Subject: [PATCH v2 0/3] mmc: renesas_sdhi: reset via reset controller
Date: Mon, 15 Mar 2021 15:59:35 +0100 [thread overview]
Message-ID: <20210315145938.58565-1-wsa+renesas@sang-engineering.com> (raw)
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
