On some systems the sdhci capabilty register is incorrect for one reason or another. The sdhci-caps-mask property specifies which bits in the register are incorrect and should be turned off before using sdhci-caps to turn on bits. The sdhci-caps property specifies which bits should be turned on.

|
|
property corresponds to the bits in the sdhci capabilty register. If the bit
|
|
is on in the mask then the bit is incorrect in the register and should be
|
|
turned off, before applying sdhci-caps.
|
|
- sdhci-caps: The sdhci capabilities register is incorrect. This 64bit
|
