+STMicroelectronics Remote Processor
+-----------------------------------
+
+This binding provides support for adjunct processors found on ST SoCs.
+
+The remote processors can be controlled from the bootloader or the primary OS.
+If the bootloader starts a remote processor processor the primary OS must detect
+its state and act accordingly.
+
+Required properties:
+- compatible Should be one of:
+ "st,st231-rproc"
+ "st,st40-rproc"
+- reg Size and length of reserved co-processor memory
+- resets Reset lines (See: ../reset/reset.txt)
+- reset-names Must be "sw_reset" and "pwr_reset"
+- clocks Clock for co-processor (See: ../clock/clock-bindings.txt)
+- clock-names Must be "rproc_clk"
+- clock-frequency Clock frequency to set co-processor at if the bootloader
+ hasn't already done so
+- st,syscfg-boot The register that holds the boot vector for the co-processor
+
+Example:
+
+ st231-audio@bae00000 {
+ compatible = "st,st231-rproc";
+ reg = <0xbae00000 0x01000000>;
+ reg-names = "rproc_mem";
+ resets = <&softreset STIH407_ST231_AUD_SOFTRESET>;
+ reset-names = "sw_reset";
+ clocks = <&clk_s_c0_flexgen CLK_ST231_AUD_0>;
+ clock-names = "rproc_clk";
+ clock-frequency = <600000000>;
+ st,syscfg-boot = <&syscfg_core 0x228>;
+ };
