mmc: mtk-sd: improve support for mt7620 variant | expand

Message

Shiji Yang June 19, 2025, 5:35 a.m. UTC

This patchset adds some specific initialization parameters to the
legacy MIPS mt7620 variant to improve the driver stability. These
changes have been tested on MT7620, MT7621 and MT7628. I didn't
notice any negative feedback since it was merged into a popular
Linux distribution OpenWrt. So it's time to upstream it.

Shiji Yang (4):
  mmc: mtk-sd: disable auto CMD23 support for mt7620
  mmc: mtk-sd: add default tuning parameters for mt7620
  mmc: mtk-sd: add default PAD control for mt7620
  mmc: mtk-sd: use default PATCH_BIT register values for mt7620
