For various reasons the sdhci caps register can be incorrect. This patch set
introduces a general way to correct the bits when they are read to accurately
reflect the capabilties of the controller/board combo.
The first patch creates sdhci-caps and sdhci-caps-mask dt properties that
combined represent the correction to the sdhci caps register.
The second patch uses the new dt properties to correct the caps from the
register as they read during __sdhci_read_caps.
Changes from RFC:
* /s/registers/register
* Moved sdhci dt properties into new documentation file sdhci.txt
v2:
* Fixed style issue, all branches of 'if' should have {}
Zach Brown (2):
mmc: sdhci: dt: Add device tree properties sdhci-caps and
sdhci-caps-mask
mmc: sdhci: Use sdhci-caps-mask and sdhci-caps to change the caps read
during __sdhci_read_caps
