Microchip PIC32 Clock Controller Binding |
|
---------------------------------------- |
|
Microchip clock controller is consists of few oscillators, PLL, multiplexer |
|
and few divider modules. |
|
|
|
This binding uses common clock bindings. |
|
[1] Documentation/devicetree/bindings/clock/clock-bindings.txt |
|
|
|
Required properties: |
|
- compatible: shall be "microchip,pic32mzda-clk". |
|
- reg: shall contain base address and length of clock registers. |
|
- #clock-cells: shall be 1. |
|
|
|
Optional properties: |
|
- microchip,pic32mzda-sosc: shall be added only if platform has |
|
secondary oscillator connected. |
|
|
|
Example: |
|
rootclk: clock-controller@1f801200 { |
|
compatible = "microchip,pic32mzda-clk"; |
|
reg = <0x1f801200 0x200>; |
|
#clock-cells = <1>; |
|
/* optional */ |
|
microchip,pic32mzda-sosc; |
|
}; |
|
|
|
|
|
The clock consumer shall specify the desired clock-output of the clock |
|
controller (as defined in [2]) by specifying output-id in its "clock" |
|
phandle cell. |
|
[2] include/dt-bindings/clock/microchip,pic32-clock.h |
|
|
|
For example for UART2: |
|
uart2: serial@2 { |
|
compatible = "microchip,pic32mzda-uart"; |
|
reg = <>; |
|
interrupts = <>; |
|
clocks = <&rootclk PB2CLK>; |
|
};
