Hi All,

This patch series adds SYSCON support to configure and retrieve boot
status information from the CPG block for the RZ/V2H(P) and RZ/G3E SoCs.
Summary of Changes,

    Clock:
        Add syscon compatible support to the CPG block in bindings and
        device trees.

    Watchdog:
        Document the renesas,r9a09g057-syscon-wdt-errorrst property.
        Update the watchdog driver to fetch and report boot status via
        Error Reset Registers (CPG_ERROR_RSTm) and configure the
        CPG_ERRORRST_SEL2 register.

    Device Tree:
        -Add the syscon property to CPG nodes in R9A09G057 and R9A09G047
         SoC DTSI.
        -Add the renesas,syscon-cpg-error-rst property to WDT nodes in
         R9A09G057 and R9A09G047 SoC DTSI.

v3->v4
- Added support to configure CPG_ERRORRST_SEL2 register
- Updated commit messages

v2->v3
- Updated comment section to mention there aren't any ABI breakages with
  this patch series.

Cheers,
Prabhakar

Wasn't the plan to use a DT property under /chosen instead?
(Yes, I go to great lengths to avoid reviewing and accepting patches
 adding syscon compatible values anywhere ;-)

Oh, I  guess that's the reason why you changed your mind.
I will reply to that patch...
