drm: Add FEC registers for LT-tunable repeaters
FEC is supported since DP 1.4, and it was expanded for LT-tunable in DP
1.4a. This commit adds the address registers for
FEC_ERROR_COUNT_PHY_REPEATER1 and FEC_CAPABILITY_PHY_REPEATER1.

Fix typo in word 'blend' and in the word 'destination' and change
preposition 'at' to 'of' in function 'blend' documentation.
And change the task introduction word 'Todo' for the word all in uppercase
- 'TODO'. With the TODO word all in uppercase (as it's the standard) it's
easier to find the tasks that have to be done throughout the code.

drm/dp_mst: Clear all payload id tables downstream when initializing
It seems that on certain MST hubs, namely the CableMatters USB-C 2x DP
hub, using the DP_PAYLOAD_ALLOCATE_SET and DP_PAYLOAD_TABLE_UPDATE_STATUS
register ranges to clear any pre-existing payload allocations on the hub isn't
always enough to reset things if the source device has been reset unexpectedly.
Or at least, that's the current running theory. The precise behavior appears to
be that when the source device gets reset unexpectedly, the hub begins reporting
an available_pbn value of 0 for all of its ports. This is a bit inconsistent
with the our theory, since this seems to happen even if previously set PBN
allocations should have resulted in a non-zero available_pbn value. So, it's
possible that something else may be going on here.
Strangely though, sending a CLEAR_PAYLOAD_ID_TABLE broadcast request when
initializing the MST topology seems to bring things into working order and make
available_pbn work again. Since this is a pretty safe solution, let's go ahead
and implement it.
Changes since v1:
* Change indenting on drm_dp_send_clear_payload_id_table() prototype
* Remove some braces in drm_dp_send_clear_payload_id_table()
* Reorganize some variable declarations in drm_dp_send_clear_payload_id_table()
* Don't forget to handle DP_CLEAR_PAYLOAD_ID_TABLE in
drm_dp_sideband_parse_reply()
* Move drm_dp_send_clear_payload_id_table() call into
drm_dp_mst_link_probe_work(), since we can't send sideband messages
while under lock in drm_dp_mst_topology_mgr_set_mst()
* Change commit message

video: constify fb ops across all drivers
Now that the fbops member of struct fb_info is const, we can start
making the ops const as well.
This does not cover all drivers; some actually modify the fbops struct,
for example to adjust for different configurations, and others do more
involved things that I'd rather not touch in practically obsolete
drivers. Mostly this is the low hanging fruit where we can add "const"
and be done with it.
v3:
- un-constify atyfb, mb862xx, nvidia and uvesabf (0day)
v2:
- fix typo (Christophe de Dinechin)
- use "static const" instead of "const static" in mx3fb.c

video: fb_defio: preserve user fb_ops
Modifying fb_ops directly to override fb_mmap with fb_deferred_io_mmap
and then resetting it to NULL afterwards causes problems all over the
place. First, it prevents making the fbops member of struct fb_info a
const pointer, which means we can't make struct fb_ops const
anywhere. Second, a few places have to go out of their way to restore
the original fb_mmap pointer that gets reset to NULL.
Since the only user of the fbops->fb_mmap hook is fb_mmap() in fbmem.c,
call fb_deferred_io_mmap() directly when deferred IO is enabled, and
avoid modifying fb_ops altogether.
Simply use info->fbdefio to determine whether deferred IO should be used
or not. This should be accurate enough for all use cases, although
perhaps not pedantically correct.
v2: Simplify considerably by calling fb_deferred_io_mmap() directly

drm/scheduler: Avoid accessing freed bad job.
Problem:
Due to a race between drm_sched_cleanup_jobs in sched thread and
drm_sched_job_timedout in timeout work there is a possiblity that
bad job was already freed while still being accessed from the
timeout thread.
Fix:
Instead of just peeking at the bad job in the mirror list
remove it from the list under lock and then put it back later when
we are garanteed no race with main sched thread is possible which
is after the thread is parked.
v2: Lock around processing ring_mirror_list in drm_sched_cleanup_jobs.
v3: Rebase on top of drm-misc-next. v2 is not needed anymore as
drm_sched_get_cleanup_job already has a lock there.

10 years ago, back when 32bit was still fairly common and trying to

Reality is that they simply never caught on, and nowadays everyone who
needs plenty of buffers will run in 64bit mode anyway.
Also update the docs in this area to adjust them to reality.

A few reasons to drop kmap:
- For native objects all we do is look at obj->vaddr anyway, so might
as well not call functions for every page.
- Reloc-processing on dma-buf is ... questionable.
- Plus most dma-buf that bother kernel cpu mmaps give you at least
vmap, much less kmaps. And all the ones relevant for arm-soc are
again doing a obj->vaddr game anyway, there's no real kmap going on
on arm it seems.

Gma500's struct psb_fbdev is an, otherwise empty, wrapper around
struct drm_fb_helper. Remove it.

drm/gma500: Store framebuffer in struct drm_fb_helper
The gma500 driver stores the console framebuffer in struct psb_fbdev.
Moving it into struct drm_fb_helper will allow for removal of struct
psb_fbdev.

drm/gma500: Pass struct drm_gem_object to framebuffer functions
Several framebuffer functions take a pointer to an object of type
struct gtt_range when they actually need the GEM base object. Passing
the GEM object removes some type casting and clutter.

drm/gma500: Replace struct psb_framebuffer with struct drm_framebuffer
After removing all unnecessary fields, struct psb_framebuffer is just a
wrapper around struct drm_framebuffer. So we can replace the former with
the latter.

drm/mcde: Do not needlessly logically and with 3
The i index i always 0..3 in these statements so there
is no need to tag "& 3" to clamp it to 3 here. Make
the operator precedence explicit even if it's correct
as it is, the paranthesis creates less cognitive stress
for humans.
