From: Luke Wang Date: Wed, 11 Mar 2026 09:50:07 +0000 (+0800) Subject: mmc: sdhci-esdhc-imx: add 1-bit bus width support X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=60ed2f96c9842cd4e85e3229fdc6bec2a0fa9cfa;p=thirdparty%2Fkernel%2Fstable.git mmc: sdhci-esdhc-imx: add 1-bit bus width support Add sdhci_get_property() call to parse common SDHCI DT properties, including "bus-width = <1>" which sets SDHCI_QUIRK_FORCE_1_BIT_DATA quirk for 1-bit data bus width configuration. Remove the duplicate "no-1-8-v" property parsing since sdhci_get_property() already handles it.
