[PATCH v6 00/10] ARM: stm32: add support for Phycore STM32MP1

[PATCH v6 00/10] ARM: stm32: add support for Phycore STM32MP1

[Steffen Trumtrar]

Hi,

this is the fifth installement of my series for adding support for the
Phytec STM32MP1-based SoM and board.

Phytec itself calls the board "Phycore STM32MP1-3" and has other
endnumbers. I only have access to the "-3" and that's what this series
adds.

    Changes since v5:
      - add reviewed/acked-by
      - cleanup dt_bindings_check warnings
    
    Changes since v4:
      - cleanup usage of "status = okay|disabled"
      - fix remaining non-generic node names
      - rework sai nodes to not duplicate the existing settings in stm32mp151.dtsi
    
    Changes since v3:
      - cleanup board-compatible
      - cleanup aliases
      - rename nodes according to schema
      - use interrupt flag

[PATCH v6 01/10] ARM: dts: stm32: Add alternate pinmux for ethernet

[Steffen Trumtrar]

Add another option for the ethernet0 pins.
It is almost identical to ethernet0_rgmii_pins_c apart from TXD0/1.

This is used on the Phycore STM32MP1.

    However, 'jedec,spi-nor.yaml' defines the pattern
    
        (winbond,)?w25q(16|32(w|dw)?|64(dw)?|80bl|128(fw)?|256))$"
    
    so, this should be good!?
    
    Changes since v5:
      - cleanup dt_bindings_check warnings
    
    Changes since v4:
      - cleanup usage of "status = okay|disabled"
      - fix remaining non-generic node names
      - rework sai nodes to not duplicate the existing settings in stm32mp151.dtsi
    
    Changes since v3:
      - cleanup board-compatible
      - cleanup aliases
      - rename nodes according to schema
      - use interrupt flag
