Subject: [PATCH v2 0/4] arm64: Hi6220: enable CPU idle states
Date: Tue, 13 Oct 2015 08:58:12 +0800 [thread overview]
Message-ID: <1444697896-4323-1-git-send-email-leo.yan@linaro.org> (raw)
This patch series is to enable CPU idle states for Hi6220.
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
