+Subject: [PATCH] arm64: dts: marvell: fix sdhci1 controller for gl-mv1000
+
+GL-MV1000 external SD controller was broken by a recent kernel update
+due to a mistake in Device Tree: "regulator-gpio" was defined without
+required "gpios" property.
+
+Since "no-1-8-v" property is also defined for this controller
+a switchable vqmmc-supply regulator performs no function - a fixed 3.3V
+IO voltage will always be used.
+
+This regulator definition was probably added by mistake from a Device
+Tree from another device.
+
+Remove incomplete vcc_sd_reg1 regulator definition to fix this issue.
+
