Merge tag 'stm32-dt-for-v6.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/dt

STM32 DT for v6.5, round 1

Highlights:
----------

- MCU/MPU:
  - Replace deprecated st,hw-flow-ctrl by uart-has-rtscts.
  - Fix LTDC/DSI warnings.

- MPU:
  - STMP32MP15:
    - Add OTP part number and Vrefint calibration in bsec.
    - M4 hold management updated. As SMC call is deprecated,
      the service is moved on a SCMI service.
    - Add ADC internal channels (VREFINT/VDDCORE).

  - ST:
    - Enable ADC1&2 on STM32MP15 DKx boards.
    - Adopt generic IIO bindings on STM32MP157C ED1
    - Add supplies for OV5640 in STM32MP157C EV1
      to fix yaml validation.
    - Fix i2s bindings to match with the YAML validation (DKx boards).

  - DH:
    - Rearrange MAC EEPROM.
    - Rename AV96 sound card.
    - Adopt generic IIo bindings.
    - Fix audio routing.

  -PHYTEC:
    - Add PHYTEC STM32MP1-3 Dev board based on STM32MP15 PHYTEC SOM.
      This SOM embeds up to 1GB DDR3LP RAM, up to 1GB eMMC,
      up to 16 MB QSPI and up to 128 GB NAND flash.
