Subject: [PATCH v2 00/12] watchdog: s3c2410: Add Exynos850 support
Date: Sun, 31 Oct 2021 14:22:04 +0200 [thread overview]
Message-ID: <20211031122216.30212-1-semen.protsenko@linaro.org> (raw)
Exynos850 WDT IP-core differs a bit from existing platforms:
- Another set of PMU registers
- Separate WDT instance for each CPU cluster, having different PMU
registers/bits
- Source clock is different from PCLK
Implement all missing features above and enable Exynos850 WDT support.
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
