1Microchip PIC32 Clock Controller Binding 2---------------------------------------- 3Microchip clock controller is consists of few oscillators, PLL, multiplexer 4and few divider modules. 5 6This binding uses common clock bindings. 7[1] Documentation/devicetree/bindings/clock/clock-bindings.txt 8 9Required properties: 10- compatible: shall be "microchip,pic32mzda-clk". 11- reg: shall contain base address and length of clock registers. 12- #clock-cells: shall be 1. 13 14Optional properties: 15- microchip,pic32mzda-sosc: shall be added only if platform has 16 secondary oscillator connected. 17 18Example: 19 rootclk: clock-controller@1f801200 { 20 compatible = "microchip,pic32mzda-clk"; 21 reg = <0x1f801200 0x200>; 22 #clock-cells = <1>; 23 /* optional */ 24 microchip,pic32mzda-sosc; 25 }; 26 27 28The clock consumer shall specify the desired clock-output of the clock 29controller (as defined in [2]) by specifying output-id in its "clock" 30phandle cell. 31[2] include/dt-bindings/clock/microchip,pic32-clock.h 32 33For example for UART2: 34uart2: serial@2 { 35 compatible = "microchip,pic32mzda-uart"; 36 reg = <>; 37 interrupts = <>; 38 clocks = <&rootclk PB2CLK>; 39}; 40
