The mgag200 driver now uses managed functions for DRM devices. The individual helpers for modesetting and memory managed are already covered, so only device allocation and initialization is left for conversion. Signed-off-by:

Following current best practice, the instance of struct drm_device is now embedded in struct mga_device. The respective field has been renamed from 'dev' to 'base' to reflect the relationship. Conversion from DRM device is done via upcast. Using dev_private is no longer possible. The patch also open-codes drm_dev_alloc() and DRM device initialization is now performed by a call to drm_device_init(). Signed-off-by:

Instances of struct drm_device and struct mga_device are now allocated next to each other in mgag200_driver_load(). Yet another preparation before embedding the DRM device instance in struct mga_device. Signed-off-by:

Embedding the DRM device instance in struct mga_device will require changes to device allocation. Moving the device initialization into its own functions gets it out of the way. Signed-off-by:

So far the plane creation was done when each CRTC was bound, and those planes were only tied to the CRTC that was registering them. This causes two main issues: - The planes in the vc4 hardware are actually not tied to any CRTC, but can be used with every combination - More importantly, so far, we allocate 10 planes per CRTC, with 3 CRTCs. However, the next generation of hardware will have 5 CRTCs, putting us well above the maximum of 32 planes currently allowed by DRM. This patch is the first one in a series of patches that will take down both of these issues so that we can support the next generation of hardware while keeping a good amount of planes. We start by changing the way the planes are registered to first registering the primary planes for each CRTC in the CRTC bind function as we used to, but moving the overlay and cursor creation to the main driver bind function, after all the CRTCs have been bound, and make the planes associated to all CRTCs. This will slightly change the ID order of the planes, since the primary planes of all CRTCs will be first, and then a pattern of 8 overlays, 1 cursor plane for each CRTC. This shouldn't cause any trouble since the ordering between the planes is preserved though. Reviewed-by: -

The planes so far were created as part of the CRTC binding code with each planes created associated only to one CRTC. However, the hardware in the vc4 doesn't really have such constraint and can be used with any CRTC. In order to rework this, let's first move the overlay and cursor planes creation to a function of its own. Reviewed-by:

vc4_drv.h doesn't have any include guards which prevents it from being included twice. Let's add them. Reviewed-by:

The BCM283x SoCs have a display pipeline composed of several controllers with device tree bindings that are supported by Linux. Now that we have the DT validation in place, let's split into separate files and convert the device tree bindings for those controllers to schemas. This is just a 1:1 conversion though, and some bindings were incomplete so it results in example validation warnings that are going to be addressed in the following patches. Acked-by:

The udl driver contains an implementation of GEM vmap and mmap operations that is identical to the common SHMEM helper; except that udl's code uses cached pages by default. Convert udl to regular SHMEM helper functions. There's no reason to have udl behave differently from all other SHMEM drivers. The udl driver uses the SHMEM helper to enable caching. v3: * rebased onto Daniel's shmem untangle series v2: * implement .gem_create_object with SHMEM helper Signed-off-by:
