Hi,

Series backports the RTC support for the Renesas RZ/G3S SoC.
Along with a clock driver for the clock provided the VBATTB
is included as this is critical for the RTC to work, as it feeds
the RTC counter.

For the VBATTB clock driver the following patches were also
backported:
- clk: gate: Add devm_clk_hw_register_gate()
- clk: mux: Introduce devm_clk_hw_register_mux_parent_hws()
- clk: Add Sunplus SP7021 clock driver
- clk: fixed-factor: add fwname-based constructor functions

and adjusted accordingly, if needed.

Thank you,
Claudiu Beznea

1/ "clk: Add Sunplus SP7021 clock driver" will need either update or
changed description. For the rest you can add

I'll have some minor comments for 10/, but that's best tweaked in
mainline.

Best regards,
