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 V6:
- added SoC-specific compatible value to syscon node and documented it
- given more patch description for below patch
ARM: dts: update watchdog device nodes for Exynos5250 and Exynos5420
- added platform_device_id array for watchdog devices
- selected MFD_SYSCON in Kconfig entry for watchdog
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>
