Three operating mode are available to convey the graphical data
to the display:
- Video mode streams over the high-speed link the RGB data and the
associated synchronization signals directly generated by the LCDC.
The streaming starts as soon as the DSI Host and the LCDC are enabled.
This continuous refresh is the best way to interface with a display
without Graphics RAM.
- APB command mode sends commands over the high-speed link for
configuration as it is done using a legacy serial interface (SPI).
The commands are launched using the DSI Host APB interface.
- Adapted command mode is the best way to interface with a display
having its own internal Graphics RAM. The DSI Host captures only
one full frame coming from the LCDC and transforms it into a series
of write commands to update the display Graphics RAM.

In order to enhance the overall robustness of the system, DSI defines
a dedicated EoT packet (EoTp) at the protocol layer for signaling
the end of HS transmission. For backwards compatibility with earlier
DSI systems, the capability of generating and interpreting this EoTp
can be enabled or disabled.

Since msleep is based on jiffies the panel could take longer
than expected. So use msleep for values greater than 20 msec
otherwise usleep_range.

This patch adds a new RGB media bus formats that describe
18-bit samples transferred over an LVDS bus with three
differential data pairs, serialized into 7 time slots,
using standard JEIDA data ordering.

iommu driver probe will register vop pd to power domain control, this pd
will be closed before display driver enable and lead to display black.
so we move vop pd to display driver control.

I found if eDP_AVDD_1V0 and eDP_AVDD_1V8 are not been power at
RK3288, once trying to enable the pclk clock, the kernel would dead.
This patch would try to enable them first.
The eDP_AVDD_1V8 is used for eDP phy, and the eDP_AVDD_1V0 are used
both for eDP phy and controller.

internally according to the specified format configuration and selection.

Sometimes, we would abort suspend work before it finished.
In this case, suspend work would try to resume the part suspended
by correspond resume functions.
But the suspend/resume functions are not matched in rockchip.
When the suspend work is aborted, it would ignored resuming this
part due to can't find correspond resume functions.
So, let's use suspend_late instead of suspend.
