From e58e68d93e7d73e42eac850ff0dafc634bf0d397 Mon Sep 17 00:00:00 2001 From: Weijie Gao Date: Thu, 12 Nov 2020 16:37:07 +0800 Subject: [PATCH] mmc: mtk-sd: assign plat->cfg.f_max with a correct value Currently this driver does not set the value of plat->cfg.f_max, which results in that MMC framework will always run at the lowest frequency. This patch sets plat->cfg.f_max to the maximum allowed frequency, which equals to the source clock frequency.
