These should be named "sram" & "cfg". 138c2ecf20Sopenharmony_ci- clocks Clock for co-processor (See: ../clock/clock-bindings.txt) 148c2ecf20Sopenharmony_ci- clock-names Contains the corresponding name for the clock. This 158c2ecf20Sopenharmony_ci should be named "main". 168c2ecf20Sopenharmony_ci 178c2ecf20Sopenharmony_ciSubnodes 188c2ecf20Sopenharmony_ci-------- 198c2ecf20Sopenharmony_ci 208c2ecf20Sopenharmony_ciSubnodes of the SCP represent rpmsg devices. The names of the devices are not 218c2ecf20Sopenharmony_ciimportant. The properties of these nodes are defined by the individual bindings 228c2ecf20Sopenharmony_cifor the rpmsg devices - but must contain the following property: 238c2ecf20Sopenharmony_ci 248c2ecf20Sopenharmony_ci- mtk,rpmsg-name Contains the name for the rpmsg device. Used to match 258c2ecf20Sopenharmony_ci the subnode to rpmsg device announced by SCP. 268c2ecf20Sopenharmony_ci 278c2ecf20Sopenharmony_ciExample: 288c2ecf20Sopenharmony_ci 298c2ecf20Sopenharmony_ci scp: scp@10500000 { 308c2ecf20Sopenharmony_ci compatible = "mediatek,mt8183-scp"; 318c2ecf20Sopenharmony_ci reg = <0 0x10500000 0 0x80000>, 328c2ecf20Sopenharmony_ci <0 0x105c0000 0 0x5000>; 338c2ecf20Sopenharmony_ci reg-names = "sram", "cfg"; 348c2ecf20Sopenharmony_ci clocks = <&infracfg CLK_INFRA_SCPSYS>; 358c2ecf20Sopenharmony_ci clock-names = "main"; 368c2ecf20Sopenharmony_ci }; 37
