The hs_rate and lp_rate may be used by the dsi host for timing
calculations. The tc358775 has a maximum bit rate of 1 Gbps/lane,
tc358765 has maximurate of 800 Mbps per lane.

The tc358775 bridge is pin compatible with earlier tc358765 according to
the tc358774xbg_datasheet_en_20190118.pdf documentation. Compared to the
tc358765, the tc358775 supports a STBY GPIO and higher data rates.
The tc358765 has a register bit for video event mode vs video pulse mode.
We must set it to video event mode for the LCD output to work, and on the
tc358775, this bit no longer exists.
Looks like the registers seem to match otherwise based on a quick glance
comparing the defines to the earlier Android kernel tc358765 driver.

The current code assumes the data-lanes property is configured on the
DSI host side instead of the bridge side, and assumes DSI host endpoint 1.
Let's standardize on what the other bridge drivers are doing and parse the
data-lanes property for the bridge. Only if data-lanes property is not found,
let's be nice and also check the DSI host for old dtb in use and warn.
And as Dmitry pointed out, the lanes for the host and the bridge may be
different because the lanes may be swapped on the host side.

The bridge always uses 24bpp internally. Therefore, for jeida-18
mapping we need to discard the lowest two bits for each channel and thus
starting with LV_[RGB]2. jeida-24 has the same mapping but uses four
lanes instead of three, with the forth pair transmitting the lowest two
bits of each channel. Thus, the mapping between jeida-18 and jeida-24
is actually the same, except that one channel is turned off (by
selecting the RGB666 format in VPCTRL).
While at it, remove the bogus comment about the hardware default because
the default is overwritten in any case.
Tested with a jeida-18 display (Evervision VGG644804).

Stop relying on the dev_priv local variable in the DSI register
macros. Pass struct intel_display pointer to the macros. Move the MIPI
DSI MMIO base selection to a different level, passing it to _MMIO_MIPI()
and doing the addition there.
Start using the local display variable for all intel_de_* usage, and
opportunistically use it for other things than display registers as
well.

when driver requests uncleared memory we try to use uncleared but
fallback to cleared memory if necessary.

Otherwise, we prefer to keep the blocks as separated.

- For merging the 2 cleared blocks compare as below,
drm_buddy_is_clear(block) != drm_buddy_is_clear(buddy)(Christian)
- Defragment the memory beginning from min_order
till the required memory space is available.
v2: (Matthew)
- Add a wrapper drm_buddy_free_list_internal for the freeing of blocks
operation within drm buddy.
- Write a macro block_incompatible() to allocate the required blocks.
- Update the xe driver for the drm_buddy_free_list change in arguments.
- add a warning if the two blocks are incompatible on
defragmentation
- call full defragmentation in the fini() function
- place a condition to test if min_order is equal to 0
- replace the list with safe_reverse() variant as we might
remove the block from the list.
v3:
- fix Gitlab user reported lockup issue.
- Keep DRM_BUDDY_HEADER_CLEAR define sorted(Matthew)
- modify to pass the root order instead max_order in fini()
function(Matthew)
- change bool 1 to true(Matthew)
- add check if min_block_size is power of 2(Matthew)
- modify the min_block_size datatype to u64(Matthew)
v4:
- rename the function drm_buddy_defrag with __force_merge.
- Include __force_merge directly in drm buddy file and remove
the defrag use in amdgpu driver.
- Remove list_empty() check(Matthew)
- Remove unnecessary space, headers and placement of new variables(Matthew)
- Add a unit test case(Matthew)
v5:
- remove force merge support to actual range allocation and not to bail
out when contains && split(Matthew)
- add range support to force merge function.
v6:
- modify the alloc_range() function clear page non merged blocks
allocation(Matthew)
- correct the list_insert function name(Matthew).

Disable the px_clk when setting the rate to recover a fully
configured and correctly reset VCLK clock tree after the rate
is set.

The dmc_firmware_path parameter is clearly a display parameter. Move it
there so it's available to both i915 and xe modules. This also cleans up
the ugly member in struct xe_device.

The distinction between the dmc_firmware_path module param being NULL
and the empty string "" is problematic. It's not possible to set the
parameter back to NULL via sysfs or debugfs. Remove the distinction, and
consider NULL and the empty string to be the same thing, and use the
platform default for them.
This removes the possibility to disable DMC (and runtime PM) via
i915.dmc_firmware_path="". Instead, use "/dev/null" as the magic
firmware path to skip DMC firmware loading and disable runtime PM.
v2: Add support for i915.dmc_firmware_path="/dev/null" (Gustavo)

The big if ladder clutters intel_dmc_init(). Split it out to a separate
