The mtk-sd silicon has integrated card-detect logic that is enabled on the MT7621. The circuit is phased out on newer hardware so we should be careful to only enabled it on hardware known to support it. This a new "use_internal_cd" flag in struct mtk_mmc_compatible. If the sdhci isn't marked non-removable and doesn't have a cd-gpio configured, and if use_internal_cd is set, then assume the internal cd logic should be used as recommended by Documentation/devicetree/bindings/mmc/mmc.txt Signed-off-by: NeilBrown <neil@brown.name> Reviewed-by: Chaotian Jing <chaotian.jing@mediatek.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> |
