From: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
Add the DT node for the RTC IP available on the Renesas RZ/G3S SoC.
Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@xxxxxxxxxxxxxx>
---
Changes in v4:
- dropped the assigned-clocks, assigned-clock-parents properties as they
fit better on vbattb node
- moved the RTC close to serial node for ordering
Changes in v3:
- added CPG clock, power domain, reset
- and assigned-clocks, assigned-clock-parents to configure the
VBATTCLK
- included dt-bindings/clock/r9a08g045-vbattb.h
Changes in v2:
- updated compatibles
