Subject: [PATCH v4 00/12] watchdog: s3c2410: Add Exynos850 support
Date: Sun, 21 Nov 2021 18:56:35 +0200 [thread overview]
Message-ID: <20211121165647.26706-1-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 v4:
- Fixed build error when CONFIG_OF is disabled (found by 0-day)
- Added R-b tag by Guenter Roeck to all patches
Changes in v3:
- Renamed "samsung,index" property to more descriptive
"samsung,cluster-index"
- bindings: Disabled "samsung,cluster-index" property for SoCs other
than Exynos850
- Added quirks documentation
- Removed has_src_clk field: clk framework can handle NULL clk; added
s3c2410wdt_get_freq() function instead, to figure out which clock to
use for getting the rate
- Used pre-defined and completely set driver data for cluster0 and
cluster1
- Coding style changes
- Added R-b tags
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
