ARM: cpuidle: Support asymmetric idle definition Some hardware have clusters with different idle states. The current code does not support this and fails as it expects all the idle states to be identical. Because of this, the Mediatek mtk8173 had to create the same idle state for a big.Little system and now the Hisilicon 960 is facing the same situation. Solve this by simply assuming the multiple driver will be needed for all the platforms using the ARM generic cpuidle driver which makes sense because of the different topologies we can support with a single kernel for ARM32 or ARM64. Every CPU has its own driver, so every single CPU can specify in the DT the idle states. This simple approach allows to support the future dynamIQ system, current SMP and HMP.

It provides a generic idle driver whose idle states are configured
at run-time through DT nodes. The CPUidle suspend backend is
initialized by calling the CPU operations init idle hook

As a result it enables AFTR mode to be used by default on Exynos4210 without the need to hot unplug CPU1 first. The patch is heavily based on earlier cpuidle-exynos4210 driver from Daniel Lezcano: http://www.spinics.net/lists/linux-samsung-soc/msg28134.html Changes from Daniel's code include: - porting code to current kernels - fixing it to work on my setup (by using S5P_INFORM register instead of S5P_VA_SYSRAM one on Revison 1.1 and retrying poking CPU1 out of the BOOT ROM if necessary) - fixing rare lockup caused by waiting for CPU1 to get stuck in the BOOT ROM (CPU hotplug code in arch/arm/mach-exynos/platsmp.c doesn't require this and works fine) - moving Exynos specific code to arch/arm/mach-exynos/pm.c - using cpu_boot_reg_base() helper instead of BOOT_VECTOR macro - using exynos_cpu_*() helpers instead of accessing registers directly - using arch_send_wakeup_ipi_mask() instead of dsb_sev() (this matches CPU hotplug code in arch/arm/mach-exynos/platsmp.c) - integrating separate exynos4210-cpuidle driver into existing exynos-cpuidle one Cc: Colin Cross <ccross@google.com> Cc: Kukjin Kim <kgene.kim@samsung.com> Cc: Krzysztof Kozlowski <k.kozlowski@samsung.com> Cc: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> Signed-off-by: Daniel Lezcano <daniel.lezcano@linaro.org> Acked-by: Kyungmin Park <kyungmin.park@samsung.com> Signed-off-by: Kukjin Kim <kgene@kernel.org>
