[PATCh v3 00/14] ASoC: rsnd: Add RZ/G3E audio driver support

[John Madieu]

Add audio support for the Renesas RZ/G3E SoC to the R-Car Sound
driver. The RZ/G3E audio subsystem is based on R-Car Sound IP but
has several differences requiring dedicated handling:

  - SSI operates exclusively in BUSIF mode (no PIO)
  - 2-4 BUSIF channels per SSI (layout differs from R-Car)
  - Separate register regions for SCU, ADG, SSIU, SSI accessed by name
  - Per-SSI ADG and SSIF supply clocks
  - Dedicated audmacpp clock/reset for Audio DMAC peri-peri
  - Per-SSI and per-module reset controllers via CPG

This new series is an independent subset of v2 [1] with only ASoC-specific
patches.

Changes:

v3:
 - Split out from v2 series [1] to ASoC-specific patchset.

v2:
 - Split of rsnd.yaml into common and R-Car-specific schemas
 - Introduce RZ/G3E sound binding as a standalone schema
 - Addressed Kuninori'comments, details are in individual patches
