[PATCH v2 15/18] ARM: dts: imx6q-apalis: Add support for Toradex Ixora V1.2 carrier boards

From: Max Krummenacher
Date: Wed Jun 15 2022 - 07:52:16 EST

From: Max Krummenacher <max.krummenacher@xxxxxxxxxxx>

The Ixora V1.2 carrier board adds SW relevant new features compared to
the V1.1 version.

- An I2C EEPROM is added.
- The SD card slot got a switchable 3.3V supply.
- Pull ups on the SD card signals are not assembled to faciliate 1.8V
speed modes.
- The CAN transceivers got a switchable 3.3V supply.

Add a new device tree and, as the differences are so small rework the
device tree for V1.1 to include the V1.2 device tree and adjust as
needed.
Drop adding the toradex,apalis_imx6q-ixora to the dtb compatible to
adhere to the binding yaml document.

Signed-off-by: Max Krummenacher <max.krummenacher@xxxxxxxxxxx>

Changes in v2:
- removed gpio-keys node. This has been moved to the SoM dtsi in v2
