Merge tag 'stm32-dt-for-v6.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/atorgue/stm32 into soc/dt

STM32 DT for v6.9, round 1

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

- MCU:
  - Add DSI support on stm32f769.
  - Add display support on stm32f769-disco.
  - Add stm32f769-disco-mb1166-reva09 board support which belongs to
    the novatek NT35510 panel.

- MPU:
  - STM32MP13:
    - Add CRC support an enable it on stm32mp135f-dk.
    - Enable CRYP on stm32mp135f-dk.

  - STMP32MP15:
   - Fix DSI peripheral clock: use bus clock instead of kernel clock
     for pclk.

   - LXA: driver powerboard lines as open drain.
   - LXA: reduce RGMII drive strenght to reduce EMI emmissions.

  - STM32MP25:
    - Add video encoder / video decoder support.
