From 9b7c3495500c31b4acf416c9f866947feab3e230 Mon Sep 17 00:00:00 2001 From: Ye Li Date: Tue, 17 Aug 2021 17:09:20 +0800 Subject: [PATCH] mmc: fsl_esdhc_imx: Fix clock disable issue The SD clock disable is wrapped by MMC_SUPPORTS_TUNING. So it only works when UHS is enabled. However, in SD initialization the power cycle does not depends on UHS. But the power cycle needs disable the SD clock before power down. So this causes a problem when UHS is not enabled. Some cards can't become ready (ACMD14 timeout) due to the clock is enabled during power cycle.
