+STMicroelectronics Co-Processor Bindings
+
+
+This binding provides support for adjunct processors found on ST SoCs.
+
+Co-processors can be controlled from the bootloader or the primary OS. If
+the bootloader starts a co-processor, the primary OS must detect its state
+and act accordingly.
+
+Required properties:
+- compatible   Should be one of:
+   "st,st231-rproc"
+   "st,st40-rproc"
+- memory-regionReserved memory (See: 
../reserved-memory/reserved-memory.txt)
+- 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-frequency  Clock frequency to set co-processor at if the bootloader
+   hasn't already done so
+- st,syscfgSystem configuration register which holds the boot 
vector
+   for the co-processor
+   1st cell: Phandle to syscon block
+   2nd cell: Boot vector register offset
+
+Example:
+
+   audio_reserved: rproc@4200 {
+   compatible = "shared-dma-pool";
+   reg = <0x4200 0x0100>;
+   no-map;
+   };
+
+   st231-audio {
+   compatible  = "st,st231-rproc";
+   memory-region   = <&audio_reserved>;
+   resets  = <&softreset STIH407_ST231_AUD_SOFTRESET>;
+   reset-names = "sw_reset";
+   clocks  = <&clk_s_c0_flexgen CLK_ST231_AUD_0>;
+   clock-frequency = <6>;
+   st,syscfg   = <&syscfg_core 0x228>;
