Browse Source 
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.
