-CSR SiRFSoC Reset Controller
-======================================
-
-Please also refer to reset.txt in this directory for common reset
-controller binding usage.
-
-Required properties:
-- compatible: Should be "sirf,prima2-rstc" or "sirf,marco-rstc"
-- reg: should be register base and length as documented in the
- datasheet
-- #reset-cells: 1, see below
-
-example:
-
-rstc: reset-controller@88010000 {
- compatible = "sirf,prima2-rstc";
- reg = <0x88010000 0x1000>;
- #reset-cells = <1>;
-};
-
-Specifying reset lines connected to IP modules
-==============================================
-
-The reset controller(rstc) manages various reset sources. This module provides
-reset signals for most blocks in system. Those device nodes should specify the
-reset line on the rstc in their resets property, containing a phandle to the
-rstc device node and a RESET_INDEX specifying which module to reset, as described
-in reset.txt.
-
-For SiRFSoC, RESET_INDEX is just reset_bit defined in SW_RST0 and SW_RST1 registers.
-For modules whose rest_bit is in SW_RST0, its RESET_INDEX is 0~31. For modules whose
-rest_bit is in SW_RST1, its RESET_INDEX is 32~63.
-
-example:
-
-vpp@90020000 {
- compatible = "sirf,prima2-vpp";
- reg = <0x90020000 0x10000>;
- interrupts = <31>;
- clocks = <&clks 35>;
- resets = <&rstc 6>;
-};
