Subject: [PATCH 01/12] clk: renesas: r9a08g045: Add clock, reset and power domain support for the VBATTB IP
From: Claudiu Beznea <claudiu.beznea.uj@...renesas.com>
The Renesas RZ/G3S SoC has an IP named Battery Backup Function (VBATTB)
that generates the RTC clock. Add clock, reset and power domain support
for it.
