bbeba09fc8 drm/docs: Document "scaling mode" property better
Move it out of the csv dungeon.

While at it add the missing link to the helper functions for setting
up the "panel rotation" property.

Also OCD how we list enum property values and their corresponding docs.
Going for a nest definition list seams cleanest, no need for also making
it an uordered list.

4d10bd45d4 drm/docs: Align layout of optional plane blending properties
Just a bit of drive-by OCD. All the other property docs use enumerations,
for some nice visual consistency. It also neatly highlights the property
name.

40275dc4ed drm: simple_kms_helper: Add mode_valid() callback support
The PL111 needs to filter valid modes based on memory bandwidth.
I guess it is a pretty simple operation, so we can still claim
the DRM KMS helper pipeline is simple after adding this (optional)
vtable callback.

e86584c537 drm: Use idr_init_base(1) when using id==0 for invalid
Use the new idr_init_base() function to create an IDR that knows id==0
is never allocated as it maps to an invalid identifier. By knowing that
id==0 is invalid, the IDR can start from id=1 instead avoiding the issue
of having to start each lookup from the zeroth leaf as id==0 is always
unused (and thus the tree-of-bitmaps indicate that is the first
available).

a5ef656736 drm: NULL pointer dereference [null-pointer-deref] (CWE 476) problem
The Parfait (version 2.1.0) static code analysis tool found the
following NULL pointer derefernce problem.

- drivers/gpu/drm/drm_edid.c
The call to drm_cvt_mode() in function drm_mode_std() for the
HDTV hack resulted in the possibility of accessing a NULL pointer
if drm_mode_std() returned NULL.  A check for this added right after
the call to drm_cvt_mode() in this particular area of code.

57de50af16 drm/rockchip: Respect page offset for PRIME mmap calls
When mapping external DMA-bufs through the PRIME mmap call, we might be
given an offset which has to be respected. However for the internal DRM
GEM mmap path, we have to ignore the fake mmap offset used to identify
the buffer only. Currently the code always zeroes out vma->vm_pgoff,
which breaks the former.

This patch fixes the problem by moving the vm_pgoff assignment to a
function that is used only for GEM mmap path, so that the PRIME path
retains the original offset.

drm/bridge/synopsys: dw-hdmi: don't clobber drvdata
dw_hdmi shouldn't set drvdata since some drivers might need to store
it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi
instead to store it in drvdata. This way drivers are responsible to
store and pass structure when needed.

Idea was taken from the following commit:

drm/bridge/synopsys: dw-hdmi: Export some PHY related functions
Parts of PHY code could be useful also for custom PHYs. For example,
Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY
with few additional memory mapped registers, so most of the Synopsys PHY
related code could be reused.

Functions exported here are actually not specific to Synopsys PHYs but
to DWC HDMI controller PHY interface. This means that even if the PHY is
completely custom, i.e. not designed by Synopsys, exported functions can
be useful.

a9a08845e9 vfs: do bulk POLL* -> EPOLL* replacement
This is the mindless scripted replacement of kernel use of POLL*
variables as described by Al, done by this script:

    for V in IN OUT PRI ERR RDNORM RDBAND WRNORM WRBAND HUP RDHUP NVAL MSG; do
        L=`git grep -l -w POLL$V | grep -v '^t' | grep -v /um/ | grep -v '^sa' | grep -v '/poll.h$'|grep -v '^D'`
        for f in $L; do sed -i "-es/^\([^\"]*\)\(\<POLL$V\>\)/\\1E\\2/" $f; done
    done

with de-mangling cleanups yet to come.

NOTE! On almost all architectures, the EPOLL* constants have the same
values as the POLL* constants do.  But they keyword here is "almost".
For various bad reasons they aren't the same, and epoll() doesn't
actually work quite correctly in some cases due to this on Sparc et al.

The next patch from Al will sort out the final differences, and we
should be all done.

65101d8c91 drm/vc4: Expose performance counters to userspace
The V3D engine has various hardware counters which might be interesting
to userspace performance analysis tools.

Expose new ioctls to create/destroy a performance monitor object and
query the counter values of this perfmance monitor.

Note that a perfomance monitor is given an ID that is only valid on the
file descriptor it has been allocated from. A performance monitor can be
attached to a CL submission and the driver will enable HW counters for
this request and update the performance monitor values at the end of the
job.

3b6ec45857 drm/pl111: Support multiple endpoints on the CLCD
The Versatile PL110 implementations use multiple endpoints:
from the PL111 port, the lines are routed through a PLD,
and from there forked so the same lines go to a VGA DAC and
an external TFT panel connector. This is discrete wireing
so there is no way to turn of one output, i.e. this is
really two endpoints, not two ports.

We model this with multiple endpoints, so we need to loop
over the available endpoints, check for panel or bridge on
each and accumulate the result before continuing.

The code already will give the panel preference over the
bridge, if present, so the output will be sent to the panel
if both a panel and a bridge is present on two endpoints
of the same port.

If they all return -EPROBE_DEFER we return -EPROBE_DEFER
as well.

If just one endpoint is present on the port, the behaviour
is the same as before.

08e3211251 drm/pl111: Support variants with broken VBLANK
The early Integrator CLCD synthesized in the Integrator CP and
IM-PD1 FPGAs are broken: their vertical and next base interrupts
are not functional. Support these variants by simply disabling
the use of the vblank interrupt on these variants.

6470b7ddec drm/pl111: Handle the Versatile RGB/BGR565 mode
The ARM Versatile series can do RGB/BGR565 with an external
"PLD" (Programmable Logical Device). However the CLCD does not
have control bits for this, so it needs to be set into the
ordinary 16BPP mode, then the RGB/BGR565 handling of the pixel
data is handled by configuring the PLD through the external
register.

3d95f76a11 drm/pl111: Properly detect the ARM PL110 variants
With a bit of refactoring we can contain the variant data for
the strange PL110 versions that is feature-incomplete PL110 for
the ARM Integrator/CP and somewhere inbetween PL110 and PL111
for the ARM Versatile AB and Versatile PB.

We also accomodate for the custom duct-taped RGB565/BGR565 support
in the Versatile variant.

f40f5b87d9 drm/panel: Add support for ARM Versatile panels
The ARM reference designs "Versatile AB" and "Versatile PB"
contain panel connectors with autodetection of the connected
panel type. This adds a small driver utilizing the MFD syscon
look-up to read the autodetection register and set up the
corresponding panel appropriately.

In the source file there is a bit of elaboration of the
panel types and interfaces on these boards.

This was tested with the PL111 DRM driver on the ARM Versatile
AB with the IB2 daughterboard.

6e3322c226 drm/i915/cnp: Properly handle VBT ddc pin out of bounds.
If the table result is out of bounds on the array map
there is something really wrong with VBT pin so we don't
return that vbt_pin, but only return 0 instead.

This basically reverts commit 'a8e6f3888b05 ("drm/i915/cnp:
Ignore VBT request for know invalid DDC pin.")'

Also this properly fixes commit 9c3b2689d0 ("drm/i915/cnl:
Map VBT DDC Pin to BSpec DDC Pin.")

v2: Do in a way that we don't break other platforms. (Jani)

v3: Keep debug message (Jani)

v4: Don't mess with 0 mapping was noticed by Jani and
    addressed with a simple solution suggested by Lucas
    that makes this even simpler.

b3ad99ed45 drm/i915/cmdparser: Do not check past the cmd length.
The command MEDIA_VFE_STATE checks bits at offset +2 dwords. However, it is
possible to have MEDIA_VFE_STATE command with length = 0 + LENGTH_BIAS = 2.
In that case check_cmd will read bits from the following command, or even past
the end of the buffer.

If the offset ends up outside of the command length, reject the command.
