From 50dfe70fe9e216cf356830194630f9a39e498d76 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Tue, 22 Sep 2009 16:45:14 -0700 Subject: 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.
