ASoC: rsnd: Add RZ/G3E audio driver support
John Madieu <john.madieu.xa@bp.renesas.com> says: 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 audmapp clock/reset for Audio DMAC peri-peri - Per-SSI and per-module reset controllers via CPG - Unprefixed DT sub-node names (ssi, ssiu, src, ...) instead of rcar_sound,xxx - Hyphenated indexed clock/reset names (ssi-0, src-0, adg-ssi-0, audio-clka, ...) instead of the legacy dotted form Link: https://patch.msgid.link/20260525110230.4014435-1-john.madieu.xa@bp.renesas.com

+description:
+ The RZ/G3E (R9A09G047) sound controller is based on R-Car Sound IP
+ with extended DMA channel support (up to 5 DMACs per direction),
+ additional clock domains (47 clocks including per-SSI ADG clocks),
+ and additional reset lines (14 including SCU, ADG and Audio DMAC
+ peri-peri resets). SSI operates exclusively in BUSIF mode with
+ 2-4 BUSIF channels per SSI.
