[PATCH 2/2] arm64: dts: ti: Add basic support for phyBOARD-Izar-AM68x

[Dominik Haller]

The phyCORE-AM68x/TDA4x [1] is a SoM (System on Module) featuring TI's
AM68x/TDA4x SoC. It can be used in combination with different carrier
boards. This module can come with different sizes and models for DDR,
eMMC, SPI NOR Flash and various SoCs from the AM68x/TDA4x (J721S2) family.

A reference carrier board design, called phyBOARD-Izar is used for the
phyCORE-AM68x/TDA4x development kit [2].

    Supported features:
      * Debug UART
      * 2x SPI NOR Flash
      * eMMC
      * 2x Ethernet
      * Micro SD card
      * I2C EEPROM
      * I2C RTC
      * 2x I2C GPIO Expander
      * LEDs
      * USB 5 Gbit/s
      * PCIe

For more details see the product pages for the SoM and the
development kit:

Can we drop the whitespace prefix?

Could you share the bootlog in the diffstat along with output of
deferred_devices Using the default defconfig -> I want to make sure
there are no defconfig updates needed.

Could you order this slightly differently:

mmc
ethernet

I'll add a bootlog using the default defconfig to the v2 with the style
fixes.
deferred_devices is empty.
PCIe and the TMP102 temperature sensors are not enabled with the
defconfig as of v6.15-rc1. I plan to send a separate patch with
CONFIG_SENSORS_TMP102=m but if you can queue that in with the
devicetree I can simply add that to this series.

you can  post it as a single series and I can pick to the correct
branches.
