drm/rockchip: move output interface related definition to rockchip_drm_drv.h

2023-12-13T14:17:44+00:00

The output interface related definition can shared between
vop and vop2, move them to rockchip_drm_drv.h can avoid duplicated
definition.

drm/fb-helper: Remove unnecessary include statements

2022-11-05T16:12:04+00:00

Remove include statements for  where it is not
required (i.e., most of them). In a few places include other header
files that are required by the source code.

v3:
	* fix amdgpu include statements
	* fix rockchip include statements

drm/rockchip: Add VOP2 driver

2022-05-04T12:05:47+00:00

The VOP2 unit is found on Rockchip SoCs beginning with rk3566/rk3568.
It replaces the VOP unit found in the older Rockchip SoCs.

This driver has been derived from the downstream Rockchip Kernel and
heavily modified:

- All nonstandard DRM properties have been removed
- dropped struct vop2_plane_state and pass around less data between
  functions
- Dropped all DRM_FORMAT_* not known on upstream
- rework register access to get rid of excessively used macros
- Drop all waiting for framesyncs

The driver is tested with HDMI and MIPI-DSI display on a RK3568-EVB
board. Overlay support is tested with the modetest utility. AFBC support
on the cluster windows is tested with weston-simple-dmabuf-egl on
weston using the (yet to be upstreamed) panfrost driver support.

drm/rockchip: Add crtc_endpoint_id to rockchip_encoder

2022-05-03T09:24:00+00:00

The VOP2 has an interface mux which decides to which encoder(s) a CRTC
is routed to. The encoders and CRTCs are connected via of_graphs in the
device tree. When given an encoder the VOP2 driver needs to know to
which internal register setting this encoder matches. For this the VOP2
binding offers different endpoints, one for each possible encoder. The
endpoint ids of these endpoints are used as a key from an encoders
device tree description to the internal register setting.

This patch adds the key aka endpoint id to struct rockchip_encoder plus
a function to read the endpoint id starting from the encoders device
node.

drm/rockchip: Embed drm_encoder into rockchip_decoder

2022-05-03T09:23:47+00:00

The VOP2 driver needs rockchip specific information for a drm_encoder.

This patch creates a struct rockchip_encoder with a struct drm_encoder
embedded in it. This is used throughout the rockchip driver instead of
struct drm_encoder directly.

The information the VOP2 drivers needs is the of_graph endpoint node
of the encoder. To ease bisectability this is added here.

While at it convert the different encoder-to-driverdata macros to
static inline functions in order to gain type safety and readability.

drm/rockchip: Refactor IOMMU initialisation

2022-05-02T21:52:27+00:00

Defer the IOMMU domain setup until after successfully binding
components, so we can figure out IOMMU support directly from the VOP
devices themselves, rather than manually inferring it from the DT (which
also fails to account for whether the IOMMU driver is actually loaded).
Although this is somewhat of a logical cleanup, the main motivation is
to prepare for a change in the iommu_domain_alloc() interface.

drm/rockchip: use generic fbdev setup

The Rockchip fbdev code does not add anything compared to
drm_fbdev_generic_setup(); the one custom function for .fb_mmap does the
same thing as gem_prime_mmap which is called by the helper.
