Hi,

Series enables the audio support for the Renesas RZ/G3S
SoC along with runtime PM and suspend to RAM.

Patches:
-    01/25 - add clock, reset and power domain support
- 02-04/25 - update versaclock3 clock generator driver to support the
             5L35023 hardware variant; versaclock3 provides clocks for
             the audio devices (SSIF, DA7212 codec)
-    05/25 - add pin control support for audio
- 06-20/25 - add SSIF support for the RZ/G3S SoC; fixes and cleanups
             were also included
- 21-25/25 - add device tree support

Merge strategy, if any:
- clock patches (01-04/25) can go through the Renesas tree
- pinctrl patch (05/25) can go though the Renesas tree
- audio patches (06-20/25) can go through the audio tree
- device tree patches (21-25/25) can go through the Renesas tree

Thank you,
Claudiu Beznea

Changes in v2:
- fixed typos pointed out in the review process
- dropped da7213 patches already applied
- dropped patch "ASoC: sh: rz-ssi: Use a proper bitmask for clear bits"
  as requested in the review process
