+Mediatek SPMI Controller
+
+This document describes the binding for the MediaTek SPMI controller.
+
+On MediaTek SoCs the PMIC is connected via SPMI and the controller allows
+for multiple SoCs to control a single SPMI master.
+
+Required properties:
+- compatible : "mediatek,mt6873-spmi".
+- reg-names : must contain:
+ "pmif" - pmif registers
+ "spmimst" - spmi controller registers
+- reg: Must contain an entry for each entry in reg-names.
+- clock-names: Must include the following entries:
+ "pmif_sys_ck": pmif system clock
+ "pmif_tmr_ck": pmif timer clock
+ "spmimst_clk_mux": spmi master clk mux
+- clocks: Must contain an entry for each entry in clock-names.
+
+Example:
+
+ spmi: spmi@10027000 {
+ compatible = "mediatek,mt6873-spmi";
+ reg = <0 0x10027000 0 0x000e00>,
+ <0 0x10029000 0 0x000100>;
+ reg-names = "pmif", "spmimst";
+ clocks = <&infracfg CLK_INFRA_PMIC_AP>,
+ <&infracfg CLK_INFRA_PMIC_TMR>,
+ <&topckgen CLK_TOP_SPMI_MST_SEL>;
+ clock-names = "pmif_sys_ck",
+ "pmif_tmr_ck",
+ "spmimst_clk_mux";
+ };
