The first patch add documentation about a new devicetree property
The second patch makes the sdhci use the DT binding instead of the caps
register for determining which speed modes are supported by the controller.
This RFC is an alternative to another patch set I sent up.
Zach Brown (2):
mmc: sdhci: dt: Add device tree property sdhci-cap-speed-modes-broken
mmc: sdhci: Ignore capability register when it comes to speeds and use
DT binding instead when sdhci-cap-speed-modes-broken is set.
