01aabf97d1 ARM: dts: stm32: Migrate U-boot nodes to U-boot DT files for stm32f7
In order to prepare and ease future DT synchronization with kernel
DT, migrate all U-boot specific nodes/properties/addons to
U-boot DT files.

Migrate also DT nodes which are not yet available on kernel DT side
as ethernet, ltdc and qspi nodes.

Fix ethernet_mii pins and add missing qspi_pins for stm32746g-eval

77729bd744 ARM: DTS: stm32: add MMC nodes for stm32f746-disco and stm32f769-disco
Add DT nodes to enable ARM_PL180_MMCI IP support for STM32F746
and STM32F769 discovery boards

There is a hardware issue on these boards, it misses a pullup on the GPIO line
used as card detect to allow correct SD card detection.
As workaround, cd-gpios property is not present in DT.
So SD card is always considered present in the slot.

1113ad49dc serial: stm32x7: align compatible with kernel one
stm32x7.c driver is dedicated for STM32F7.
In kernel, "st,stm32-usart" and "st,stm32-uart" compatible
strings are dedicated for STM32F4.

To keep U-boot and kernel aligned, replace the serial compatible
string from "st,stm32-usart", "st,stm32-uart" to
"st,stm32f7-usart", "st,stm32f7-uart" specific for STM32F7.
