Other properties are documented with a colon character after the
property name. Consistently using a colon character allows the docs to
be machine-readable.

The drivers gm12u320 and udl operate on USB devices. They leave the PCI
device in struct drm_device empty and store the USB device in their own

DRM drivers for USB devices can share a few helpers. It's currently only
a function to retrieve the USB device's structure from the DRM device.
Putting this code next to the DRM device would make all of DRM depend on
USB headers. So it's in a separate header file.

omapdrm supports gamma via GAMMA_LUT property. However, the HW we have
is:
gamma -> ctm -> out
instead of what the model DRM framework uses:
ctm -> gamma -> out
As the following patches add CTM support for omapdrm, lets first fix the
gamma.
This patch changes the property from GAMMA_LUT to DEG
We currently have drm_atomic_helper_legacy_gamma_set() helper which can
be used to handle legacy gamma-set ioctl.
drm_atomic_helper_legacy_gamma_set() sets GAMMA_LUT, and clears
CTM and DEGAMMA_LUT. This works fine on HW where we have either:
degamma -> ctm -> gamma -> out
or

This is a basic KMS atomic modesetting display driver for KeemBay family of
SOCs. Driver has no 2D or 3D graphics. It calls into the ADV bridge
driver at the connector level.
Single CRTC with LCD controller->mipi DSI->ADV bridge
Only 1080p resolution and single plane is supported at this time.

Nouveau does not currently support hot-unplugging, but it still makes
sense to switch from drm_dev_unregister() to drm_dev_unplug().
drm_dev_unplug() calls drm_dev_unregister() after marking the device as
unplugged, but only after any device critical sections are finished.
Since nouveau isn't usin
The postclose handler can run after the device has been removed (or the
driver has been unbound) since userspace clients are free to hold the
file open the file as long as they want. Because the device removal
callback frees the entire nouveau_drm structure, any reference to it in
the postclose han
Rather than protecting the nouveau_drm clients list with the lock within
the "client" nouveau_cli, add a dedicated lock to serialize access to
the list. This is both clearer and necessary to avoid lockdep being
upset with us when we need to iterate through all the clients in the
list and potentiall
This series fixes a number of use-after-frees in nouveau's postclose()
handler. It was discovered by pointing IGT's core_hotunplug tests at a
nouveau device, but the steps to reproduce it are simple:
1. Open the device file
2. Unbind the driver or remove the device
3. Close the file opened in step

commit f49a51bfdc8ea717c97ccd4cc98b7e6daaa5553a upstream.
When we forward an mmap to the dma_buf exporter, they get to own
everything. Unfortunately drm_gem_mmap_obj() overwrote
vma->vm_private_data after the driver callback, wreaking the

Use the per device drm driver feature flags rather than the
global one. This way we can make the drm driver struct const.

Noticed this when trying to compile with -Wall on a kernel fork. We potentially
don't set width here, which causes the compiler to complain about width
potentially being uninitialized in drm_cvt_modes(). So, let's fix that.
