Using new reset-hi6220 with common reset.c
And keeps the same reset define
dts hi6220.c should be updated with new node sys_ctrl_rst
Solving potential issue of sys_ctrl can not be used as clock and reset
at the same time.
sys_ctrl: sys_ctrl@f7030000 {
compatible = "hisilicon,hi6220-sysctrl", "syscon";
reg = <0x0 0xf7030000 0x0 0x2000>;
#clock-cells = <1>;
};
sys_ctrl_rst: sys_rst_controller {
compatible = "hisilicon,hi6220-reset-sysctrl";
#reset-cells = <1>;
hisi,rst-syscon = <&sys_ctrl>;
};
uart1: serial@..... {
...
resets = <&sys_ctrl_rst PERIPH_RSTEN3_UART1>;
...
};
