Hi6220 uses PSCIv0.2 compliance interface, so directly use ARM's generic CPUIdle driver. Patch 1 is to reserve memory regions so make sure MCU can work well to handle power controlling; Patch 2/3 enable sp804 timer as broadcast timer during idle states; Patch 4 registers CPU power down state and cluster power down state. Changes from v1: * According to Sudeep's review, fix binding for idle-states * According to Rob's review, due timers share same clock source with apb clock, so just only pass one clock phandle Leo Yan (4): arm64: dts: Reserve memory regions for hi6220 arm64: Kconfig: select sp804 timer for ARCH_HISI arm64: dts: add sp804 timer node for Hi6220 arm64: dts: enable idle states for Hi6220 arch/arm64/Kconfig.platforms | 1 + arch/arm64/boot/dts/hisilicon/hi6220-hikey.dts | 16 ++++++++--- arch/arm64/boot/dts/hisilicon/hi6220.dtsi | 40 ++++++++++++++++++++++++++ 3 files changed, 53 insertions(+), 4 deletions(-) -- 1.9.1
