drm/rockchip: Add reflection properties
Add the KMS plane rotation property to the DRM rockchip driver,
for SoCs RK3328, RK3368 and RK3399.
RK3288 only supports rotation at the display level (i.e. CRTC),
but for now we are only interested in plane rotation.
This commit only adds support for the value of reflect-y
and reflect-x (i.e. mirroring).
Note that y-mirroring is not compatible with YUV.
The following modetest commands would test this feature,
where 30 is the plane ID, and 49 = rotate_0 + relect_y + reflect_x.
X mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:17
Y mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:33
XY mirror:
modetest -s 43@33:1920x1080@XR24 -w 30:rotation:49

drm/rockchip: Fix YUV buffers color rendering
Currently, YUV hardware overlays are converted to RGB using
a color space conversion different than BT.601.
The result is that colors of e.g. NV12 buffers don't match

In order to fix this, enable YUV2YUV and set appropriate coefficients
for formats such as NV12 to be displayed correctly.
This commit was tested using modetest, gstreamer and chromeos (hardware
accelerated video playback). Before the commit, tests rendering
with NV12 format resulted in colors not displayed correctly.
Test examples (Tested on RK3399 and RK3288 boards

drm/fb-helper: Scale back depth to supported maximum
The following happened when migrating an old fbdev driver to DRM:
The Integrator/CP PL111 supports 16BPP but only ARGB1555/ABGR1555
or XRGB1555/XBGR1555 i.e. the maximum depth is 15.
This makes the initialization of the framebuffer fail since
the code in drm_fb_helper_single_fb_probe() assigns the same value
to sizes.surface_bpp and sizes.surface_depth. I.e. it simply assumes
a 1-to-1 mapping between BPP and depth, which is true in most cases
but not for this hardware that only support odd formats.
To support the odd case of a driver supporting 16BPP with only 15
bits of depth, this patch will make the code loop over the formats
supported on the primary plane on each CRTC managed by the FB
helper and cap the depth to the maximum supported on any primary
plane.
On the PL110 Integrator, this makes drm_mode_legacy_fb_format()
select DRM_FORMAT_XRGB1555 which is acceptable for this driver, and
thus we get framebuffer, penguin and console on the Integrator/CP.

drm/gem: Mark pinned pages as unevictable
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].

qxl: Use struct_size() in kzalloc()
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.

drm/fb-helper: fix leaks in error path of drm_fb_helper_fbdev_setup
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

drm/fb-helper: generic: Fix setup error path
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.

drm/meson: Fix an Alpha Primary Plane bug on Meson GXL/GXM SoCs
On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when
alpha is used where the alpha is not aligned with the pixel content.
The workaround Amlogic implemented is to reset the OSD1 plane hardware
block each time the plane is (re)enabled, solving the issue.
In the reset, we still need to save the content of 2 registers which
depends on the status of the plane, in addition to reload the scaler
conversion matrix at the same time.

drm/v3d: Fix prime imports of buffers from other drivers.
v3d_bo_get_pages() checks this to decide to map the imported buffer
instead of the backing shmem file. The caller was about to set this
value anyway, and there's no error path in between. Ideally we
wouldn't even allocate the shmem file for our imports, but that's a
more invasive fix.

drm/v3d: Add support for submitting jobs to the TFU.
The TFU can copy from raster, UIF, and SAND input images to UIF output
images, with optional mipmap generation. This will certainly be
useful for media EGL image input, but is also useful immediately for
mipmap generation without bogging the V3D core down.
For now we only run the queue 1 job deep, and don't have any hang
recovery (though I don't think we should need it, with TFU). Queuing
multiple jobs in the HW will require synchronizing the YUV coefficient
regs updates since they don't get FIFOed with the job.
v2: Change the ioctl to IOW instead of IOWR, always set COEF0, explain
why TFU is AUTH, clarify the syncing docs, drop the unused TFU
interrupt regs (you're expected to use the hub's), don't take
&bo->base for NULL bos.
v3: Fix a little whitespace alignment (noticed by checkpatch), rebase
on drm_sched_job_cleanup() changes.
