      1Pistachio Reset Controller
      2=============================================================================
      3
      4This binding describes a reset controller device that is used to enable and
      5disable individual IP blocks within the Pistachio SoC using "soft reset"
      6control bits found in the Pistachio SoC top level registers.
      7
      8The actual action taken when soft reset is asserted is hardware dependent.
      9However, when asserted it may not be possible to access the hardware's
     10registers, and following an assert/deassert sequence the hardware's previous
     11state may no longer be valid.
     12
     13Please refer to Documentation/devicetree/bindings/reset/reset.txt
     14for common reset controller binding usage.
     15
     16Required properties:
     17
     18- compatible: Contains "img,pistachio-reset"
     19
     20- #reset-cells: Contains 1
     21
     22Example:
     23
     24	cr_periph: clk@18148000 {
     25		compatible = "img,pistachio-cr-periph", "syscon", "simple-mfd";
     26		reg = <0x18148000 0x1000>;
     27		clocks = <&clk_periph PERIPH_CLK_SYS>;
     28		clock-names = "sys";
     29		#clock-cells = <1>;
     30
     31		pistachio_reset: reset-controller {
     32			compatible = "img,pistachio-reset";
     33			#reset-cells = <1>;
     34		};
     35	};
     36
     37Specifying reset control of devices
     38=======================================
     39
     40Device nodes should specify the reset channel required in their "resets"
     41property, containing a phandle to the pistachio reset device node and an
     42index specifying which reset to use, as described in
     43Documentation/devicetree/bindings/reset/reset.txt.
     44
     45Example:
     46
     47	spdif_out: spdif-out@18100d00 {
     48		...
     49		resets = <&pistachio_reset PISTACHIO_RESET_SPDIF_OUT>;
     50		reset-names = "rst";
     51		...
     52	};
     53
