Subject: [PATCH v3 0/2] ARM: Exynos: Adapt to generic power domain
Date: Thu, 12 Jan 2012 13:20:07 +0530 [thread overview]
Message-ID: <1326354609-27181-1-git-send-email-thomas.abraham@linaro.org> (raw)
Changes since v2:
- Added CSIS1 to cam power domain.
- Changed some of the Exynos4 prefix to Exynos.
* no changes in first patch.
Changes since v1:
- Added a OF wrapper around __pm_genpd_add_device as suggested by Rafael.
- Added cpu_relax and usleep_range during waits for power domain to be
enabled/disabled.
- Added static registrations of devices to power domains for non-dt
platforms.
The power domains available on Exynos4 are made controllable using the generic
power domain infrastructure. The Samsung specific power domain control code
for Exynos4 is removed. Support for both DT and non-DT Exynos platforms is
added.
The first patch adds device tree support for generic power domain. A device
node is added to the generic power domain strucure that represents a power
domain node in the device tree. Other device nodes in the device tree can
include a property with a phandle of the power domain node which will enable
that device to be associated with a power domain.
The second patch registers available power domains to generic power domain
framework with support for both dt and non-dt platforms. The Samsung specific
power domain control support is removed.
The patchset is based on the following tree
http://git.kernel.org/pub/scm/linux/kernel/git/kgene/linux-samsung.git for-next
with all patches merged from
http://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git linux-next
