While at it, do a bit of cleaning up. Changes in v2: - Added patch to fail probe if no valid timeout was found, as suggested by Guenter Roeck (03/12) - Extracted code for separating disable/mask functions into separate patch (06/12) - Added patch for inverting mask register value (07/12) - Extracted PMU cleanup code to separate patch, to ease the review and porting (09/12) - Added patch for removing not needed 'err' label in probe function (11/12) - Addressed all outstanding review comments on mailing list Sam Protsenko (12): dt-bindings: watchdog: Require samsung,syscon-phandle for Exynos7 dt-bindings: watchdog: Document Exynos850 watchdog bindings watchdog: s3c2410: Fail probe if can't find valid timeout watchdog: s3c2410: Let kernel kick watchdog watchdog: s3c2410: Make reset disable register optional watchdog: s3c2410: Extract disable and mask code into separate functions watchdog: s3c2410: Implement a way to invert mask reg value watchdog: s3c2410: Add support for WDT counter enable register watchdog: s3c2410: Cleanup PMU related code watchdog: s3c2410: Support separate source clock watchdog: s3c2410: Remove superfluous err label watchdog: s3c2410: Add Exynos850 support .../bindings/watchdog/samsung-wdt.yaml | 47 ++- drivers/watchdog/s3c2410_wdt.c | 289 +++++++++++++----- 2 files changed, 254 insertions(+), 82 deletions(-) -- 2.30.2
