ENGR00223348 EPDC: Unable to enable DISPLAY regulator In the maxim 17135 driver, the power good is confirmed by the power good GPIO polarity change when comparing the status at the beginning of driver probe and display regulator enabled. However, it is not reliable since the initial value of the GPIO is not constant. Normally, it is 1 but it can be 0 after system reset unexpectedly. Now, it is changed to POK bit checking in FAULT register. Signed-off-by: Jack Lee <jack.lee@freescale.com>
