Subject: [PATCH v2 0/2] arm64: dts: amlogic: s4: mmc clock fixups

The patchset aims to address the issue raised here [1] for MMC B.

While checking this issue, I've found that MMC A and C also appear to be
improperly described in this platform's DT. The 2nd change fixes that.

To be on the safe side, the MMC clock should also be assigned on the other
SoCs. More changes will follow once things are sorted out for s4.

Changes in v2:
- Collect Tested-by from Nick
- Fix some typos in the commit description
- Link to v1: https://lore.kernel.org/r/20260113-amlogic-s4-mmc-fixup-v1-0-1ab1fca0fb2f@baylibre.com
