* drm/rockchip: Add VOP2 driverAndy Yan2022-05-041-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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_encoderSascha Hauer2022-05-031-1/+3
| | | | | | | | | | | | | | | | | | | 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_decoderSascha Hauer2022-05-031-0/+10
| | | | | | | | | | | | | | | | | | | 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 initialisationRobin Murphy2022-05-021-0/+3
| | | | | | | | | | | | | 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: get rid of rockchip_drm_crtc_mode_configMark Yao2016-05-031-2/+8
| | | | | | | | | | | | We need to take care of the vop status when use rockchip_drm_crtc_mode_config, if vop is disabled, the function would failed, that is terrible. Save output_type and output_mode into rockchip_crtc_state, it's nice to make them into atomic. Signed-off-by: Mark Yao <mark.yao@rock-chips.com> Tested-by: John Keeping <john@metanate.com>
* drm/rockchip: cancel pending vblanks on closeJohn Keeping2016-03-281-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | When closing the DRM device while a vblank is pending, we access file_priv after it has been free'd, which gives: Unable to handle kernel NULL pointer dereference at virtual address 00000000 ... PC is at __list_add+0x5c/0xe8 LR is at send_vblank_event+0x54/0x1f0 ... [<c02952e8>] (__list_add) from [<c031a7b4>] (send_vblank_event+0x54/0x1f0) [<c031a760>] (send_vblank_event) from [<c031a9c0>] (drm_send_vblank_event+0x70/0x78) [<c031a950>] (drm_send_vblank_event) from [<c031a9f8>] (drm_crtc_send_vblank_event+0x30/0x34) [<c031a9c8>] (drm_crtc_send_vblank_event) from [<c0339ad8>] (vop_isr+0x224/0x28c) [<c03398b4>] (vop_isr) from [<c0081780>] (handle_irq_event_percpu+0x12c/0x3e4) This can be triggered somewhat reliably with: modetest -M rockchip -v -s ... Add a preclose hook to the driver so that we can discard any pending vblank events when the device is closed. Signed-off-by: John Keeping <john@metanate.com>
