f0f427f385 drm/edid: fix parsing of 3D modes from HDMI VSDB
commit 72794d16bd535a984e6653a18f5862405b49b5f9 upstream.

Commit 537d9ed2f6c1 ("drm/edid: convert add_cea_modes() to use cea db
iter") inadvertently moved the do_hdmi_vsdb_modes() call within the db
iteration loop, always passing NULL as the CTA VDB to
do_hdmi_vsdb_modes(), skipping a lot of stereo modes.

Move the call back outside of the loop.

This does mean only one CTA VDB and HDMI VSDB combination will be
handled, but it's an unlikely scenario to have more than one of either
block, and it was not accounted for before the regression either.

26cbe4c63d drm/edid: fix AVI infoframe aspect ratio handling
commit 1cbc1f0d324ba6c4d1b10ac6362b5e0b029f63d5 upstream.

We try to avoid sending VICs defined in the later specs in AVI
infoframes to sinks that conform to the earlier specs, to not upset
them, and use 0 for the VIC instead. However, we do this detection and
conversion to 0 too early, as we'll need the actual VIC to figure out
the aspect ratio.

In particular, for a mode with 64:27 aspect ratio, 0 for VIC fails the
AVI infoframe generation altogether with -EINVAL.

Separate the VIC lookup from the "filtering", and postpone the
filtering, to use the proper VIC for aspect ratio handling, and the 0
VIC for the infoframe video code as needed.

The source of this warning is in iosys_map_clear() called from
dma_buf_vmap(). It conditionally sets values based on map->is_iomem. The
iosys_map variables are allocated uninitialized on the stack leading to
->is_iomem having all kinds of values and not only 0/1.

Fix this by zeroing the iosys_map variables.

be11d0d9c4 drm/i915: Don't use BAR mappings for ring buffers with LLC
commit 85636167e3206c3fbd52254fc432991cc4e90194 upstream.

Direction from hardware is that ring buffers should never be mapped
via the BAR on systems with LLC. There are too many caching pitfalls
due to the way BAR accesses are routed. So it is safest to just not

8551ddbff0 drm/radeon: Fix eDP for single-display iMac11,2
commit 05eacc198c68cbb35a7281ce4011f8899ee1cfb8 upstream.

Apple iMac11,2 (mid 2010) also with Radeon HD-4670 that has the same
issue as iMac10,1 (late 2009) where the internal eDP panel stays dark on
driver load.  This patch treats iMac11,2 the same as iMac10,1,
so the eDP panel stays active.

Additional steps:
Kernel boot parameter radeon.nomodeset=0 required to keep the eDP
panel active.

This patch is an extension of
commit 564d8a2cf3ab ("drm/radeon: Fix eDP for single-display iMac10,1 (v2)")

[ Upstream commit 39934d3ed5725c5e3570ed1b67f612f1ea60ce03 ]

This reverts commit fac53471d0ea9693d314aa2df08d62b2e7e3a0f8.
The following change: move the drm_dev_unplug call after
amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is
the following: amdgpu_pci_remove calls drm_dev_unregister
and it should be called first to ensure userspace can't access the
device instance anymore. If we call drm_dev_unplug after
amdgpu_driver_unload_kms then we observe IGT PCI software unplug
test failure (kernel hung) for all ASICs. This is how this
regression was found.

After this revert, the following commands do work not, but it would
be fixed in the next commit:
 - sudo modprobe -r amdgpu
 - sudo modprobe amdgpu

d50cd50f61 drm: rcar-du: Fix setting a reserved bit in DPLLCR
[ Upstream commit 5fbc2f3b91d27e12b614947048764099570cbb55 ]

On H3 ES1.x two bits in DPLLCR are used to select the DU input dot clock
source. These are bits 20 and 21 for DU2, and bits 22 and 23 for DU1. On
non-ES1.x, only the higher bits are used (bits 21 and 23), and the lower
bits are reserved and should be set to 0.

The current code always sets the lower bits, even on non-ES1.x.

For both DU1 and DU2, on all SoC versions, when writing zeroes to those
bits the input clock is DCLKIN, and thus there's no difference between
ES1.x and non-ES1.x.

For DU1, writing 0b10 to the bits (or only writing the higher bit)
results in using PLL0 as the input clock, so in this case there's also
no difference between ES1.x and non-ES1.x.

However, for DU2, writing 0b10 to the bits results in using PLL0 as the
input clock on ES1.x, whereas on non-ES1.x it results in using PLL1. On
ES1.x you need to write 0b11 to select PLL1.

The current code always writes 0b11 to PLCS0 field to select PLL1 on all
SoC versions, which works but causes an illegal (in the sense of not
allowed by the documentation) write to a reserved bit field.

To remove the illegal bit write on PLSC0 we need to handle the input dot
clock selection differently for ES1.x and non-ES1.x.

Add a new quirk, RCAR_DU_QUIRK_H3_ES1_PLL, for this. This way we can
always set the bit 21 on PLSC0 when choosing the PLL as the source
clock, and additionally set the bit 20 when on ES1.x.

if so, apply a workaround.

We will need another H3 ES1.x check in the following patch, so rather than
adding more soc_device_match() calls, let's add a rcar_du_device_info
entry for the ES1, and a quirk flag,
RCAR_DU_QUIRK_H3_ES1_PCLK_STABILITY, for the workaround.

On DCN314 when resuming from s0i3 an ASSERT is shown indicating that
`VBIOSSMC_MSG_SetHardMinDcfclkByFreq` returned `VBIOSSMC_Result_Failed`.

This isn't a driver bug; it's a BIOS/configuration bug. To make this

This matches the behavior utilized for failures with

[Why]

of an active DP stream.

[How]
Wait until DP vid stream is disabled before turning off the FIFO.

The FIFO reset on DP unblank should take care of clearing any FIFO

dbe9140ed6 drm/tiny: ili9486: Do not assume 8-bit only SPI controllers
[ Upstream commit 77772e607522daa61f3af74df018559db75c43d6 ]

The pixel data for the ILI9486 is always 16-bits wide and it must be
sent over the SPI bus. When the controller is only able to deal with
8-bit transfers, this 16-bits data needs to be swapped before the
sending to account for the big endian bus, this is on the contrary not
needed when the SPI controller already supports 16-bits transfers.

The decision about swapping the pixel data or not is taken in the MIPI
DBI code by probing the controller capabilities: if the controller only
suppors 8-bit transfers the data is swapped, otherwise it is not.

This swapping/non-swapping is relying on the assumption that when the
controller does support 16-bit transactions then the data is sent
unswapped in 16-bits-per-word over SPI.

The problem with the ILI9486 driver is that it is forcing 8-bit
transactions also for controllers supporting 16-bits, violating the
assumption and corrupting the pixel data.

Align the driver to what is done in the MIPI DBI code by adjusting the
transfer size to the maximum allowed by the SPI controller.

[ Upstream commit 91aeaed2c1147e3b1157dc084d23f190856a6c23 ]

According to Figure 16 Turnaround Procedure on page 36 in [1], you
can see the status of LP-00 -> LP10 -> LP11. This state can correspond
to the state of DSI from LP00 -> LP11 in mtk_dsi_lane_ready function
in mtk_dsi.c.

LP-00 -> LP10 -> LP11 takes about 2*TLPX time (refer to [1] page 51
to see that TLPX is 50ns)

The delay at the end of the mtk_dsi_lane_ready function should be
greater than the 2*TLPX specified by the DSI spec, and less than
the time specified by the DSI_RX (generally 6ms to 40ms), to avoid
problems caused by the RX specification

dd5e3d8300 drm/msm/dpu: set pdpu->is_rt_pipe early in dpu_plane_sspp_atomic_update()
[ Upstream commit 1d233b1cb149ec78c20fac58331b27bb460f9558 ]

The function dpu_plane_sspp_atomic_update() updates pdpu->is_rt_pipe
flag, but after the commit 854f6f1c653b ("drm/msm/dpu: update the qos
remap only if the client type changes") it sets the flag late, after all
the qos functions have updated QoS programming. Move the flag update
back to the place where it happened before the mentioned commit to let
the pipe be programmed according to its current RT/non-RT state.

7009b78bb9 gpu: host1x: Don't skip assigning syncpoints to channels
[ Upstream commit eb258cc1fd458e584082be987dbc6ec42668c05e ]

The code to write the syncpoint channel assignment register
incorrectly skips the write if hypervisor registers are not available.

The register, however, is within the guest aperture so remove the
check and assign syncpoints properly even on virtualized systems.

strscpy instead. This fixes following warning:
