+Hisilicon System Reset Controller
+======================================
+
+Please also refer to reset.txt in this directory for common reset
+controller binding usage.
+
+The reset controller registers are part of the system-ctl block on
+hi3660 SoC.
+
+Required properties:
+- compatible: should be
+ "hisilicon,hi3660-reset"
+- #reset-cells: 1, see below
+- hisi,rst-syscon: phandle of the reset's syscon.
+- hisi,reset-bits: Contains the reset control register information
+ Should contain 2 cells for each reset exposed to
+ consumers, defined as:
+ Cell #1 : offset from the syscon register base
+ Cell #2 : bits position of the control register
+
+Example:
+ iomcu: iomcu@ffd7e000 {
+ compatible = "hisilicon,hi3660-iomcu", "syscon";
+ reg = <0x0 0xffd7e000 0x0 0x1000>;
+ };
+
+ iomcu_rst: iomcu_rst_controller {
This should be
iomcu_rst: reset-controller {
By the way, could I keep the original name?
Since there will be build error if several nodes use the same name.
like:
- iomcu_rst: iomcu_rst_controller {
+ iomcu_rst: reset-controller {
- crg_rst: crg_rst_controller {
+ crg_rst: reset-controller {
Thanks
