804d74abe2 drm: use drm_compat_ioctl for 32-bit apps
Most of the DRM drivers appear to be missing the .compat_ioctl file
operation entry necessary for 32-bit application compatibility.

This patch  uses drm_compat_ioctl for all drivers which don't have
their own, and which are using drm_ioctl for .unlocked_ioctl.

This leaves drivers/gpu/drm/psb/psb_drv.c unchanged; it has a custom
.unlocked_ioctl and will presumably need a custom .compat_ioctl as
well.

4ff63e47f7 Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux
Pull drm fixes from Dave Airlie:
 "Intel: edid fixes, power consumption fix, s/r fix, haswell fix

  Radeon: BIOS loading fixes for UEFI and Thunderbolt machines, better
  MSAA validation, lockup timeout fixes, modesetting fixes

  One udl dpms fix, one vmwgfx fix, a couple of trivial core changes.

  There is an export added to ACPI as part of the radeon bios fixes.

  I've also included the fbcon flashing cursor vs deinit race fix, that
  seems the simplest place to start"

Trivial conflict in drivers/video/console/fbcon.c due to me having
already applied the fbcon flashing cursor vs deinit race fix, and Dave
had added a comment in there too.

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux: (22 commits)
  fbcon: fix race condition between console lock and cursor timer (v1.1)
  drm: Add missing static storage class specifiers in drm_proc.c file

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL
drivers/gpu/drm/udl/Kconfig:1:  symbol DRM_UDL depends on USB_ARCH_HAS_HCD
drivers/usb/Kconfig:78: symbol USB_ARCH_HAS_HCD depends on USB_ARCH_HAS_OHCI
drivers/usb/Kconfig:16: symbol USB_ARCH_HAS_OHCI depends on I2C
drivers/i2c/Kconfig:5:  symbol I2C is selected by FB_DDC
drivers/video/Kconfig:86:       symbol FB_DDC is selected by FB_CYBER2000_DDC
drivers/video/Kconfig:385:      symbol FB_CYBER2000_DDC depends on FB_CYBER2000
drivers/video/Kconfig:373:      symbol FB_CYBER2000 depends on FB

which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
	...
	default y if ARCH_PNX4008 && I2C

Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL

drivers/gpio/Kconfig:35:        symbol GPIOLIB is selected by FB_VIA
drivers/video/Kconfig:1560:     symbol FB_VIA depends on FB

which can be fixed by having MFD_TC6393XB select GPIOLIB instead of depending on
it.

d42f0349f3 drm/udl: Make sure to get correct endian keys from vendor descriptor
This is a port of
commit b49f184b64
Author: Ben Collins <bcollins@ubuntu.com>
from udlfb to udl kms driver.

The driver was not using le16_to_cpu when reading keys from the vendor
descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not
being parsed on big-endian systems. This would result in a blank screen
on big-endian CPUs where the DL chips's max mode was smaller than the
monitor's native mode.

5320918b9a drm/udl: initial UDL driver (v4)
This is an initial drm/kms driver for the displaylink devices.

Supports fb_defio,
supports KMS dumb interface
supports 24bpp via conversion to 16bpp, hw can do this better.
supports hot unplug using new drm core features.

On an unplug, it disables connector polling, unplugs connectors
from sysfs, unplugs fbdev layer (using Kay's API), drops all the
USB device URBs, and call the drm core to unplug the device.

This driver is based in large parts on udlfb.c so I've licensed
it under GPLv2.
