Subject: [PATCH v2 0/2] mmc: Allow speed modes to be adjusted dynamically

During board verification, there is a need to test the various supported
eMMC/SD speed modes.  However, since the framework chooses the best mode
supported by the card and the host controller's caps, this currently
necessitates changing the devicetree for every iteration.  This series
provides a way to adjust speed modes dynamically via debugfs.

Changes in v2:
- Replace module parameter with a debugfs file.
- Add patch to move mmc_select_card_type().
- Link to v1: https://lore.kernel.org/r/20220623080009.1775574-1-vincent.whitchurch@axis.com/
