31 * Various Lenovo models use a TI LP8557 LED backlight controller with its PWM
33 * The Android kernels have a hack in the i915 driver to write a non-standard
34 * panel specific DSI register to set the duty-cycle of the LCD's PWM output.
43 * Multiplying the 2 levels is useful because this will turn off the backlight
46 * But on some models the panel's PWM output defaults to a duty-cycle of
49 * account and the i915 driver must turn off the panel and the backlight
