-TI SysCon Reset Controller
-=======================
-
-Almost all SoCs have hardware modules that require reset control in addition
-to clock and power control for their functionality. The reset control is
-typically provided by means of memory-mapped I/O registers. These registers are
-sometimes a part of a larger register space region implementing various
-functionalities. This register range is best represented as a syscon node to
-allow multiple entities to access their relevant registers in the common
-register space.
-
-A SysCon Reset Controller node defines a device that uses a syscon node
-and provides reset management functionality for various hardware modules
-present on the SoC.
-
-SysCon Reset Controller Node
-============================
-Each of the reset provider/controller nodes should be a child of a syscon
-node and have the following properties.
-
-Required properties:
---------------------
- - compatible		: Should be,
-			    "ti,k2e-pscrst"
-			    "ti,k2l-pscrst"
-			    "ti,k2hk-pscrst"
-			    "ti,syscon-reset"
- - #reset-cells		: Should be 1. Please see the reset consumer node below
-			  for usage details
- - ti,reset-bits	: Contains the reset control register information
-			  Should contain 7 cells for each reset exposed to
-			  consumers, defined as:
-			    Cell #1 : offset of the reset assert control
-			              register from the syscon register base
-			    Cell #2 : bit position of the reset in the reset
-			              assert control register
-			    Cell #3 : offset of the reset deassert control
-			              register from the syscon register base
-			    Cell #4 : bit position of the reset in the reset
-			              deassert control register
-			    Cell #5 : offset of the reset status register
-			              from the syscon register base
-			    Cell #6 : bit position of the reset in the
-			              reset status register
-			    Cell #7 : Flags used to control reset behavior,
-			              available flags defined in the DT include
-			              file <dt-bindings/reset/ti-syscon.h>
-
-SysCon Reset Consumer Nodes
-===========================
-Each of the reset consumer nodes should have the following properties,
-in addition to their own properties.
-
-Required properties:
---------------------
- - resets	: A phandle to the reset controller node and an index number
-		  to a reset specifier as defined above.
-
-Please also refer to Documentation/devicetree/bindings/reset/reset.txt for
-common reset controller usage by consumers.
-
-Example:
---------
-The following example demonstrates a syscon node, the reset controller node
-using the syscon node, and a consumer (a DSP device) on the TI Keystone 2
-66AK2E SoC.
-
-/ {
-	soc {
-		psc: power-sleep-controller@2350000 {
-			compatible = "syscon", "simple-mfd";
-			reg = <0x02350000 0x1000>;
-
-			pscrst: reset-controller {
-				compatible = "ti,k2e-pscrst", "ti,syscon-reset";
-				#reset-cells = <1>;
-
-				ti,reset-bits = <
-					0xa3c 8 0xa3c 8 0x83c 8 (ASSERT_CLEAR | DEASSERT_SET   | STATUS_CLEAR) /* 0: dsp0 */
-					0xa40 5 0xa44 3 0     0 (ASSERT_SET   | DEASSERT_CLEAR | STATUS_NONE)  /* 1: example */
-				>;
-			};
-		};
-
-		dsp0: dsp0 {
-			...
-			resets = <&pscrst 0>;
-			...
-		};
-	};
-};
