From ec1e5d703e4a75fb19e99a92d20b4b70861bf483 Mon Sep 17 00:00:00 2001 From: Dinh Nguyen Date: Mon, 17 Feb 2014 20:31:01 -0600 Subject: [PATCH] mmc: dw_mmc: Add support for SOCFPGA's platform specific implementation Like the rockchip, Altera's SOCFPGA platform specific implementation of the dw_mmc driver requires using the HOLD register for SD commands. This patch renames dw_mci_rockchip_prepare_command to dw_mci_pltfm_prepare_command so that SOCFPGA and Rockchip can use it.
