I know that I have to fix sdio pins nodes in this file to keep the same spirit for all group names. If there is no V3 I wil do it directly when I'll apply DT patches if you agree.

I know that I have to > fix sdio pins nodes in this file to keep the same spirit for all group > names. I have looked at the file arch/arm/boot/dts/stm32f7-pinctrl.dtsi, and based on the following nodes: usart1_pins_a: usart1-0 i2c1_pins_b: i2c1-0 can1_pins_a: can1-0 I have decided to rename ltdc-pins-a-0 to ltdc-0. I hope you agree.
