1 STMicroelectronics Co-Processor Bindings
2 ----------------------------------------
6 Co-processors can be controlled from the bootloader or the primary OS. If
7 the bootloader starts a co-processor, the primary OS must detect its state
11 - compatible		Should be one of:
12 				"st,st231-rproc"
13 				"st,st40-rproc"
14 - memory-region		Reserved memory (See: ../reserved-memory/reserved-memory.txt)
15 - resets		Reset lines (See: ../reset/reset.txt)
16 - reset-names		Must be "sw_reset" and "pwr_reset"
17 - clocks		Clock for co-processor (See: ../clock/clock-bindings.txt)
18 - clock-frequency	Clock frequency to set co-processor at if the bootloader
20 - st,syscfg		System configuration register which holds the boot vector
21 			for the co-processor
28 		compatible = "shared-dma-pool";
30 		no-map;
33 	st231-audio {
34 		compatible	= "st,st231-rproc";
35 		memory-region	= <&audio_reserved>;
37 		reset-names	= "sw_reset";
39 		clock-frequency	= <600000000>;
