While migrating to common clock framework (CCF), found that the FIMD clocks
were pulled down by the CCF.
If CCF finds any clock(s) which has NOT been claimed by any of the
drivers, then such clock(s) are PULLed low by CCF.
By calling clk_prepare_enable() for FIMD clocks fixes the issue.

The PHY controller can choose between ref_pad_clk (XusbXTI-external PLL),
or EXTREFCLK (XXTI-internal clock crystal) to generate the required clock.
Adding the provision for ref_pad_clk here.

The current code in the dwc3 probe effectively disables runtime pm
from ever working because it calls a get() that was never put() until

Many backlights need to be explicitly powered. Typically, this is done
with a GPIO. For flexibility, we generalize the power mechanism to a

Many backlights are enabled via GPIO. We can generalize the GPIO to a
