From d39b1b2abf9fcae3001b868186faa1ae889aecf5 Mon Sep 17 00:00:00 2001 From: Shawn Lin Date: Thu, 5 Apr 2018 18:31:42 +0800 Subject: [PATCH] mmc: dw_mmc: fix misleading comment in dw_mci_rk3288_set_ios DDR52 with 8-bit mode should be handled in a different way when requesting ciu_clk. However DDR50 is used for SDMMC/SDIO and could never be possible with 8-bit mode. It's trival but misleading.
