Subject: [PATCH 00/12] Add RTC support for the Renesas RZ/G3S SoC

Hi,

On the Renesas RZ/G3S SoC the RTC clock is provided by the VBATTB
IP. A 32 KHz crystall oscillator could be connected to the VBATTB
input pins. The logic to control this clock (and pass it to RTC)
is inside the VBATTB IP. For this, the clk-vbattb driver was added
(patches 01-04/12).

Patches 05-06/12 add the RTC driver.

Patches 07-10/12 update the device trees with proper nodes to enable RTC.

Patches 11-12/12 enable proper config flags for RTC to work on RZ/G3S SoC.

Thank you,
Claudiu Beznea
