+MediaTek MT8135 PMIC Wrapper Driver
+
+MediaTek PMIC MFD is interfaced to host controller using SPI interface
+by a proprietary hardware called PMIC wrapper or pwrap.

+This document describes the binding for MT8135 PMIC wrapper.
+
+Required properties in pwrap device node.
+- compatible:"mediatek,mt8135-pwrap"
+- interrupts: IRQ for pwrap in SOC
+- reg: address range for pwrap registers
+- resets: reset bit for pwrap
+- clock: clock frequency selection in SPI bus
+
+Optional properities:
+- pmic: Mediatek PMIC MFD is the child device of pwrap
+  See the following for child node definitions:
+  Documentation/devicetree/bindings/mfd/mt6397.txt
+
+Example:
+	pwrap: pwrap@...0f000 {
+		compatible = "mediatek,mt8135-pwrap";
+		reg = <0 0x1000f000 0 0x1000>,
+			<0 0x11017000 0 0x1000>;
+		reg-names = "pwrap-base", "pwrap-bridge-base";
+		interrupts = <GIC_SPI 128 IRQ_TYPE_LEVEL_HIGH>;
+		resets = <&infrarst MT8135_INFRA_PMIC_WRAP_RST>,
+				<&perirst MT8135_PERI_PWRAP_BRIDGE_SW_RST>;
+		reset-names = "infra-pwrap-rst",
+				"peri-pwrap-bridge-rst";
+		clocks = <&pmicspi_sel>, <&clk26m>;
+		clock-names = "pmicspi-sel", "pmicspi-parent";
+
+		pmic {
+			compatible = "mediatek,mt6397";
+		};
+	};
