| * Clock bindings for Axis ARTPEC-6 chip |
| The bindings are based on the clock provider binding in |
| Documentation/devicetree/bindings/clock/clock-bindings.txt |
| There are two external inputs to the main clock controller which should be |
| provided using the common clock bindings. |
| - "sys_refclk": External 50 Mhz oscillator (required) |
| - "i2s_refclk": Alternate audio reference clock (optional). |
| - #clock-cells: Should be <1> |
| See dt-bindings/clock/axis,artpec6-clkctrl.h for the list of valid identifiers. |
| - compatible: Should be "axis,artpec6-clkctrl" |
| - reg: Must contain the base address and length of the system controller |
| - clocks: Must contain a phandle entry for each clock in clock-names |
| - clock-names: Must include the external oscillator ("sys_refclk"). Optional |
| ones are the audio reference clock ("i2s_refclk") and the audio fractional |
| dividers ("frac_clk0" and "frac_clk1"). |
| compatible = "fixed-clock"; |
| clock-frequency = <50000000>; |
