    Subject[PATCH v4 00/12] watchdog: s3c2410: Add Exynos850 support
    Date
    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
