eab18d76b6 drm: i2c: ch7006: constify i2c_device_id
i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

44084efc2f ch7006: correctly handling failed allocation
Since drm_property_create_range can be failed in memory pressure,
it needs to be checked and return -ENOMEM.

2d13b6796e drm: encapsulate crtc->set_config calls
With refcounting we need to adjust framebuffer refcounts at each
callsite - much easier to do if they all call the same little helper
function.

0227a7fdc2 drm/i2c/ch7006: Convert to dev_pm_ops
The I2C specific suspend and resume functions have been deprecated and
printing a warning on boot for over a year, dev_pm_ops should be used
instead so convert to that.

Also remove the suspend function since all it does is log.

6ee738610f drm/nouveau: Add DRM driver for NVIDIA GPUs
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.
