    1 Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
    2 
    3 Required properties:
    4  - compatible: value should be one of the following:
    5    "atmel,at91sam9n12-hlcdc"
    6    "atmel,at91sam9x5-hlcdc"
    7    "atmel,sama5d2-hlcdc"
    8    "atmel,sama5d3-hlcdc"
    9    "atmel,sama5d4-hlcdc"
   10    "microchip,sam9x60-hlcdc"
   11  - reg: base address and size of the HLCDC device registers.
   12  - clock-names: the name of the 3 clocks requested by the HLCDC device.
   13    Should contain "periph_clk", "sys_clk" and "slow_clk".
   14  - clocks: should contain the 3 clocks requested by the HLCDC device.
   15  - interrupts: should contain the description of the HLCDC interrupt line
   16 
   17 The HLCDC IP exposes two subdevices:
   18  - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
   19  - a Display Controller: see ../display/atmel/hlcdc-dc.txt
   20 
   21 Example:
   22
