From 7541ca98477862e2e9988c6c2ceadbdccefa9d77 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Tue, 12 Jun 2012 22:56:09 +0200 Subject: [PATCH] mmc: sh_mmcif: Support MMC_SLEEP_AWAKE command The MMC_SLEEP_AWAKE and SD_IO_SEND_OP_COND commands share the same opcode. SD_IO_SEND_OP_COND isn't supported by the SH MMCIF, but MMC_SLEEP_AWAKE is. Discriminate between the two commands using the command flags, and reject SD_IO_SEND_OP_COND only.
