Subject: [PATCH 4/7] powerpc: Introduce and document sdhci,wp-inverted property for eSDHC
Date: Fri, 7 Aug 2009 23:58:10 +0400 [thread overview]
Message-ID: <20090807195810.GD2735@oksana.dev.rtsoft.ru> (raw)
In-Reply-To: <20090807195724.GA24020@oksana.dev.rtsoft.ru>
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.
