Subject: [PATCH 0/2] mmc: renesas_sdhi: reset via reset controller
Date: Tue,  9 Mar 2021 10:23:30 +0100	[thread overview]
Message-ID: <20210309092332.30705-1-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.

Changes since RFC v2 (thanks Geert for the review!):

* use devm_reset_control_get_optional_exclusive()
* select RESET_CONTROLLER
* given reason in commit message of patch 2

Tested on a Salvator-XS with a Renesas R-Car M3-N.

Shimoda-san: I think we need to get this series upstream first. On top
of this, I will work on the better irq_mask handling.
