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