Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: value should be one of the following:
|
||
|
|
"atmel,at91sam9n12-hlcdc"
|
||
|
|
"atmel,at91sam9x5-hlcdc"
|
||
|
|
"atmel,sama5d2-hlcdc"
|
||
|
|
"atmel,sama5d3-hlcdc"
|
||
|
|
"atmel,sama5d4-hlcdc"
|
||
|
|
- reg: base address and size of the HLCDC device registers.
|
||
|
|
- clock-names: the name of the 3 clocks requested by the HLCDC device.
|
||
|
|
Should contain "periph_clk", "sys_clk" and "slow_clk".
|
||
|
|
- clocks: should contain the 3 clocks requested by the HLCDC device.
|
||
|
|
- interrupts: should contain the description of the HLCDC interrupt line
|
||
|
|
|
||
|
|
The HLCDC IP exposes two subdevices:
|
||
|
|
- a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
|
||
|
|
- a Display Controller: see ../display/atmel-hlcdc-dc.txt
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|

|

|
|
interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
|

|
|
status = "disabled";
