Hi All,
This patch series adds SYSCON support to retrieve boot status information for RZ/V2H(P) SoC. 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).
Device Tree: Add the syscon property to CPG and WDT nodes in R9A09G057 and R9A09G047 SoC DTSI.
These changes enable the watchdog driver to identify boot sources like Power-on Reset and Watchdog Reset, improving system diagnostics.
v2->v3 - Updated comment section to mentione there arent any ABI breakages with this patch series.
Cheers, Prabhakar
