From 55cd65e48b62c6f08edbb93d5cadf96e876ebcc2 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Tue, 30 Aug 2011 13:17:16 -0600 Subject: mmc: sdhci-tegra: Add 8-bit support to device tree binding. The previous patch which implemented a DT binding for sdhci-tegra did not allow all platform data fields to be initialized from DT. The following were missing: is_8bit: Implemented by this patch. pm_flags: Not implemented yet. There are no mainline users of this field. I'm not quite sure what it's for, and hence how to represent this in DT; the value ends up being assigned to host->mmc->pm_caps. While we're at it, fix the binding documentation to refer to "SD/MMC" instead of "eSDHC", since that's the correct name; "eSDHC" was cut/paste from the Freescale binding docs.
