[PATCH] ARM: multi_v7_defconfig: Add SCMI reset support

[PATCH] ARM: multi_v7_defconfig: Add SCMI reset support

[Etienne Carriere]

SCMI reset controllers are used in the ARMv7 STMicroelectronics stm32mp
boards:
- for STM32MP13: stm32mp135f-dk
- for STM32MP15 boards with SCMI variant, introduced by commit 5b7e58313a77
  ("ARM: dts: stm32: Add SCMI version of STM32 boards (DK1/DK2/ED1/EV1)")
  * stm32mp157c-ev1-scmi
  * stm32mp157c-ed1-scmi
  * stm32mp157c-dk2-scmi
  * stm32mp157a-dk1-scmi

Just one question before to apply this patch. CONFIG_RESET_SCMI is set 
by the following dependency in drivers/reset/Kconfig:

RESET_CONTROLLER [=y] && (ARM_SCMI_PROTOCOL [=y] || COMPILE_TEST [=n])

CONFIG_ARM_SCMI is already set in multi_v7_defconfig.
CONFIG_RESET_CONTROLLER seems to be set in each platform Kconfig.

So not sure we need to force CONFIG_RESET_SCMI in the multi_v7_defconfig.

Regards
Alex

My bad. Thanks for noticing that to me. Indeed the default directive in
drivers/reset/Kconfig together with arm/multi_v7_defconfig makes CONFIG_RESET_SCMI
be enabled.

Sorry for the noise, you can discard my patch request.

Best regards,
Etienne
