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 V5: - removed status property in DT nodes - changed the return type for the function s3c2410wdt_mask_and_disable_reset() and handled error cases - Handled to get driver data in non-DT cases - Addressed comments given by Tomasz Figa <t.figa@xxxxxxxxxxx> 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@xxxxxxxxxxx> 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@xxxxxxxxxx> Changes since V2: - used syscon regmap interface to configure pmu registers in WDT driver (suggested by Tomasz Figa <t.figa@xxxxxxxxxxx>) 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@xxxxxxxxxxx> Leela Krishna Amudala (3): ARM: dts: Add pmu sysreg node to Exynos5 dtsi file ARM: dts: add watchdog device nodes for Exynos5250 and Exynos5420 watchdog: s3c2410_wdt: use syscon regmap interface to configure pmu register .../devicetree/bindings/watchdog/samsung-wdt.txt | 21 ++- arch/arm/boot/dts/exynos5.dtsi | 12 +- arch/arm/boot/dts/exynos5250.dtsi | 6 +- arch/arm/boot/dts/exynos5420.dtsi | 9 ++ drivers/watchdog/s3c2410_wdt.c | 139 ++++++++++++++++++-- 5 files changed, 170 insertions(+), 17 deletions(-) -- 1.7.10.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
