From: Dinh Nguyen Date: Tue, 18 Feb 2014 02:31:01 +0000 (-0600) Subject: mmc: dw_mmc: Add support for SOCFPGA's platform specific implementation X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ec1e5d703e4a75fb19e99a92d20b4b70861bf483;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git 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.
