This DW-MMC variant is not actually compatible with "samsung,exynos7-dw-mshc-smu", and requires an additional quirk to handle very short data transfers, typically used by SDIO cards. Update the compatible string to "samsung,exynos7885-dw-mshc-smu" to reflect this fact. --- arch/arm64/boot/dts/exynos/exynos7885.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/exynos/exynos7885.dtsi b/arch/arm64/boot/dts/exynos/exynos7885.dtsi index 23c2e0bb0..b0addb0b3 100644 --- a/arch/arm64/boot/dts/exynos/exynos7885.dtsi +++ b/arch/arm64/boot/dts/exynos/exynos7885.dtsi @@ -294,7 +294,7 @@ pmu_system_controller: system-controller@11c80000 { }; mmc_0: mmc@13500000 { - compatible = "samsung,exynos7-dw-mshc-smu"; + compatible = "samsung,exynos7885-dw-mshc-smu"; reg = <0x13500000 0x2000>; interrupts = <GIC_SPI 146 IRQ_TYPE_LEVEL_HIGH>; #address-cells = <1>; -- 2.38.3
