As the removed comments say, these aren't DT based devices.
of_dma_configure() is going to stop allowing a NULL DT node and calling
it will no longer work.
The comment is also now out of date as of commit 9ab91e7c5c51 ("arm64:
default to the direct mapping in get_arch_dma_ops"). Direct mapping
is now the default rather than dma_dummy_ops.
According to Stefano and Oleksandr, the only other part needed is
setting the DMA masks and there's no reason to restrict the masks to
32-bits. So set the masks to 64 bits.

We have a src and dect rectangle, use it instead of relying on
the core drm properties.
Because the core by default clips the src/dst properties, after
the drm_atomic_helper_check_plane_state() we manually set the
unclipped src/dst rectangles. We still need the call for
visibility checks, but this way we are able to use the src/dst
rects in the check/commit code.
This removes the special case in the watermark code for cursor w/h.

This can all be done from the intel_update_crtc function. Split out the

Pull in all the changes done during fastset as well. It makes no sense

[cherry-picked to drm-misc-fixes: drm-misc-next commit dfef959803c7]
Commit 554b3529fe01 ("thermal/drivers/core: Remove the module Kconfig's
option") changed the type of THERMAL from tristate to bool, so
THERMAL || !THERMAL is now always y. Remove the redundant dependency.
Discovered through Kconfiglib detecting a dependency loop. The C tools
simplify the expression to y before running dependency loop detection,
and so don't see it. Changing the type of THERMAL back to tristate makes
the C tools detect the same loop.
Not sure if running dep. loop detection after simplification can be
called a bug. Fixing this nit unbreaks Kconfiglib on the kernel at
least.

the hdr_output_metadata connector property.
This patch adds a use_drm_infoframe flag to dw_hdmi_plat_data that platform
drivers use to signal when Dynamic Range and Mastering infoframes is supported.
This flag is needed because Amlogic GXBB and GXL report same DW-HDMI version,
and only GXL support DRM InfoFrame.

the datasheets aren't available for these devices, and we only have the
downstream kernel sources to look at, let's assume that these addresses
are fixed based on the model, and pass the i2c addresses to the driver
via the data pointer in the driver's of_match_table.

max_tu_symbol was programmed to TU_SIZE_RECOMMENDED - 1, which is not
what the spec says. The spec says:
roundup ((input active video bandwidth in bytes/output active video
bandwidth in bytes) * tu_size)
It is not quite clear what the above means, but calculating
max_tu_symbol = (input Bps / output Bps) * tu_size seems to work and
fixes the issues seen.
This fixes artifacts in some videomodes (e.g. 1024x768@60 on 2-lanes &

There are small differences between the blitter and the video engines in
the xcs context image (e.g. registers 0x200 and 0x204 only exist on the
blitter). Since we never explicitly set a value for those register and
given that we don't need to update the offsets in the lrc image when we
change engine within the class for virtual engine because the HW can
handle that, instead of having a separate define for the BCS we can
just restrict the programming to the part we're interested in, which is
common across the engines.

commit d6abe6df706c ("drm/bridge: sil_sii8620: do not have a dependency
of RC_CORE") changed the driver to select both RC_CORE and INPUT.
However, this causes problems with other drivers, in particular an input
driver that depends on MFD_INTEL_LPSS_PCI (to be added in a separate
commit):
drivers/clk/Kconfig:9:error: recursive dependency detected!
drivers/clk/Kconfig:9: symbol COMMON_CLK is selected by MFD_INTEL_LPSS
drivers/mfd/Kconfig:566: symbol MFD_INTEL_LPSS is selected by MFD_INTEL_LPSS_PCI
drivers/mfd/Kconfig:580: symbol MFD_INTEL_LPSS_PCI is implied by KEYBOARD_APPLESPI
drivers/input/keyboard/Kconfig:73: symbol KEYBOARD_APPLESPI depends on INPUT
drivers/input/Kconfig:8: symbol INPUT is selected by DRM_SIL_SII8620
drivers/gpu/drm/bridge/Kconfig:83: symbol DRM_SIL_SII8620 depends on DRM_BRIDGE
drivers/gpu/drm/bridge/Kconfig:1: symbol DRM_BRIDGE is selected by DRM_PL111
drivers/gpu/drm/pl111/Kconfig:1: symbol DRM_PL111 depends on COMMON_CLK
According to the docs and general consensus, select should only be used
for non user-visible symbols, but both RC_CORE and INPUT are
user-visible. Furthermore almost all other references to INPUT
throughout the kernel config are depends, not selects. For this reason
the first part of this change reverts the commit.
In order to address the original reason for the commit, namely
that not all boards use the remote controller functionality and hence
should not need have to deal with RC_CORE, the second part of this
change now makes the remote control support in the driver optional and
contingent on RC_CORE being defined. And with this the hard dependency
on INPUT also goes away as that is only needed if RC_CORE is defined
(which in turn already depends on INPUT).

Due to the nature of preempt-to-busy the execlists active tracking and
the schedule queue may become temporarily desync'ed (between resubmission
to HW and its ack from HW). This means that we may have unwound a
request and passed it back to the virtual engine, but it is still
inflight on the HW and may even result in a GPU hang. If we detect that
GPU hang and try to reset, the hanging request->engine will no longer
match the current engine, which means that the request is not on the
execlists active list and we should not try to find an older incomplete
request. Given that we have deduced this must be a request on a virtual
engine, it is the single active request in the context and so must be
guilty (as the context is still inflight, it is prevented from being
executed on another engine as we process the reset).

If we are asked to submit a completed request, just move it onto the
active-list without modifying it's payload. If we try to emit the
modified payload of a completed request, we risk racing with the
ring->head update during retirement which may advance the head past our
breadcrumb and so we generate a warning for the emission being behind
the RING_HEAD.

The CMP PCH ID we have in the driver is correct for the CML-U machines we have
in our CI system, but the CML-S and CML-H CI machines appear to use a
different PCH ID, leading our driver to detect no PCH for them.

I'm embarassed to say that even though I've touched
vop_crtc_mode_fixup() twice and I swear I tested it, there's still a
stupid glaring bug in it. Specifically, on veyron_minnie (with all
the latest display timings) we want to be setting our pixel clock to
66,666,666.67 Hz and we tell userspace that's what we set, but we're
actually choosing 66,000,000 Hz. This is confirmed by looking at the
clock tree.
The problem is that in drm_display_mode_from_videomode() we convert
from Hz to kHz with:
dmode->clock = vm->pixelclock / 1000;
...and drm_display_mode_from_videomode() is called from panel-simple
when we have an "override_mode" like we do on veyron_minnie. See
commit 123643e5c40a ("ARM: dts: rockchip: Specify
rk3288-veyron-minnie's display timings").
...so when the device tree specifies a clock of 66666667 for the panel
then DRM translates that to 66666000. The clock framework will always
pick a clock that is _lower_ than the one requested, so it will refuse
to pick 66666667 and we'll end up at 66000000.
While we could try to fix drm_display_mode_from_videomode() to round
to the nearest kHz and it would fix our problem, it wouldn't help if
the clock we actually needed was 60,000,001 Hz. We could
alternatively have DRM always round up, but maybe this would break
someone else who already baked in the assumption that DRM rounds down.
Specifically note that clock drivers are not consistent about whether
they round up or round down when you call clk_set_rate(). We know how
Rockchip's clock driver works, but (for instance) you can see that on
most Qualcomm clocks the default is clk_rcg2_ops which rounds up.
Let's solve this by just adding 999 Hz before calling
clk_round_rate(). This should be safe and work everywhere. As
discussed in more detail in comments in the commit, Rockchip's PLLs
are configured in a way that there shouldn't be another PLL setting
that is only a few kHz off so we won't get mixed up.
NOTE: if this is picked to stable, it's probably easiest to first pick
commit 527e4ca3b6d1 ("drm/rockchip: Base adjustments of the mode based
on prev adjustments") which shouldn't hurt in stable.

Now that we dropped the engine->active.lock serialisation from around
process_csb(), direct submission can run concurrently to the interrupt
handler. As such execlists->active may be advanced as we dequeue,
dropping the reference to the request. We need to employ our RCU request
protection to ensure that the request is not freed too early.

Panfrost uses multiple schedulers (one for each slot, so 2 in reality),
and on a timeout has to stop all the schedulers to safely perform a
reset. However more than one scheduler can trigger a timeout at the same
time. This race condition results in jobs being freed while they are
still in use.
When stopping other slots use cancel_delayed_work_sync() to ensure that
any timeout started for that slot has completed. Also use
mutex_trylock() to obtain reset_lock. This means that only one thread
attempts the reset, the other threads will simply complete without doing
anything (the first thread will wait for this in the call to
cancel_delayed_work_sync()).
While we're here and since the function is already dependent on
sched_job not being NULL, let's remove the unnecessary checks.

Currently the property docs don't specify whether it's okay for two planes to
have the same zpos value and what user-space should expect in this case.
The unspoken, legacy rule used in the past was to make user-space figure
out the zpos from object IDs. However some drivers break this rule,
that's why the ordering is documented as unspecified in case the zpos
property is missing. User-space should rely on the zpos property only.
There are some cases in which user-space might read identical zpos
values for different planes.
For instance, in case the property is mutable, user-space might set two
planes' zpos to the same value. This is necessary to support user-space
using the legacy DRM API where atomic commits are not possible:
user-space needs to update the planes' zpos one by one.
Because of this, user-space should handle multiple planes with the same
zpos.
While at it, remove the assumption that zpos is only for overlay planes.
Additionally, update the drm_plane_state.zpos docs to clarify that zpos
disambiguation via plane object IDs is a recommendation for drivers, not
something user-space can rely on. In other words, when user-space sets
the same zpos on two planes, drivers should rely on the plane object ID.
v2: clarify drm_plane_state.zpos docs (Daniel)
v3: zpos is for all planes (Marius, Daniel)
v4: completely reword the drm_plane_state.zpos docs to make it clear the
recommendation to use plane IDs is for drivers in case user-space uses
duplicate zpos values (Pekka)
v5: reword commit message (Pekka, James)
v6: remove mention of Arm GPUs having planes which can't overlap,
because this isn't uAPI yet (Daniel)

Polaris and vegam use count for the value rather than
level. This looks like a copy paste typo from when
the code was adapted from previous asics.
I'm not sure that the SMU actually uses this value, so
