31 * Various Lenovo models use a TI LP8557 LED backlight controller with its PWM
32 * input connected to a PWM output coming from the LCD panel's controller.
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.
35 *
36 * To avoid having to have a similar hack in the mainline kernel program the
37 * LP8557 to directly set the level and use the lp855x_bl driver for control.
38 *
39 * The LP8557 can either be configured to multiply its PWM input and
40 * the I2C register set level (requiring both to be at 100% for 100% output);
41 * or to only take the I2C register set level into account.
42 *
43 * Multiplying the 2 levels is useful because this will turn off the backlight
44 * when the panel goes off and turns off its PWM output.
45 *
46 * But on some models the panel's PWM output defaults to a duty-cycle of
47 * much less then 100%, severely limiting max brightness. In this case
48 * the LP8557 should be configured to only take the I2C register into
49 * account and the i915 driver must turn off the panel and the backlight
50 * separately using e.g. VBT MIPI sequences to turn off the backlight.
