fce5d07316 arm64: tegra: Sort Tegra132 XUSB clocks correctly
Make the order of the clocks and clock-names properties match the order
in the device tree bindings. This isn't strictly necessary from a point
of view of the operating system because matching will be done based on
the clock-names, but it makes it easier to validate the device trees

7fa307524a arm64: tegra: Fixup SYSRAM references
The json-schema bindings for SRAM expect the nodes to be called "sram"
rather than "sysram" or "shmem". Furthermore, place the brackets around
the SYSRAM references such that a two-element array is created rather
than a two-element array nested in a single-element array. This is not
relevant for device tree itself, but allows the nodes to be properly
validated against json-schema bindings.

4f45fb0bd3 arm64: tegra: Extend APE audio support on Jetson platforms
Extend APE audio support by adding more audio components such as SFC,
MVC, AMX, ADX and Mixer. These components can be plugged into an audio
path and required processing can be done. ASoC audio-graph based sound
driver is used to facilitate this and thus extend sound bindings as
well.

The components in the path may require different PCM parameters (such
as sample rate, channels or sample size). Depending on the pre-defined
audio paths, these can be statically configured with "convert-xxx" DT
properties in endpoint subnode. The support for the rate and channel
conversion is already available in generic audio-graph driver. Sample
size conversion support can be added based on the need in future.

The support is extended for following platforms:
 * Jertson TX1
 * Jetson Nano
 * Jetson TX2
 * Jetson AGX Xavier
 * Jetson Xavier NX

As of commit c7289b1c8a ("arm64: tegra: Enable SMMU support on

there was a bit of overlap between the SMMU enablement and the PCIe

these devices, since by default the ARM SMMU will fault.

b8928c2b5d arm64: tegra: Consolidate audio card names
The current scheme for audio card names is suboptimal because it causes
the automatically generated names (for ID and driver) to be truncated,
which in turn can cause conflicts.

Introduce a new scheme which reuses the board model for the names and
appends the "HDA" and "APE" suffixes for the HDA and APE, respectively.
As a side-effect these suffixes end up being used as the ID of the SoC
sound cards which makes it easy for users to select them when using the
ALSA command-line utilities, for example.

As a separate measure, the driver name for the cards is now set by the
corresponding audio driver (either tegra-hda or tegra-ape), making it a
more useful identifier than the currently normalized card name.

75c82a25b5 arm64: tegra: Set fw_devlink=on for Jetson TX2
Commit 5d25c476f2 ("Revert "arm64: tegra: Disable the ACONNECT for
Jetson TX2"") re-enabled the Tegra ADMA and ACONNECT drivers to support
audio on Jetson TX2. However, this revert was dependent upon commit
e590474768 ("driver core: Set fw_devlink=on by default") and without
this commit, enabling the ACONNECT is causing resume from system suspend
to fail on Jetson TX2. Resume fails because the ACONNECT driver is being
resumed before the BPMP driver, and the ACONNECT driver is attempting to
power on a power-domain that is provided by the BPMP.

Commit e590474768 ("driver core: Set fw_devlink=on by default") has
since been temporarily reverted while some issues are being
investigated. This is causing resume from system suspend on Jetson TX2
to fail again. Rather than disable the ACONNECT driver again, fix this
by setting fw_devlink is set to 'on' for Jetson TX2 in the bootargs
specified in device-tree.

HDA initialization is failing occasionally on Tegra210 and following
print is observed in the boot log. Because of this probe() fails and
no sound card is registered.

  [16.800802] tegra-hda 70030000.hda: no codecs found!

Codecs request a state change and enumeration by the controller. In
failure cases this does not seem to happen as STATETS register reads 0.

The problem seems to be related to the HDA codec dependency on SOR
power domain. If it is gated during HDA probe then the failure is
observed. Building Tegra HDA driver into kernel image avoids this
failure but does not completely address the dependency part. Fix this
problem by adding 'power-domains' DT property for Tegra210 HDA. Note
that Tegra186 and Tegra194 HDA do this already.

The Jetson Xavier NX board routes UARTA to the 40-pin header and UARTC

Combined UART (TCU) driver or the Tegra 8250 driver. By default, the
TCU will use UARTC on Jetson Xavier NX. Currently, device-tree for
Xavier NX enables the TCU and the Tegra 8250 node for UARTC. Fix this
by disabling the Tegra 8250 node for UARTC and enabling the Tegra 8250
node for UARTA.

Commit ff4c371d2b ("arm64: defconfig: Build ADMA and ACONNECT driver")
enable the Tegra ADMA and ACONNECT drivers and this is causing resume
from system suspend to fail on Jetson TX2. Resume is failing because the
ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT
driver is attempting to power on a power-domain that is provided by the
BPMP. While a proper fix for the resume sequencing problem is identified,
disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system
suspend.

Please note that ACONNECT driver is used by the Audio Processing Engine
(APE) on Tegra, but because there is no mainline support for APE on
Jetson TX2 currently, disabling the ACONNECT does not disable any useful
feature at the moment.

d5237c7c9b arm64: tegra: Describe interconnect paths on Tegra194
On Tegra194, all clients of the memory subsystem can generally address
40 bits of system memory. However, bit 39 has special meaning and will
cause the memory controller to reorder sectors for block-linear buffer
formats. This is primarily useful for graphics-related devices.

Use of bit 39 must be controlled on a case-by-case basis. Buffers that
are used with bit 39 set by one device may be used with bit 39 cleared
by other devices.

Care must be taken to allocate buffers at addresses that do not require
bit 39 to be set. This is normally not an issue for system memory since
there are no Tegra-based systems with enough RAM to exhaust the 39-bit
physical address space. However, when a device is behind an IOMMU, such
as the ARM SMMU on Tegra194, the IOMMUs input address space can cause
IOVA allocations to happen in this region. This is for example the case
when an operating system implements a top-down allocation policy for IO
virtual addresses.

To account for this, describe the path that memory accesses take through
the system. Memory clients will send requests to the memory controller,
which forwards bits [38:0] of the address either to the external memory
controller or the SMMU, depending on the stream ID of the access. A good
way to describe this is using the interconnects bindings, see:

    Documentation/devicetree/bindings/interconnect/interconnect.txt

The standard "dma-mem" path is used to describe the path towards system
memory via the memory controller. A dma-ranges property in the memory
controller's device tree node limits the range of DMA addresses that the
memory clients can use to bits [38:0], ensuring that bit 39 is not used.

bba25915b1 arm64: tegra: Fix ethernet phy-mode for Jetson Xavier
The 'phy-mode' property is currently defined as 'rgmii' for Jetson
Xavier. This indicates that the RGMII RX and TX delays are set by the
MAC and the internal delays set by the PHY are not used.

If the Marvell PHY driver is enabled, such that it is used and not the
generic PHY, ethernet failures are seen (DHCP is failing to obtain an
IP address) and this is caused because the Marvell PHY driver is
disabling the internal RX and TX delays. For Jetson Xavier the internal
PHY RX and TX delay should be used and so fix this by setting the
'phy-mode' to 'rgmii-id' and not 'rgmii'.

f9f711efd4 arm64: tegra: Fix Tegra194 PCIe compatible string
If the kernel configuration option CONFIG_PCIE_DW_PLAT_HOST is enabled
then this can cause the kernel to incorrectly probe the generic
designware PCIe platform driver instead of the Tegra194 designware PCIe
driver. This causes a boot failure on Tegra194 because the necessary
configuration to access the hardware is not performed.

The order in which the compatible strings are populated in Device-Tree
is not relevant in this case, because the kernel will attempt to probe
the device as soon as a driver is loaded and if the generic designware
PCIe driver is loaded first, then this driver will be probed first.
Therefore, to fix this problem, remove the "snps,dw-pcie" string from
the compatible string as we never want this driver to be probe on
Tegra194.

MC and a ranges property is used to describe the register ranges.

A dma-ranges property is also added to describe that all memory clients
can address up to 39 bits using the memory controller client interface
(MCCIF), unless otherwise limited by the DMA engines of the hardware. A
memory client can technically use 40 bits of addresses, but the memory
controller on Tegra194 uses bit 39 to determine the XBAR format used to
access memory. Use of this bit needs to be explicitly controlled by the
operating system drivers for devices that can use this on-the-fly format
conversion. Using the dma-ranges property prevents the operating system
from using the bit implicitly, for example in I/O virtual address
mappings.

that the connected device doesn't have CLKREQ support. Hence, it makes
sense to assume that there is no CLKREQ support by default and it can

Commit 4fdbfd60a3a2 ("arm64: tegra: Add PCIe slot supply information
in p2972-0000 platform") added regulators for the PCIe slot on the
Jetson Xavier platform. One of these regulators has an active-low enable
and this commit incorrectly added an active-low specifier for the GPIO
which causes the following warning to occur on boot ...

 WARNING KERN regulator@3 GPIO handle specifies active low - ignored

The fixed-regulator binding does not use the active-low flag from the
gpio specifier and purely relies of the presence of the
'enable-active-high' property to determine if it is active high or low
(if this property is omitted). Fix this warning by setting the GPIO
to active-high in the GPIO specifier. Finally, remove the
'enable-active-low' as this is not a valid property.

There are a few issues with the GPU regulator defined for Jetson Nano
which are:

1. The GPU regulator is a PWM based regulator and not a fixed voltage
   regulator.
2. The output voltages for the GPU regulator are not correct.
3. The regulator enable ramp delay is too short for the regulator and
   needs to be increased. 2ms should be sufficient.
4. This is the same regulator used on Jetson TX1 and so make the ramp
   delay and settling time the same as Jetson TX1.

7278358407 arm64: tegra: Disable XUSB support on Jetson TX2
The recently introduced XUSB support for Jetson TX2 is causing boot, CPU
hotplug and suspend/resume failures according to several reports.

Temporarily work around this by disabling the XUSB controller and XUSB
pad controller nodes in device tree, while we figure out what's causing
this.

f2a465e718 arm64: tegra: Enable SMMU translation for PCI on Tegra186
Commit 954a03be03 ("iommu/arm-smmu: Break insecure users by disabling
bypass by default") intentionally breaks all devices using the SMMU in
bypass mode. This breaks, among other things, PCI support on Tegra186.
Fix this by populating the iommus property and friends for the PCIe
controller.

c8e3993dd5 dt-bindings: hwmon (pwm-fan) Remove dead "cooling-*-state" properties
The old "cooling-{min,max}-state" properties for thermal bindings were
ratified to "cooling-{min,max}-level" by commit eb168b70de ("of:
thermal: Fix inconsitency between cooling-*-state and cooling-*-level"),
which were later removed entirely by commit e04907dbc2 ("dt-bindings:
thermal: Remove "cooling-{min|max}-level" properties").

The pwm-fan binding, however, was apparently in-flight in parallel with
that ratification, and so managed to introduce an example of the old
properties which escaped the scope of the later cleanup and has thus
continued to be dutifully copied for new boards despite being useless.
Clean up these remaining undocumented anachronisms to minimise any
further confusion.

6772cd0eac arm64: tegra: Add NVIDIA Jetson Nano Developer Kit support
The Jetson Nano Developer Kit is a Tegra X1 based development board. It
is similar to Jetson TX1 but it is not pin compatible. It features 4 GB
of LPDDR4, an SPI NOR flash for early boot firmware and an SD card slot
used for storage.

HDMI 2.0 or DP 1.2 are available for display, four USB ports (3 USB 2.0
and 1 USB 3.0) can be used to attach a variety of peripherals and a PCI
Ethernet controller provides onboard network connectivity. An M.2 Key-E
slot with PCIe x1 adds additional possibilities.

A 40-pin header on the board can be used to extend the capabilities and
exposed interfaces of the Jetson Nano.

a38570c22e arm64: tegra: Add nodes for TCU on Tegra194
Add nodes required for communication through the Tegra Combined UART.
This includes the AON HSP instance, addition of shared interrupts
for the TOP0 HSP instance, and finally the TCU node itself. Also
mark the HSP instances as compatible to tegra194-hsp, as the hardware
is not identical but is compatible to tegra186-hsp.

31af04cd60 arm64: dts: Remove inconsistent use of 'arm,armv8' compatible string
The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some
platforms. Remove it from those platforms.

This fixes warnings generated by the DT schema.
