Set eMMC clock parents to the defaults which is MAIN_PLL0_HSDIV5_CLKOUT

correct procedure to switch PLL clock source for eMMC and MMC CLK mux is
not glich-free. As a preventative action, lets switch back to the defaults.

c870321e43 arm64: dts: ti: k3-am62: Add cpsw-mac-efuse node to wkup_conf
The WKUP system controller address region contains an eFuse block with
MAC addresses to be used by the Ethernet controller. The property
“ti,syscon-efuse” contains a phandle to a syscon region and an offset
into this region where the MAC addresses can be found. Currently
"ti,syscon-efuse" points to the entire system controller address space
node with an offset to the eFuse IP address.

Instead add a cpsw-mac-efuse node to describe the exact eFuse area. Then
point the Ethernet controller directly to this region, no offset needed.

The DSS supports one each of video pipeline (vid) and video-lite

DPI signals on another (VP2). The video ports are connected to the
pipelines via 2 identical overlay managers (ovr1 and ovr2).

Also add the DT node for DSS clock divider. This is a fixed-factor-clock
and does not have any register. This comes into effect whenenver OLDI
display is used. The input to this divider is a serial clock used by
OLDI TXes. The divider divides the input clock by 7, and provides the
pixel clock to VP1.

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. This is in addition to the one in the main domain DMSS
subsystem that is used for general purpose communication.

Describe the node for use with bootloaders and firmware that require
this communication path which uses interrupts to corresponding micro
controller interrupt controller. Mark the node as disabled since this
instance does not have interrupts routed to the main processor by
default for a complete description of the node.

3308a31c50 arm64: dts: ti: k3-am62: Add general purpose timers for am62
There are 8 general purpose timers on am65 that can be used for things
like PWM using pwm-omap-dmtimer driver. There are also additional four
timers in the MCU domain that do not have interrupts routable for Linux.

We configure the timers with the 25 MHz input clock by default as the
32.768 kHz clock may not be wired on the device. We leave the MCU domain
timers clock mux unconfigured, and mark the MCU domain timers reserved.
The MCU domain timers are likely reserved by the software for the ESM
module.

Compared to am65, the timers on am62 do not have a dedicated IO mux for
the timers. On am62, the timers have different interrupts, clocks and
power domains compared to am65, and the MCU timers are at a different
IO address.
