Kernel-4.18.0-80.el8_csr,atlas7-car

  • Clock and reset bindings for CSR atlas7

Required properties:

  • compatible: Should be “sirf,atlas7-car”
  • reg: Address and length of the register set
  • #clock-cells: Should be <1>
  • #reset-cells: Should be <1>

The clock consumer should specify the desired clock by having the clock
ID in its “clocks” phandle cell.
The ID list atlas7_clks defined in drivers/clk/sirf/clk-atlas7.c

The reset consumer should specify the desired reset by having the reset
ID in its “reset” phandle cell.
The ID list atlas7_reset_unit defined in drivers/clk/sirf/clk-atlas7.c

Examples: Clock and reset controller node:

car: clock-controller@18620000 {
compatible = “sirf,atlas7-car”;
reg = <0x18620000 0x1000>;
#clock-cells = <1>;
#reset-cells = <1>;
};

Examples: Consumers using clock or reset:

timer@10dc0000 {
compatible = “sirf,macro-tick”;
reg = <0x10dc0000 0x1000>;
clocks = <&car 54>;
interrupts = <0 0 0>,
<0 1 0>,
<0 2 0>,
<0 49 0>,
<0 50 0>,
<0 51 0>;
};

uart1: uart@18020000 {
cell-index = <1>;
compatible = “sirf,macro-uart”;
reg = <0x18020000 0x1000>;
clocks = <&clks 95>;
interrupts = <0 18 0>;
fifosize = <32>;
};

vpp@13110000 {
compatible = “sirf,prima2-vpp”;
reg = <0x13110000 0x10000>;
interrupts = <0 31 0>;
clocks = <&car 85>;
resets = <&car 29>;
};
