From 81dce1490e28439c3cd8a8650b862a712f3061ba Mon Sep 17 00:00:00 2001 From: Haibo Chen haibo.chen@nxp.com Date: Thu, 4 May 2023 19:22:22 +0800 Subject: [PATCH] mmc: sdhci-esdhc-imx: make "no-mmc-hs400" works
After commit 1ed5c3b22fc7 ("mmc: sdhci-esdhc-imx: Propagate ESDHC_FLAG_HS400* only on 8bit bus"), the property "no-mmc-hs400" from device tree file do not work any more. This patch reorder the code, which can avoid the warning message "drop HS400 support since no 8-bit bus" and also make the property "no-mmc-hs400" from dts file works.
