Subject: [PATCH V5 0/3] Add watchdog DT nodes and use syscon regmap interfac to configure pmu registers
Date: Thu, 31 Oct 2013 11:30:47 +0530 [thread overview]
Message-ID: <1383199250-15405-1-git-send-email-l.krishna@samsung.com> (raw)
This patchset does the following things
- Adds pmusysreg device node to exynos5.dtsi file
- Adds watchdog DT nodes to Exynos5250 and 5420
- Uses syscon regmap interface to configure pmu registers
to mask/unmask enable/disable of watchdog.
This patch set is rebased on Kgene's for-next branch and tested on SMDK5420
Changes since V4:
- changed the node name from pmusysreg to syscon and node label from pmu_sys_reg to pmu_syscon
- changed the property name from samsung,pmusysreg to samsung,syscon-phandle
- used regmap_update_bits instead of remap_read/regmap_write
- Addressed other comments given by Tomasz Figa <t.figa@samsung.com>
Changes since V3:
- changed the compatible strings for watchdog node
- splitted up adding pmusysreg node and made it separate patch
- Addressed comments given by Sachin Kamat <sachin.kamat@linaro.org>
Changes since V2:
- used syscon regmap interface to configure pmu registers in WDT driver
(suggested by Tomasz Figa <t.figa@samsung.com>)
Changes since V1:
- Added new compatible string for Exynos5 SoCs
- Introduced quirk mechanism to program PMU registers
- Addressed comments given by Tomasz Figa <t.figa@samsung.com>
