Please keep the old strings around for compatibility.
Why are these even changing? The commit message should say why.
Have send [RFC V2:PATCH 0/2] add reset-hi3660
Not touching this file any more.
Only handle hi3660.
But hi6220 can directly use the driver.
Only need list reset info to hi6220.dts, same as hi3660.
Like
+ iomcu_rst: iomcu_rst_controller {
+ compatible = "hisilicon,hi3660-reset";
+ #reset-cells = <1>;
+ hisi,rst-syscon = <&iomcu>;
+ hisi,reset-bits = <0x20 0x8 /* 0: i2c0 */
+ 0x20 0x10 /* 1: i2c1 */
+ 0x20 0x20 /* 2: i2c2 */
+ 0x20 0x8000000>; /* 3: i2c6 */
+ };
Thanks
