On rk3288, for gpio bank 0, the registers which configure pull-up,
iomux, and drive strength don't implement the enable bits in the upper
half of the register, unlike the other gpio configuration registers,
and so the kernel must perform a read-modify-write of the register to
update a particular gpio in that bank.

If hdmi is inserted or removed before android is launched, screen
size is changed and uboot logo is showing on wrong screen position.
For example, screen size is 720x576 in uboot, hdmi is inserted during
kernel is booting, screen size is changed to 1920x1080, logo size
is still 720x576 and shown on left-top.
This case is occurred on box, mid has no problem. So we need to resize
uboot logo to new screen size.

dev_set_name()
When we use of_device_add() to create platform_device and add it to device
hierarchy, the platform_device.name and device's name will point to the same
memory.
Later we use dev_set_name() to change the device's name, it will alloc new
memory to store name and free old device's name. After it, the
platform_device.name will point to an freed memory, access platform_device.name
maybe lead to unpredictable exceptions.
So, we alloc new memory for platform_device.name in of_device_add()

Phy PLL may be unlock under electro-static test. The higher the
electro-static voltage, the more likely the PLL will be lost.
If PLL is unlock and irq is triggered, we will reset registers
to make it lock on correct frequency.
