1 Hisilicon System Reset Controller
2 ======================================
4 Please also refer to reset.txt in this directory for common reset
5 controller binding usage.
7 The reset controller registers are part of the system-ctl block on
11 - compatible: should be
12 "hisilicon,hi3660-reset"
13 - hisi,rst-syscon: phandle of the reset's syscon.
14 - #reset-cells : Specifies the number of cells needed to encode a
15 reset source. The type shall be a <u32> and the value shall be 2.
17 Cell #1 : offset of the reset assert control
18 register from the syscon register base
19 offset + 4: deassert control register
20 offset + 8: status control register
21 Cell #2 : bit position of the reset in the reset control register
24 iomcu: iomcu@ffd7e000 {
25 compatible = "hisilicon,hi3660-iomcu", "syscon";
26 reg = <0x0 0xffd7e000 0x0 0x1000>;
29 iomcu_rst: iomcu_rst_controller {

31 hisi,rst-syscon = <&iomcu>;
