-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"
- "microchip,sam9x60-hlcdc"
- "microchip,sam9x75-xlcdc"
- - 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
