I think you need to change the 'unit-address' now, i.e. the @10001030
value above no longer matches any reg property. You could just
remove that part.
+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.
