DWC_mipi_dsi_host can be configured to send the low-power (LP)
commands during the HS video mode transmission. To enable this
feature, set the lp_cmd_en bit of the VID_MODE_CFG register to 1.
In this case, it is necessary to calculate the time available,
in bytes, to transmit a command in LP mode to Horizontal Front Porch (HFP),
Vertical Sync Active (VSA), Vertical Back Porch (VBP), and
Vertical Front Porch (VFP) regions.
Bits 8 to 13 of the VID_MODE_CFG register indicates if DWC_mipi_dsi_host
can go to LP when in idle. If the lp_cmd_en bit is set (1'b1) and
non-video packets are in queue, DWC_mipi_dsi_host ignores the LP
configuration and transmits LP commands, even if it is not allowed
to enter LP in a specific region. After the LP commands transmission,
DWC_mipi_dsi_host remains in LP until a sync event occurs.
If the lp_cmd_en bit of the VID_MODE_CFG register is 0, the commands
are sent in high-speed in Video Mode. In this case, the DWC_mipi_dsi_host
automatically determines the area where each command can be sent and no
programming or calculation is required.

(cherry picked from commit e839508163)
MIPI DSI devices are inherently aware of their host because they share a
parent-child hierarchy in the device tree.
Non-DSI drivers that create DSI device don't have this data. In order to
get this information, they require to a phandle to the DSI host in the
device tree.
Maintain a list of all the DSI hosts that are currently registered. This
list will be used to find the struct mipi_dsi_host corresponding to the
device tree node passed to of_find_mipi_dsi_host_by_node().

(cherry picked from commit 509e42ce04)
Add a device name field in struct mipi_dsi_device. This name is not the
same as the device name (which is of the format "hostname.reg"). When
the device is created via DT, this name is set to the modalias string.
In the non-DT case, the driver creating the DSI device provides the
name by populating a field in struct mipi_dsi_device_info.
Matching for DT case would be as it was before. For the non-DT case, we
compare the device and driver names. Other buses (like I2C/SPI) perform
a non-DT match by comparing the device name and entries in the driver's
id_table. Such a mechanism isn't used for the DSI bus.

(cherry picked from commit bf4363ce3a)
Use mipi_dsi_device_register_full() for device creation. This takes in
a struct mipi_dsi_device_info as a template to populate the DSI device
information.
The reason to introduce this is to have a way to create DSI devices not
available via DT. Drivers that want to create a DSI device can populate
a struct mipi_dsi_device_info and call this function. For DSI devices
available via DT, of_mipi_dsi_device_add() is used as before, but this
now calls mipi_dsi_device_register_full() internally.
