Make life easier for drivers by simply passing the connector
to drm_hdmi_avi_infoframe_from_display_mode() and
drm_hdmi_avi_infoframe_quant_range(). That way drivers don't
need to worry about is_hdmi2_sink mess.
v2: Make is_hdmi2_sink() return true for sil-sii8620
Adapt to omap/vc4 changes

drmP.h was the only header file in the past and a lot
of files rely on that drmP.h defines everything.
The goal is to one day to delete drmP.h and
as a step towards this it will no longer be included in the
headers files in include/drm/
To prepare tinydrm/ for this add dependencies that
othwewise was pulled in by drmP.h from drm_gem_cma_helper.h
To avoid that tinydrm.h became "include everything",
push include files to the individual drivers.

drmP.h is an relic from the days when there was a single header file.
To enable the removal of drmP.h from all users drop include
of drmP.h from bridge/dw_hdmi.h.
A few files relied on the file included in drmP.h - add explicit
include statements or forward declarations to these files.
Build tested with arm and x86.
v2:
- prefer forward declarations when possible (Laurent Pinchart)
- sort include files (Laurent Pinchart)

The gem drivers use shmemfs to allocate backing storage for gem objects.
On Samsung Chromebook Plus, the drm/rockchip driver may call
rockchip_gem_get_pages -> drm_gem_get_pages -> shmem_read_mapping_page
to pin a lot of pages, breaking the page reclaim mechanism and causing
oom-killer invocation.
E.g. when the size of a zone is 3.9 GiB, the inactive_ratio is 5. If
active_anon / inactive_anon < 5 and all pages in the inactive_anon lru
are pinned, page reclaim would keep scanning inactive_anon lru without
reclaiming memory. It breaks page reclaim when the rockchip driver only
pins about 1/6 of the anon lru pages.
Mark these pinned pages as unevictable to avoid the premature oom-killer
invocation. See also similar patch on i915 driver [1].

One of the more common cases of allocation size calculations is finding the
size of a structure that has a zero-sized array at the end, along with memory
for some number of elements for that array. For example:
struct foo {
int stuff;
void *entry[];
};
instance = kzalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can now
use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL);
This code was detected with the help of Coccinelle.

After drm_fb_helper_fbdev_setup calls drm_fb_helper_init,
"dev->fb_helper" will be initialized (and thus drm_fb_helper_fini will
have some effect). After that, drm_fb_helper_initial_config is called
which may call the "fb_probe" driver callback.
This driver callback may call drm_fb_helper_defio_init (as is done by
drm_fb_helper_generic_probe) or set a framebuffer (as is done by bochs)
as documented. These are normally cleaned up on exit by
drm_fb_helper_fbdev_teardown which also calls drm_fb_helper_fini.
If an error occurs after "fb_probe", but before setup is complete, then
calling just drm_fb_helper_fini will leak resources. This was triggered
by df2052cc922 ("bochs: convert to drm_fb_helper_fbdev_setup/teardown"):

If register_framebuffer() fails during fbdev setup we will leak the
framebuffer, the GEM buffer and the shadow buffer for defio. This is
because drm_fb_helper_fbdev_setup() just calls drm_fb_helper_fini() on
error not taking into account that register_framebuffer() can fail.
Since the generic emulation uses DRM client for its framebuffer and
backing buffer in addition to a shadow buffer, it's necessary to open code
drm_fb_helper_fbdev_setup() to properly handle the error path.
Error cleanup is removed from .fb_probe and is handled by one function for
all paths.

The drm_mode_create_tile_group() is only called from
drm_parse_tiled_block() and the caller expects it to return a NULL on
error. In other words, this function should match
drm_mode_get_tile_group().

This:
- Adds local variables in the first loop, instead of using array indices
everywhere
- Adds an early continue to reduce the indent level in the second loop
There should be no functional changes here

We need to call drm_dp_mst_topology_mgr_set_mst(mgr, false) when
destroying the topology manager in order to ensure that the root mstb
and all of it's descendents are actually destroyed, and additionally to
try to make sure that we leave the hub in a clean state.

This patch solves this TODO task:

Render like lima will attach a fence to the framebuffer dma_buf,
so the display driver should wait for it to finish before showing
the framebufferto prevent tearing.
Generally tested on rk3188, rk3288, rk3328 and rk3399 and
together with an actual lima-based kmscube on rk3188 and rk3328.

Make sure i2c msgs we're asked to transfer conform to the
requirements of REMOTE_I2C_READ. We were only checking that the
last message is a read, but we must also check that the preceding
messages are all writes. Also check that the length of each
message isn't too long.

We aren't supposed to force a stop+start between every i2c msg
when performing multi message transfers. This should eg. cause
the DDC segment address to be reset back to 0 between writing
the segment address and reading the actual EDID extension block.
To quote the E-DDC spec:
"... this standard requires that the segment pointer be
reset to 00h when a NO ACK or a STOP condition is received."
Since we're going to touch this might as well consult the
I2C_M_STOP flag to determine whether we want to force the stop
or not.

When everyone implements it exactly the same way, among all 4
implementations, there's not really a need to overwrite this at all.
Aside: drm_kms_helper_hotplug_event is pretty much core functionality
at this point. Probably should move it there.
