+ST Voltage regulator for FlashSS vsense
+
+This documents the voltage regulator driver which manages the vsense inside the ST flash
+sub-system that is used for configuring MMC, NAND, SPI voltages.
+
+Required properties:
+- compatible: Can be "st,vqmmc", "st,vnand" or "st,vspi" because it is shared
+ among these devices inside the ST FlashSS.
+- regulator-name: Regulator name.
+- reg: The vsense top config base address in the flashSS hardware.
+
+Any property defined as part of the core regulator binding, in
+Documentation/devicetree/bindings/regulator/regulator.txt can also be used.
+
+Example:
+
+vqmmc_reg: voltage-regulator {
+ compatible = "st,vqmmc";
+ regulator-name = "vqmmc0";
+ /* Control register for the VSENSE Module */
+ reg = <0x9061004 0x4>;
+ status = "disabled";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <3300000>;
+ regulator-always-on;
+};
+
+mmc0: sdhci@09060000 {
+ compatible = "st,sdhci-stih407", "st,sdhci";
+ status = "disabled";
+ reg = <0x09060000 0x7ff>, <0x9061008 0x20>;
+ reg-names = "mmc", "top-mmc-delay";
+ interrupts = <GIC_SPI 92 IRQ_TYPE_NONE>;
+ interrupt-names = "mmcirq";
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_mmc0>;
+ clock-names = "mmc";
+ clocks = <&clk_s_c0_flexgen CLK_MMC_0>;
+ bus-width = <8>;
+ non-removable;
+ vqmmc-supply = <&vqmmc_reg>;
+};
+
This patch adds the DT doc for the flashss regulator driver which is found in stih407 based silicon.
