   6 Required properties:
   7 - compatible: "ti,tps65217"
   8 - reg: I2C slave address
   9 - backlight: node for specifying WLED1 and WLED2 lines in TPS65217
  10 - isel: selection bit, valid values: 1 for ISEL1 (low-level) and 2 for ISEL2 (high-level)
  11 - fdim: PWM dimming frequency, valid values: 100, 200, 500, 1000
  12 - default-brightness: valid values: 0-100
