[PATCH 0/3] SCMI Update for STM32MP15 boards

[gabriel.fernandez]

From: Gabriel Fernandez <gabriel.fernandez@foss.st.com>

Update for SCMI version of ST boards:
- delete fixed clocks because there are now provided by SCMI
- add missing SCMI impact for DSI IP on DK1/ED1 STM32 board
- fix peripheral clock for CEC 

Gabriel Fernandez (3):
  ARM: dts: stm32: use the correct clock source for CEC on stm32mp151
  ARM: dts: stm32: DSI should use LSE SCMI clock on DK1/ED1 STM32 board
  ARM: dts: stm32: delete fixed clock node on STM32MP15-SCMI
