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 V11:
- Added EXYNOS5 prefix to REG_OFFSET defines (suggested by Tomasz)
- NEEDS_PMU_CONFIG => HAS_PMU_CONFIG (suggested by Olof, Guenter)
- Move QUIRK_HAS_PMU_CONFIG check to s3c2410wdt_mask_and_disable_reset
(suggested by Guenter)
changes since V10:
- followed coding style rules
- removed duplicate error message suggested by Guenter Roeck
<[email protected]>
changes since V9:
- added descriptions to s3c2410_wdt_variant structure fields
- moved calling s3c2410wdt_mask_and_disable_reset() function above
s3c2410wdt_start() call in probe
- put dev_err message back to s3c2410wdt_mask_and_disable_reset()
function
(suggested by Doug Anderson <[email protected]>)
changes since V8:
- modified the patch description for the below patch
"watchdog: s3c2410_wdt: use syscon regmap interface to configure pmu
register"
- removed MODULE_ALIAS in watchdog driver
- changed dev_warn to dev_err in one failure case handling (suggested
by Guenter Roeck <[email protected]>)
- renamed variable name from pmu_config to drv_data
- changed the compatible field description in documentation file
(suggested by Tomasz Figa <[email protected]>)
changes since V7:
- re-ordered the patches in the series
- moved pmu_config_s3c2410 structure out of ifdef CONFIG_OF
and limited only this structure to platform match table
- renamed structure name from s3c_wdt_driver_ids to s3c2410_wdt_ids
- removed exynos variants from platform match table
(suggested by Tomasz Figa <[email protected]>)
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 <[email protected]>
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 <[email protected]>
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 <[email protected]>
Changes since V2:
- used syscon regmap interface to configure pmu registers in WDT driver
(suggested by Tomasz Figa <[email protected]>)
Changes since V1:
- Added new compatible string for Exynos5 SoCs
- Introduced quirk mechanism to program PMU registers
- Addressed comments given by Tomasz Figa <[email protected]>
