Fix a bug that was introduced in commit c4c11dd1 ("drm/i2c: tda998x:
add video and audio input configuration") when Sebastian cleaned up my
original patch.  Without this being fixed, audio is muted when the
display is turned off, never to be re-enabled.

Some LCD controller cannot provide valid VESA style sync, i.e. coincident
HS/VS edges. First, this patch adds hskew passed from the adjusted_mode to
reference pixel calculation to allow those controllers to add an offset
relative to the expected reference pixel.

The video-input-port (VIP) is highly configurable. This prepares
current driver to allow to configure VIP configuration, as some
boards connect lcd controller and TDA998x "pin-swapped" and depend
on VIP to swap the pins by register configuration.

When switching between various drivers for this device, it's possible
that some critical registers are left containing values which affect
the device operation.  One such case encountered is the VIP output
mux register.  This defaults to 0x24 on powerup, but other drivers may
set this to 0x12.  This results in incorrect colours.

Fix this by ensuring that the register is always set to the power on
default setting.

With refcounting we need to adjust framebuffer refcounts at each

This adds a drm/kms staging non-API stable driver for GPUs from NVIDIA.

This driver is a KMS-based driver and requires a compatible nouveau
userspace libdrm and nouveau X.org driver.

This driver requires firmware files not available in this kernel tree,
interested parties can find them via the nouveau project git archive.

This driver is reverse engineered, and is in no way supported by nVidia.

Support for nearly the complete range of nvidia hw from nv04->g80 (nv50)
is available, and the kms driver should support driving nearly all
output types (displayport is under development still) along with supporting
suspend/resume.

This work is all from the upstream nouveau project found at
nouveau.freedesktop.org.
