2023-06-22drm/i2c: Switch i2c drivers back to use .probe()Uwe Kleine-König1-1/+1
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then commit 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2022-11-24drm/connector: Rename drm_mode_create_tv_propertiesMaxime Ripard1-1/+1
drm_mode_create_tv_properties(), among other things, will create the "mode" property that stores the analog TV mode that connector is supposed to output. However, that property is getting deprecated, so let's rename that function to mention it's deprecated. We'll introduce a new variant of that function creating the property superseeding it in a later patch.

2022-11-24drm/connector: Rename legacy TV propertyMaxime Ripard1-3/+3
The current tv_mode has driver-specific values that don't allow to easily share code using it, either at the userspace or kernel level. Since we're going to introduce a new, generic, property that fit the same purpose, let's rename this one to legacy_tv_mode to make it obvious we should move away from it.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König1-3/+1
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2019-01-11drm/ch7006: Stop using drm_crtc_force_disableDaniel Vetter1-3/+3
The correct way for legacy drivers to update properties that need to do a full modeset, is to do a full modeset. Note that we don't need to call the drm_mode_config_internal helper because we're not changing any of the refcounted paramters. v2: Fixup error handling (Ville). Since the old code didn't bother I decided to just delete it instead of adding even more code for just error handling.

2009-12-11drm/nouveau: Add DRM driver for NVIDIA GPUsBen Skeggs1-0/+531
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.
