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()

If PLL is unlock and irq is triggered, we will reset registers

put this into box dts.
Meanwhile, that PWM configure will break the normal PWM driver.

We are assuming that PWM need use the property, we can support the
SPI interrupts for PWM.
At the moment, we can find the remotectl pwm is needed on box.
We can add the property for all PWMs. AFAIK, the pwm driver don't use it
but the drivers/input/remotectl/rockchip_pwm_remotectl.c

Under certain circumstances, we want to disable some input
devices from userspace. In particular, when we detect that the lid of a
laptop is closed, we want to be able to disable touchpad and
touchscreen to avoid bogus input.
To facilitate this, we introduce the "inhibited" sysfs property for
input devices. Using this property, userspace can tell a driver that the
events it can provide are not currently of interest and should be
ignored. We provide hooks so that the driver can take additional
actions, such as powering down the device.
We deliberately keep this limited to input devices for now to keep the
implementation as straightforward as possible.
(cherry-pick from: https://chromium-review.googlesource.com/207989)

commit 3e9b2bae83 upstream
These functions are being open-coded in 3 different places in the driver
core, and other driver subsystems will want to start doing this as well,
so move it to the sysfs core to keep it all in one place, where we know
it is written properly.
