pmx region as follows to avoid
the non-addressable regions and include the rest of valid WKUP_PADCONFIG
registers. Also update references to old nodes with new ones.
wkup_pmx0 -> 13 pins (WKUP_PADCONFIG 0 - 12)
wkup_pmx1 -> 11 pins (WKUP_PADCONFIG 14 - 24)
wkup_pmx2 -> 72 pins (WKUP_PADCONFIG 26 - 97)
wkup_pmx3 -> 1 pin (WKUP_PADCONFIG 100)

There are timer IO pads in the MCU domain, and in the MAIN domain. These
pads can be muxed for the related timers.
There are timer IO control registers for input and output. The registers
for CTRLMMR_TIMER*_CTRL and CTRLMMR_MCU_TIMER*_CTRL are used to control
the input. The registers for CTCTRLMMR_TIMERIO*_CTRL and
CTRLMMR_MCU_TIMERIO*_CTRL the output.
The multiplexing is documented in TRM "5.1.2.3.1.4 Timer IO Muxing Control
Registers" and "5.1.3.3.1.5 Timer IO Muxing Control Registers", and the
CASCADE_EN bit is documented in TRM "12.6.3.1 Timers Overview".
For chaining timers, the timer IO control registers also have a CASCADE_EN
input bit in the CTRLMMR_TIMER*_CTRL in the registers. The CASCADE_EN bit
muxes the previous timer output, or possibly and external TIMER_IO pad
source, to the input clock of the selected timer instance for odd numered
timers. For the even numbered timers, the CASCADE_EN bit does not do
anything. The timer cascade input routing options are shown in TRM
"Figure 12-3224. Timers Overview". For handling beyond multiplexing, the
driver support for timer cascading should be likely be handled via the
clock framework.
The MCU timer controls are also marked as reserved for
usage by the MCU firmware.

There are 20 general purpose timers on j721e that can be used for
things like PWM using pwm-omap-dmtimer driver. There are also
additional ten timers in the MCU domain which are meant for MCU
firmware usage and hence marked reserved by default.
The odd numbered timers have the option of being cascaded to even
timers to create a 64 bit non-atomic counter which is racy in simple
usage, hence the clock muxes are explicitly setup to individual 32 bit
counters driven off system crystal (HFOSC) as default.

Especially useful for boards like the TI J721s2-EVM where the alias is

As the binding for "current-speed" states, this should only be used
when the baud rate of an attached device cannot be detected. This is
the case for our attached on-board USB-to-UART converter used for
early kernel console. For all other unconnected/disabled ports this
can be configured in userspace later, DT is not the place for device
configuration, especially when there are already standard ways to
set serial baud in userspace.
Remove setting baud for all disabled serial ports and move setting
it for the couple enabled ports down into the board files.

MAIN_PLL0 has a flag set in DM (Device Manager) that removes it's
capability to re-initialise clock frequencies. CPTS and RGMII has
MAIN_PLL3 as their parent which does not have this flag. While RGMII
needs this reinitialisation to default frequency to be able to get
250MHz with its divider, CPTS can not get its required 200MHz with its
divider. Thus, move CPTS clock parent on J721S2 from MAIN_PLL3_HSDIV1 to
MAIN_PLL0_HSDIV6.
(Note: even GTC will be moved from MAIN_PLL3 to MAIN_PLL0 in U-Boot side
for the same reason)

Security Management Subsystem(SMS) has it's own unique secure
proxy as part of Security Accelerator (SA3) module. This is used
for communicating with ROM and for special usecases such as HSM
operations. In addition MCU island has it's own secure proxy for
usecases involving the MCU micro controllers. These are in addition
to the one in the main domain DMSS subsystem that is used for general
purpose communication.
Describe the nodes for use with bootloaders and firmware that require
these communication paths which uses interrupts to corresponding micro
controller interrupt controller. Mark the node as disabled since these
instances do not have interrupts routed to the main processor by
default for a complete description of the node.
