[v2,0/3] mmc: renesas_sdhi: reset via reset controller

Message

Wolfram Sang March 15, 2021, 2:59 p.m. UTC

This series enables SDHI to be reset via a reset controller.
Please let me know about your (and BSP team's) thoughts.
The series is based on mmc/next and tested on Salvator-XS with R-Car H3
ES2.0 with what I think I can do locally here.

Changes since v1:
* Niklas tag added to patch 1 (thanks!)
* new patch 2 to factor out SCC reset and make intentions clearer
  (thanks to Shimoda-san for the review!)
* patch 3 re-inits now the SD clock again after the hard reset

Wolfram Sang (3):
  mmc: tmio: abort DMA before reset
  mmc: renesas_sdhi: break SCC reset into own function
  mmc: renesas_sdhi: do hard reset if possible

Also, I tested on R-Car H3 ES3.0 and I didn't observe any regression.
So,
