+Specifying reset lines connected to IP modules
+==============================================
+
+The reset controller(mtk-reset) manages various reset sources. Those device nodes should
+specify the reset line on the rstc in their resets property, containing a phandle to the
+rstc device node and a RESET_INDEX specifying which module to reset, as described in
+reset.txt.
+
+For MediaTek SoC, RESET_INDEX is reset bit defined in INFRACFG or PERICFG registers.
+
+example:
+pwrap: pwrap at 1000f000 {
+ compatible = "mediatek,mt8135-pwrap";
+ reg = <0 0x1000f000 0 0x1000>,
+ <0 0x11017000 0 0x1000>;
+ reg-names = "pwrap-base",
+ "pwrap-bridge-base";
+ resets = <&infrarst 7>, <&perirst 34>;
+ reset-names = "infrarst", "perirst";
+ };
+};You have an extraneous '};' here. Arnd
