Subject: [PATCH v4 0/5] Enable I2S support for RK3588/RK3588S SoCs

There are five I2S/PCM/TDM controllers and two I2S/PCM controllers embedded in
the RK3588 and RK3588S SoCs. Furthermore, RK3588 provides four additional
I2S/PCM/TDM controllers.

This patch series adds the required device tree nodes to support all the above.

Additionally, it enables analog audio support for the Rock 5B SBC, which has
been used to test both audio playback and recording.

Also note the first two patches are not particularly related to I2S, they handle
a few clock issues identified while attempting to fix a DT binding warning.

Changes in v4:
 - Updated patch v3 1/4 adding a missing clock assignment and adjusting the SCMI
   assigned clock rates
 - Added patch v4 2/5 to address an issue reported by Sebastian

Changes in v3:
 - Rebased onto next-20230331 and dropped patches v2 01-06/10 already applied by Rob
 - Ensured DT nodes are in alphabetical order in patch v3 4/4
 - v2: https://lore.kernel.org/lkml/20230321215624.78383-1-cristian.ciocaltea@collabora.com/

Changes in v2:
 - Rebased onto next-20230321 and drop patches 03-08/11 already applied by Mark
 - Replaced patch 01/11 with v2 07/10
 - Reworked patch 02/11 to v2 01-06/10
 - v1: https://lore.kernel.org/lkml/20230315114806.3819515-1-cristian.ciocaltea@collabora.com/
