| /* |
| * 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. |
