From 434936c3486c2b5a9d2011da633baa3096684b50 Mon Sep 17 00:00:00 2001 From: Peter Griffin Date: Wed, 9 Jul 2014 16:07:33 +0100 Subject: [PATCH] mmc: sdhci-st: ST Microelectronics SDHCI binding documentation. This patch adds the device tree binding documentation for the ST SDHCI driver. It documents the differences between the core properties described by mmc.txt and the properties used by the sdhci-st driver.
