The impact is mainly on the MCU hold boot management. Three configurations have to be supported: 1) Configuration without OP-TEE SCMI (legacy): Trusted context not activated - The MCU reset is controlled through the Linux RCC reset driver. - The MCU HOLD BOOT is controlled through The RCC sysconf. 2) Configuration with SCMI server: Trusted context activated - The MCU reset is controlled through the SCMI reset service. - The MCU HOLD BOOT is no more controlled through a SMC call service but through the SCMI reset service. 3) Configuration with OP-TEE SMC call (deprecated): Trusted context activated - The MCU reset is controlled through the Linux RCC reset driver. - The MCU HOLD BOOT is controlled through The SMC call. In consequence this series: - adds the use of the SCMI reset service to manage the MCU hold boot, - determines the configuration to use depending on the presence of the "reset-names" property if ( "reset-names" property contains "hold_boot") then use reset_control services else use regmap access based on "st,syscfg-holdboot" property. - set the DT st,syscfg-tz property as deprecated Arnaud Pouliquen (4): dt-bindings: remoteproc: st,stm32-rproc: Rework reset declarations remoteproc: stm32: Allow hold boot management by the SCMI reset controller ARM: dts: stm32: Update reset declarations ARM: dts: stm32: fix m4_rproc references to use SCMI .../bindings/remoteproc/st,stm32-rproc.yaml | 44 +++++++++-- arch/arm/boot/dts/stm32mp151.dtsi | 2 +- arch/arm/boot/dts/stm32mp157a-dk1-scmi.dts | 6 +- arch/arm/boot/dts/stm32mp157c-dk2-scmi.dts | 6 +- arch/arm/boot/dts/stm32mp157c-ed1-scmi.dts | 6 +- arch/arm/boot/dts/stm32mp157c-ev1-scmi.dts | 6 +- drivers/remoteproc/stm32_rproc.c | 76 ++++++++++++++----- 7 files changed, 111 insertions(+), 35 deletions(-) -- 2.25.1
