2013-06-15ARM: EXYNOS: Remove legacy power domain registration codeTomasz Figa1-93/+1
This patch removes static definitions of power domains and code responsible for registering them and adding devices to them, since only DT based boot is now supported on Exynos.

2013-06-10ARM: EXYNOS: no more support non-DT for EXYNOS SoCsKukjin Kim1-7/+0
As we discussed in mailing list, non-DT for EXYNOS SoCs will not be supported from v3.11. This patch removes regarding files for non-DT including board files and defconfig.

2012-11-21ARM: EXYNOS: Bind devices to power domains using DTTomasz Figa1-0/+82
This patch adds a way to specify bindings between devices and power domains using device tree. A device can be bound to particular power domain by adding a power-domain property containing a phandle to the domain. The device will be bound to the domain before binding a driver to it and unbound after unbinding a driver from it.

2012-11-21ARM: EXYNOS: Detect power domain state on registration from DTTomasz Figa1-3/+5
Initial state of power domains might vary on different boards and with different bootloaders. This patch adds detection of initial state of power domains when being registered from DT.

2012-08-10ARM: exynos: exynos_pm_add_dev_to_genpd may be unusedArnd Bergmann1-1/+1
exynos_pm_add_dev_to_genpd is used if one or more out of a large number of Kconfig symbols are enabled. However the new exynos_defconfig selects none of those, so the function becomes unused. Marking it so lets the compiler automatically discard it. Without this patch, building exynos_defconfig results in: arch/arm/mach-exynos/pm_domains.c:118:123: warning: 'exynos_pm_add_dev_to_genpd' defined but not used [-Wunused-function] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Thomas Abraham <thomas.abraham@linaro.org> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Cc: Rafael J.

2012-07-12ARM: EXYNOS: register devices in 'need_restore' state for pm_domainsMarek Szyprowski1-1/+3
Commit ca1d72f033 ('PM / Domains: Make it possible to add devices to inactive domains') introduced possibility to add devices to inactive power domains and added pm_genpd_dev_need_restore() function which lets platform core to notify power domain core that the specified device must be restored (with its runtime_resume() callback) before first use. This patch adds the pm_genpd_dev_need_restore() call what brings back the suspend/resume behaviour for the client devices known from the previous power domain driver (removed by commit 91cfbd4ee0 - 'ARM: EXYNOS: Hook up power domains to generic power domain infrastructure'). Client device drivers relay on that suspend/resume behaviour, thus this patch fixes runtime pm operation for client devices.

2012-07-12ARM: EXYNOS: read initial state of power domain from hw registersMarek Szyprowski1-3/+6
Some bootloaders disable unused power domains to reduce power consuption. Power domain driver can easily read the actual state from the hardware registers instead of assuming that their initial state is always 'on'.

2012-01-27ARM: EXYNOS: Hook up power domains to generic power domain infrastructureThomas Abraham1-0/+195
Add support for generic power domain for Exynos4 platforms and remove the Samsung specific power domain control for Exynos4. The generic power domain infrastructure is used to control the power domains available on Exynos4. For non-dt platforms, the power domains are statically instantiated. For dt platforms, the power domain nodes found in the device tree are instantiated.
