59000ebe0b ARM: dts: stm32: Fix AV96 eMMC pinmux
Commit 500327e2ea ("ARM: dts: stm32mp1: DT alignment with Linux kernel v5.8-rc1")
renamed sdmmc2_d47_pins_b phandle to sdmmc2_d47_pins_c, but without updating
the AV96 DT which uses that phandle. Linux missed similar update as well and
it was only added in commit 1ad6e36ec266 ("ARM: dts: stm32: Fix sdmmc2 pins
on AV96") .

Update the AV96 DT pinmux phandle, otherwise eMMC 8bit mode does not work
and access to eMMC takes a very long time to fall back to 4bit mode.

6ed83edfc0 ARM: dts: rename stm32mp15xx-avenger96 ethernet0_rgmii_pins
Alignment with pins name used in Linux kernel v5.8.

It is a preleminary step for device tree alignment.

39a18aaa33 ARM: dts: stm32: Repair I2C2 operation on AV96
The I2C2 uses different pinmux on AV96, use correct pinmux and
also add comments about the I2C being present on the "low-speed"
expansion connector X6.

1ca5017418 ARM: dts: stm32: Fix AV96 and DHCOR split
The commit 132e5b6898 ("ARM: dts: stm32: Split AV96 into DHCOR SoM
and AV96 board") was not applied correctly and in full, and omitted
an important split of the SoM into 3V3 and 1V8 options. The Avenger96
board is based on the 1V8 IO option of the DHCOR SoM, however this is
an optional modification of the 3V3 IO DHCOR SoM with extra on-SoM
regulator to cater for the 96boards 1V8 IO requirements.

Reinstate the split between the 1V8 and 3V3 IO variants.

132e5b6898 ARM: dts: stm32: Split AV96 into DHCOR SoM and AV96 board
The AV96 is in fact an assembly of DH Electronics DHCOR SoM on top
of an AV96 reference board. Split the DTs to reflect that and make
sure to DHCOR SoM can be reused on other boards easily.

It is also highly recommended to configure the board for the DHCOM
make stm32mp15_dhcom_basic_defconfig
make DEVICE_TREE=stm32mp15xx-dhcor-avenger96
as that permits reusing the board code for the DH components, like
accessing and reading out the ethernet MAC from EEPROM.
