   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,sama5d3-hlcdc"
   6  - reg: base address and size of the HLCDC device registers.
   7  - clock-names: the name of the 3 clocks requested by the HLCDC device.
   8    Should contain "periph_clk", "sys_clk" and "slow_clk".
   9  - clocks: should contain the 3 clocks requested by the HLCDC device.
  10  - interrupts: should contain the description of the HLCDC interrupt line
  11
  12 The HLCDC IP exposes two subdevices:
  13  - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
  14  - a Display Controller: see ../drm/atmel-hlcdc-dc.txt
