"This seems to have been a comparatively quieter merge window, I assume
due to holidays etc. The "biggest" change is AMD header cleanups, which
merge/remove a bunch of them. The AMD gpu scheduler is now being made generic
with the etnaviv driver wanting to reuse the code, hopefully other drivers
can go in the same direction.
Otherwise it's the usual lots of stuff in i915/amdgpu, not so much stuff
elsewhere.

It is misleading to call a functional resource a "device". In adopting
the Linux Driver Model, the struct device will be embedded in struct
nubus_board. That will compound the terminlogy problem because drivers
will bind with boards, not with functional resources. Avoid this by
renaming struct nubus_dev as struct nubus_rsrc. "Functional resource"
is the vendor's terminology so this helps avoid confusion.

Currently the LCD display (TD035S) on the cm-x300 platform is broken and
remains blank.
The TD0245S specification requires that the chipselect is toggled
between commands sent to the panel. This was also the purpose of the
former patch of commit f64dcac0b124 ("backlight: tdo24m: ensure chip
select changes between transfers").
Unfortunately, the "cs_change" field of a SPI transfer is
misleading. Its true meaning is that for a SPI message holding multiple
transfers, the chip select is toggled between each transfer, but for the
last transfer it remains asserted.
In this driver, all the SPI messages contain exactly one transfer, which
means that each transfer is the last of its message, and as a
consequence the chip select is never toggled.
Actually, there was a second bug hidding the first one, hence the
problem was not seen until v4.6. This problem was fixed by commit
a52db659c79c ("spi: pxa2xx: Fix cs_change management") for PXA based
boards.
This fix makes the TD035S work again on a cm-x300 board. The same
applies to other PXA boards, ie. corgi and tosa.

Set the resource type when we reserve VGA-related I/O port resources.
The resource code doesn't actually look at the type, so it inserts
resources without a type in the tree correctly even without this change.
But if we ever print a resource without a type, it looks like this:
vga+ [??? 0x000003c0-0x000003df flags 0x0]
Setting the type means it will be printed correctly as:
vga+ [io 0x000003c0-0x000003df]

On some hardware the LCD panel is not mounted upright in the casing,
but rotated by 90 degrees. In this case we want the console to
automatically be rotated to compensate.
The drm subsys has a quirk table for this, use the
drm_get_panel_orientation_quirk function to get the panel orientation
and set info->fbcon_rotate_hint based on this, so that the fbcon console
on top of efifb gets automatically rotated to compensate for the panel
orientation.

On some hardware the LCD panel is not mounted upright in the casing,
but upside-down or rotated 90 degrees. In this case we want the console
to automatically be rotated to compensate.
The fbdev-driver may know about the need to rotate. Add a new
fbcon_rotate_hint field to struct fb_info, which gets initialized to -1.
If the fbdev-driver knows that some sort of rotation is necessary then
it can set this field to a FB_ROTATE_* value to tell the fbcon console
driver to rotate the console.

HDMI 2.0 Appendix F suggest that we should keep sending the infoframe
when switching from 3D to 2D mode, even if the infoframe isn't strictly
necessary (ie. not needed to transmit the VIC or stereo information).
This is a workaround against some sinks that fail to realize that they
should switch from 3D to 2D mode when the source stop transmitting
the infoframe.

The pointer fbi is dereferenced with par = fbi->par before there is a
null check on fbi, hence there is a potential null pointer dereference
on a null par. Fix this by moving the dereference after the null
pointer check.

During console takeover, which happens for all DRM/KMS setups using the
fbdev helpers, fbcon_startup() is called before fbcon_init() and as a
result con2fb_acquire_newinfo() will not be called (info->fbcon_par was
set to non-NULL in fbcon_startup()) to assign ops->info.
This causes the cursor_timer_handler() to unreference a NULL pointer.
Avoid this by unconditionally assigning ops->info during fbcon_startup()
so that it will be available early, but keep the additional assignment
in con2fb_acquire_newinfo() to support console remapping at runtime.

Dan's static analysis says:
drivers/video/fbdev/controlfb.c:560 control_setup()
error: buffer overflow 'control_mac_modes' 20 <= 21
Indeed, control_mac_modes[] has only 20 elements, while VMODE_MAX is 22,
which may lead to an out of bounds read when parsing vmode commandline
options.
The bug was introduced in v2.4.5.6, when 2 new modes were added to
macmodes.h, but control_mac_modes[] wasn't updated:
https://kernel.opensuse.org/cgit/kernel/diff/include/video/macmodes.h?h=v2.5.2&id=29f279c764808560eaceb88fef36cbc35c529aad
Augment control_mac_modes[] with the two new video modes to fix this.

The PIXDATA flags of the display_flags enum are controller centric,
e.g. NEGEDGE means the controller shall drive the data signals on
pixelclocks negative edge. However, the drivers flag is display
centric: Sample the data on negative (falling) edge.
Therefore, change the if statement to check for the POSEDGE flag
(which is typically not set):
Drive on positive edge => sample on negative edge

Rewrite the exit path based on 'au1200fb_drv_remove()'.
We can safely iterate for all already handled planes. Even if not
completely initialized, the functions that are called will silently accept
the 'fb_info' structure that is passed.
As soon as we find a NULL in the '_au1200fb_infos' array, we know that we
have released all what we needed to release. So we can 'break'.

'au1200fb_drv_probe()' can not fail after a successful call to
'request_irq()'. So there is no point to call 'free_irq()' in the error
handling path.
Moreover, the hard coded AU1200_LCD_INT looks boggus since
commit 1630d85a8312 ("au1200fb: fix hardcoded IRQ").
So, remove it.
