Subject: [PATCH] powerpc: introduce and document sdhci,wp-inverted property for eSDHC
|
|
|
|
eSDHC block in MPC837x SOCs reports inverted write-protect state, soon
|
|
sdhci-of driver will look for sdhci,wp-inverted properties to decide
|
|
whether apply a specific quirk.
|
|
|
|
So, document the property and add it to device tree source files.
