Add support for CCF for Microblaze.
Old binding:
system_timer: system-timer@41c00000 {
clock-frequency = <75000000>;
...
}
New binding:
system_timer: system-timer@41c00000 {
clocks = <&clk_bus>;
...
}
Both should be supported for a while
Microblaze clock binding:
clocks {
#address-cells = <1>;
#size-cells = <0>;
clk_bus: bus {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "bus";
compatible = "fixed-clock";
reg = <1>;
} ;
clk_cpu: cpu {
#clock-cells = <0>;
clock-frequency = <75000000>;
clock-output-names = "cpu";
compatible = "fixed-clock";
reg = <0>;
} ;
} ;
