d7d473d846 drm/panel: sharp-lq101r1sx01: Don't call disable at shutdown/remove
It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

A grep through mainline for compatible strings used by this driver
indicates that it is used by Tegra boards. The Tegra driver appears to
be correctly calling drm_atomic_helper_shutdown() so we can remove the
calls.

316bb1473c drm/panel: sharp-lq101r1sx01: Stop tracking prepared/enabled
As talked about in commit d2aacaf073 ("drm/panel: Check for already
prepared/enabled in drm_panel"), we want to remove needless code from
panel drivers that was storing and double-checking the
prepared/enabled state. Even if someone was relying on the
double-check before, that double-check is now in the core and not
needed in individual drivers.

A recent effort was made to fix as many DRM modeset drivers as

boards are now correctly calling drm_atomic_helper_shutdown() so we
can remove the calls.

2ccc698c68 drm/panel: boe-himax8279d: Don't call unprepare+disable at shutdown/remove
It's the responsibility of a correctly written DRM modeset driver to
call drm_atomic_helper_shutdown() at shutdown time and that should be
disabling / unpreparing the panel if needed. Panel drivers shouldn't
be calling these functions themselves.

A recent effort was made to fix as many DRM modeset drivers as
possible [1] [2] [3] and most drivers are fixed now.

Unfortunately, grepping mainline for this panel's compatible string
shows no hits, so we can't be 100% sure if the DRM modeset driver used
with this panel has been fixed. If it is found that the DRM modeset
driver hasn't been fixed then this patch could be temporarily reverted
until it is.

drm/bridge: samsung-dsim: Fix porch calcalcuation rounding
The VFP, HBP, and HSA are divided between the available lanes if
there is more than one lane.  For certain timings and lane
configurations, the HFP may not be evenly divisible. If the HFP
is rounded down, it ends up being too small which can cause some
monitors to not sync properly. In these instances, adjust htotal
and hsync to round the HFP up, and recalculate the htotal.

This allows 720P-60 to operation on an i.MX8MP with a four-lane
configuration.

drm/bridge: samsung-dsim: Set P divider based on min/max of fin pll
The P divider should be set based on the min and max values of
the fin pll which may vary between different platforms.
These ranges are defined per platform, but hard-coded values
were used instead which resulted in a smaller range available
on the i.MX8M[MNP] than what was possible.

As noted by Frieder, there are descripencies between the reference
manuals of the Mini, Nano and Plus, so I reached out to my NXP
rep and got the following response regarding the varing notes
in the documentation.

"Yes it is definitely wrong, the one that is part of the NOTE in
MIPI_DPHY_M_PLLPMS register table against PMS_P, PMS_M and PMS_S is
not correct. I will report this to Doc team, the one customer should
be take into account is the Table 13-40 DPHY PLL Parameters and the
Note above."

With this patch, the clock rates now match the values used in NXP's
downstream kernel.

drm/mediatek: Drop chain_mode_fixup call in mode_valid()
The mode_valid implementation had a call to
drm_bridge_chain_mode_fixup() which would be wrong as the mode_valid is
not allowed to change anything - only to validate the mode.

As the next bridge is often/always a connector the call had no effect
anyway. So drop it.

From the git history I could see this call was included in the original
version of the driver so there was no help there to find out why it was
added in the first place. But a lot has changed since the initial driver
were added and is seems safe to remove the call now.

drm/sun4i: Fix layer zpos change/atomic modesetting
Identical configurations of planes can lead to different (and wrong)
layer -> pipe routing at HW level, depending on the order of atomic
plane changes.

For example:

- Layer 1 is configured to zpos 0 and thus uses pipe 0. No other layer
  is enabled. This is a typical situation at boot.

- When a compositor takes over and layer 3 is enabled,
  sun8i_ui_layer_enable() will get called with old_zpos=0 zpos=1, which
  will lead to incorrect disabling of pipe 0 and enabling of pipe 1.

What happens is that sun8i_ui_layer_enable() function may disable
blender pipes even if it is no longer assigned to its layer.

To correct this, move the routing setup out of individual plane's
atomic_update into crtc's atomic_update, where it can be calculated
and updated all at once.

Remove the atomic_disable callback because it is no longer needed.

- b6x2g6x2r6x2, BGR666

BGR666 is presented to userspace as RGB888. The 2 LSB in each color
are discarded by the controller. The pixel is sent on the wire using
8 bits per word (little endian) so the controller sees it as BGR.

RGB565 is the default if the property is not present.

4aebb79021 drm/mipi-dbi: Add support for DRM_FORMAT_RGB888
DRM_FORMAT_RGB888 is 24 bits per pixel and it would be natural to send it
on the SPI bus using a 24 bits per word transfer. The problem with this
is that not all SPI controllers support 24 bpw.

Since DRM_FORMAT_RGB888 is stored in memory as little endian and the SPI
bus is big endian we use 8 bpw to always get the same pixel format on the
bus: b8g8r8.

The MIPI DCS specification lists the standard commands that can be sent
over the MIPI DBI interface. The set_address_mode (36h) command has one
bit in the parameter that controls RGB/BGR order. This means that the
controller can be configured to receive the pixel as BGR.

RGB888 is rarely supported on these controllers but RGB666 is very common.
All datasheets I have seen do at least support the pixel format option
where each color is sent as one byte and the 6 MSB's are used.

All this put together means that we can send each pixel as b8g8r8 and an
RGB666 capable controller sees this as b6x2g6x2r6x2.

df3fb27a74 drm/mipi-dbi: Make bits per word configurable for pixel transfers
MIPI DCS write/set commands have 8 bit parameters except for the
write_memory commands where it depends on the pixel format.
drm_mipi_dbi does currently only support RGB565 which is 16-bit and it
has to make sure that the pixels enters the SPI bus in big endian format
since the MIPI DBI spec doesn't have support for little endian.

drm_mipi_dbi is optimized for DBI interface option 3 which means that the
16-bit bytes are swapped by the upper layer if the SPI bus does not
support 16 bits per word, signified by the swap_bytes member.

In order to support both 16-bit and 24-bit pixel transfers we need a way
to tell the DBI command layer the format of the buffer. Add a
write_memory_bpw member that the upper layer can use to tell how many
bits per word to use for the SPI transfer.

f34f014c84 drm/mipi-dbi: Remove mipi_dbi_machine_little_endian()
mipi_dbi_machine_little_endian() should really have been called
mipi_dbi_framebuffer_little_endian() because that's the function it
performs. When I added support for these SPI displays I thought that the
framebuffers on big endian machines were also big endian, but I have
later learned that this is not the case. There's a bit in the fourcc code
that controls this: DRM_FORMAT_BIG_ENDIAN.

Just remove the function to avoid confusion. We can add big endian support
later should the need arise and we have hardware to test on.

Instead of just amending the docs, expand it to explain the endianness
handling.

fdb164667b dt-bindings: display: panel: mipi-dbi-spi: Add a pixel format property
The MIPI DBI 2.0 specification (2005) lists only two pixel formats for
the Type C Interface (SPI) and that is 3-bits/pixel RGB111 with
2 options for bit layout.

For Type A and B (parallel) the following formats are listed: RGB332,
RGB444, RGB565, RGB666 and RGB888 (some have 2 options for the bit layout).

Many MIPI DBI compatible controllers support all interface types on the
same chip and often the manufacturers have chosen to provide support for
the Type A/B interface pixel formats also on the Type C interface.

Some chips provide many pixel formats with optional bit layouts over SPI,
but the most common by far are RGB565 and RGB666. So even if the
specification doesn't list these formats for the Type C interface, the
industry has chosen to include them.

The MIPI DCS specification lists the standard commands that can be sent
over the MIPI DBI interface. The set_address_mode (36h) command has one
bit in the parameter that controls RGB/BGR order:
    This bit controls the RGB data latching order transferred from the
    peripheral’s frame memory to the display device.
This means that each supported RGB format also has a BGR variant.

Based on this rationale document the following pixel formats describing
the bit layout going over the wire:
- RGB111 (option 1): x2r1g1b1r1g1b1 (2 pixels per byte)
- BGR111 (option 1): x2b1g1r1b1g1r1 (2 pixels per byte)
- RGB111 (option 2): x1r1g1b1x1r1g1b1 (2 pixels per byte)
- BGR111 (option 2): x1b1g1r1x1b1g1r1 (2 pixels per byte)
- RGB565: r5g6b5 (2 bytes)
- BGR565: b5g6r5 (2 bytes)
- RGB666: r6x2g6x2b6x2 (3 bytes)
- BGR666: b6x2g6x2r6x2 (3 bytes)
(x: don't care)

v2:
- Use 'default: r5g6b5' (Rob)

  [ ] 0000:00:00.0: [drm] foo bar
  [ ] 0000:00:00.0: [drm] *ERROR* foo

Add a generic __drm_dev_vprintk() function that can format the
final message like all other existing function do and allows us
to keep the formatting code in one place.
