In A1/C1, power controller registers such as PWRCTRL_FOCRSTN, PWRCTRL_PWR_OFF, PWRCTRL_MEM_PD and PWRCTRL_ISO_EN, are in the secure domain, and should be accessed from ATF by smc. Changes since v4 at [3]: - add SM_A1_ prefix for PWRC_SET/GET - rename variable and update comments Changes since v3 at [2]: - remove phandle to secure-monitor node Changes since v2 at [1]: - update domain id - include dt-bindings in dts Changes since v1 at [0]: - use APIs from sm driver - rename pwrc_secure_get_power as Kevin suggested - add comments for always on domains - replace arch_initcall_sync with builtin_platform_driver - fix coding style [0] https://lore.kernel.org/linux-amlogic/1568895064-4116-1-git-send-email-jianxin.pan@amlogic.com [1] https://lore.kernel.org/linux-amlogic/1570695678-42623-1-git-send-email-jianxin.pan@amlogic.com [2] https://lore.kernel.org/linux-amlogic/1571391167-79679-1-git-send-email-jianxin.pan@amlogic.com [3] https://lore.kernel.org/linux-amlogic/1572868028-73076-1-git-send-email-jianxin.pan@amlogic.com Jianxin Pan (4): dt-bindings: power: add Amlogic secure power domains bindings firmware: meson_sm: Add secure power domain support soc: amlogic: Add support for Secure power domains controller arm64: dts: meson: a1: add secure power domain controller .../bindings/power/amlogic,meson-sec-pwrc.yaml | 37 ++++ arch/arm64/boot/dts/amlogic/meson-a1.dtsi | 7 + drivers/firmware/meson/meson_sm.c | 2 + drivers/soc/amlogic/Kconfig | 13 ++ drivers/soc/amlogic/Makefile | 1 + drivers/soc/amlogic/meson-secure-pwrc.c | 204 +++++++++++++++++++++ include/dt-bindings/power/meson-a1-power.h | 32 ++++ include/linux/firmware/meson/meson_sm.h | 2 + 8 files changed, 298 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/amlogic,meson-sec-pwrc.yaml create mode 100644 drivers/soc/amlogic/meson-secure-pwrc.c create mode 100644 include/dt-bindings/power/meson-a1-power.h
