Fix the maximum brightness being much too low on the Yoga Tab 3 Pro. The LP8557 backlight controller 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 the YT3-X90F 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 backlight separately using a VBT MIPI sequence to turn off the backlight.
