Heiko Stuebner d1479d028a drm/panel: add panel driver for Xinpeng XPP055C272 panels
Base on the somewhat similar Rocktech driver but adapted for
panel-specific init of the XPP055C272.

changes in v5:
- drop error message when backlight not found, no other panel
  does that and if needed it should live in drm_panel_of_backlight
changes in v4:
  none
changes in v3:
- remove wrong negative sync flags from display-mode to fix a display
  artifact of the output getting move a tiny bit to the right
changes in v2:
- move to drm-panel-internal backlight handling (Sam)
- adapt to changes that happened to drm_panel structs+functions (Sam)
- sort includes (Sam)
- drop unnecessary DRV_NAME constant (Sam)
- do mipi_dsi_dcs_exit_sleep_mode and mipi_dsi_dcs_set_display_on
  in panel prepare (not init_sequence) to keep symmetric (Sam)

Christophe JAILLET 3c911fe799 pxa168fb: Fix the function used to release some memory in an error handling path
In the probe function, some resources are allocated using 'dma_alloc_wc()',
they should be released with 'dma_free_wc()', not 'dma_free_coherent()'.

We already use 'dma_free_wc()' in the remove function, but not in the
error handling path of the probe function.

Also, remove a useless 'PAGE_ALIGN()'. 'info->fix.smem_len' is already
PAGE_ALIGNed.

Geert Uytterhoeven 2ce18249af drm/mipi_dbi: Fix off-by-one bugs in mipi_dbi_blank()
When configuring the frame memory window, the last column and row
numbers are written to the column resp. page address registers.  These
numbers are thus one less than the actual window width resp. height.

While this is handled correctly in mipi_dbi_fb_dirty() since commit
03ceb1c8df ("drm/tinydrm: Fix setting of the column/page end
addresses."), it is not in mipi_dbi_blank().  The latter still forgets
to subtract one when calculating the most significant bytes of the
column and row numbers, thus programming wrong values when the display
width or height is a multiple of 256.

drm/sun4i: dsi: Handle bus clock via regmap_mmio_attach_clk
regmap has special API to enable the controller bus clock while
initializing register space, and current driver is using
devm_regmap_init_mmio_clk which require to specify bus
clk_id argument as "bus"

But, the usage of clocks are varies between different Allwinner
DSI controllers. Clocking in A33 would need bus and mod clocks
where as A64 would need only bus clock.

Since A64 support only single bus clock, it is optional to
specify the clock-names on the controller device tree node.
So using NULL on clk_id would get the attached clock.

To support clk_id as "bus" and "NULL" during clock enablement
between controllers, this patch add generic code to handle
the bus clock using regmap_mmio_attach_clk with associated
regmap APIs.

dt-bindings: sun6i-dsi: Document A64 MIPI-DSI controller
The MIPI DSI controller in Allwinner A64 is similar to A33.

But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to have separate compatible for A64 on the same driver.

DSI_SCLK uses mod clock-names on dt-bindings, so the same
is not required for A64.

On that note
- A64 require minimum of 1 clock like the bus clock
- A33 require minimum of 2 clocks like both bus, mod clocks

So, update dt-bindings so-that it can document both A33,
A64 bindings requirements.

Dhinakaran Pandiyan b3e57bccd6 drm/i915/tgl: Gen-12 render decompression
Gen-12 display decompression operates on Y-tiled compressed main surface.
The CCS is linear and has 4 bits of metadata for each main surface cache
line pair, a size ratio of 1:256. Gen-12 display decompression is
incompatible with buffers compressed by earlier GPUs, so make use of a new
modifier to identify gen-12 compression. Another notable change is that
render decompression is supported on all planes except cursor and on all
pipes. Start by adding render decompression support for [A,X]BGR888 pixel
formats.

v2: Fix checkpatch warnings (Lucas)
v3:
Rebase, disable color clear, styling changes and modify
intel_tile_width_bytes and intel_tile_height to handle linear CCS
v4:
- Use format block descriptors and the i915 specific func to get the
  subsampling for each color plane.
- Use helpers to convert between CCS and main planes.
v5:
- Fix subsampling returned by intel_fb_plane_get_subsampling() for
  the CCS plane of the first plane.
v6:
- Rebased on v2 of patch 4.
v7:
- Fix plane dimensions during FB check.
