5dbe443368 drm: omapdrm: Fix race condition between GO and vblank IRQ
The vblank interrupt is used by the driver as a completion signal when
applying new settings.

A race condition exist between enabling the vblank interrupt and
applying new settings to the hardware by setting the GO bit. If a vblank
interrupt occurs in-between, the driver will incorrectly consider the
new settings to be applied. Fix this by enabling the interrupt after
setting the GO bit.

82e58855bc drm: omapdrm: Reset the zorder property when disabling a plane
Whether to reset plane properties at disable time isn't well-defined in
DRM, but resetting only part of them is probably as bad as it can get.
Make the behaviour coherent by resetting the zorder property in addition
to the rotation property.

ef6b0e0275 drm: omapdrm: Switch to the universal plane API
Remove the CRTC private planes by switching to the universal plane API.
This results in a merge of the CRTC private plane created by the driver
(omap_crtc->plane) and the CRTC primary plane created by the DRM core
(crtc->primary).

Reference counting of the framebuffers in the update plane operation is
thus simplified as no reference needs to be stored in the private plane
anymore.

0388df0508 drm: change connector to tmp_connector
This wasn't too harmful since we already look at connector,
which has the same effect as the loop for any non-cloned configs.
Only when we have a cloned configuration is it important to look
at other connectors. Furthermore existing userspace always changes
dpms on all of them anyway.

there is a Bug that:
  vop_enable()->drm_vblank_on, drm_vblank_on may call vop
enable vblank. if it happen, vblank enable would failed,
then cause irq status error. because is_enabled value is set

after enable vop clocks and iommu regs, we can sure that
R/W vop regs and do vop plane flip is safe, so place
is_enabled = true after enable iommu is suitable.

f76c83b580 drm/rockchip: Only alloc a kmap for fbdev gem object
In general, the data in drm/rockchip GEM objects is never accessed by
the kernel.  The objects are either accessed by a GPU, by display
controller DMA, or by mmap'ing them to user space.  Thus, these
buffers need not be mapped into kernel address space.

The only exception is the fbdev framebuffer(s), which may be written
in-kernel by fbcon.

1d002fa720 drm/dp: Use large transactions for I2C over AUX
Older DisplayPort to DVI-D Dual Link adapters designed by Bizlink have bugs
in their I2C over AUX implementation (fixed in newer revisions). They work
fine with Windows, but fail with Linux.

It turns out that they cannot keep an I2C transaction open unless the
previous read was 16 bytes; shorter reads can only be followed by a zero
byte transfer ending the I2C transaction.

Copy Windows's behaviour, and read 16 bytes at a time. If we get a short
reply, assume that there's a hardware bottleneck, and shrink our read size
to match. For this purpose, use the algorithm in the DisplayPort 1.2 spec,
in the hopes that it'll be closest to what Windows does.

Also provide an unsafe module parameter for testing smaller transfer sizes,
in case there are sinks out there that cannot work with Windows.

Note also that despite the previous comment in drm_dp_i2c_xfer, this speeds
up native DP EDID reads; Ville Syrjälä <ville.syrjala@linux.intel.com> found
the following changes in his testing:

Device under test:     old  -> with this patch
DP->DVI (OUI 001cf8):  40ms -> 35ms
DP->VGA (OUI 0022b9):  45ms -> 38ms
Zotac DP->2xHDMI:      25ms ->  4ms
Asus PB278 monitor:    22ms ->  3ms

A back of the envelope calculation shows that peak theoretical transfer rate
for 1 byte reads is around 60 kbit/s; with 16 byte reads, this increases to
around 500 kbit/s, which explains the increase in speed.

c484f02d0f drm: Lighten sysfs connector 'status'
Since the beginning, sysfs/connector/status has done a heavyweight
detection of the current connector status. But no user, such as upowerd
or logind, has ever desired to initiate a probe. Move the probing into a
new attribute so that existing readers get the behaviour they desire.

v2: David Herrmann suggested using "echo detect > /sys/.../status" to
trigger the probing, which is a fine idea. This extends that to also
allow the user to apply the force detection overrides at runtime.

v3: Now with airlied's email address fixed! Requires sysfs_streq()

220dd2bc43 drm: Fixup racy refcounting in plane_force_disable
Originally it was impossible to be dropping the last refcount in this

Author: Daniel Vetter <daniel.vetter@ffwll.ch>
Date:   Wed Aug 6 09:10:18 2014 +0200

    drm: Don't grab an fb reference for the idr

we've switched to weak references, broke that assumption but forgot to
fix it up.

Since we still force-disable planes it's only possible to hit this
when racing multiple rmfb with fbdev restoring or similar evil things.
As long as userspace is nice it's impossible to hit the BUG_ON.

But the BUG_ON would most likely be hit from fbdev code, which usually
invovles the console_lock besides all modeset locks. So very likely
we'd never get the bug reports if this was hit in the wild, hence
better be safe than sorry and backport.

Commit 1da30627fc "drm: Add rotation value to
plane state" moved the rotation property to DRM core but only did the set
property part. This does the get property part as well.

    drm: Handle atomic state properly in kms getfoo ioctl

I've forgotten to remove this hunk in one of the later revisions.
drm_encoder_get_crtc already does this.

managed to pick the wrong code to resolve the conflict and left us with
a mutex_lock(struct_mutex) without the mutex_unlock(struct_mutex) leading
to a deadlock. Fix the problem by recovering the correct code which doesn't
need the lock.
