For each remote proc, reserve memory for IPC and bind the mailbox
assignments. Two memory regions are reserved for each remote processor.
The first region of 1MB of memory is used for Vring shared buffers
and the second region is used as external memory to the remote processor
for the resource table and for tracebuffer allocations.

Add regulator node for AM62P-SK
VCC_3V3_MAIN is the output of LM5141-Q1, and it serves as an input to
TPS22965DSGT which produces VCC_3V3_SYS [1]
VCC_3V3_SYS servers as vin-supply for peripherals like CSI [1].

After the SoC has entered the Deep Sleep mode, USB1 can be used to wakeup
the SoC based on USB events triggered by USB devices. This requires that
the pin corresponding to the Type-A connector remains pulled up even after
the SoC has entered the Deep Sleep mode. Hence, enable Deep Sleep pullup /
pulldown selection for the USB1_DRVBUS pin and set its Deep Sleep state to
PULL_UP.

Device tree best practice is to disable any external interface in the
dtsi and just enable them if needed in the device tree. Thus, disable
the ethernet switch and its ports by default and just enable the ones
used by the EVMs in their device trees.
