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.

Just the same as in Midgard device driver.
This could resolve Defect #170228 and #184427 in RK redmine.
In addition, add err log for the case that alloc_page() returns NULL.

(cherry picked from commit 5abca06c21)
Add regulator driver for the device TI TPS65132 which is single
inductor - dual output power supply device. TPS65132 device is
designed to support general positive/negative driven applications
like TFT display panels.
TPS65132 regulator driver supports to enable/disable and set voltage
on its output.

drm_panel_attach() return EBUSY if panel->connector already set,
which indicate that panel and connector are already bound.
Because the .bind() function might call multiple times, so it is
unnecessary to check its return value.
