   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    "microchip,sam9x75-xlcdc"
  12  - reg: base address and size of the HLCDC device registers.
  13  - clock-names: the name of the 3 clocks requested by the HLCDC device.
  14    Should contain "periph_clk", "sys_clk" and "slow_clk".
  15  - clocks: should contain the 3 clocks requested by the HLCDC device.
  16  - interrupts: should contain the description of the HLCDC interrupt line
  17
  18 The HLCDC IP exposes two subdevices:
  19  - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
  20  - a Display Controller: see ../display/atmel/hlcdc-dc.txt
