drm/komeda: SW workaround for D71 doesn't flush shadow registers This is a SW workaround for shadow un-flushed when together with the DOU Timing-disable. D71 HW doesn't update shadow registers when display output is turned off. So when we disable all pipeline components together with display output disabling by one flush or one operation, the disable operation updated registers will not be flushed or valid in HW, which may lead problem. To workaround this problem, introduce a two phase disable for pipeline disable. Phase1: Disable components with display is on and flush it, this phase for flushing or validating the shadow registers. Phase2: Turn-off display output.

drm/komeda: Enable dual-link support Komeda HW can support dual-link which splits display frame to two halves (left/link0, right/link1) and output them by two output links. Due to the halved pixel rate of each link, the pxlclk of dual-link can be reduced two times compare with single-link. For enabling dual-link: - The DT need to configure two output-links for the pipeline node. - Komeda enable dual-link when both link0 and link1 have been connected. Example of how the pipeline node will look like for dual-link setup pipe0: pipeline@0 { clocks = <&fpgaosc2>; clock-names = "pxclk"; reg = <0>; #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; #address-cells = <1>; #size-cells = <0>; dp0_pipe0_link0: endpoint@0 { reg = <0>; remote-endpoint = <&dlink_connector_in0>; }; dp0_pipe0_link1: endpoint@1 { reg = <1>; remote-endpoint = <&dlink_connector_in1>; }; }; }; Signed-off-by: James Qian Wang (Arm Technology China) <james.qian.wang@arm.com> Signed-off-by: Liviu Dudau <Liviu.Dudau@arm.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190618081013.13638-3-james.qian.wang@arm.com

drm/komeda: Add writeback support Komeda driver uses a individual component to describe the HW's writeback caps, but drivers doesn't define a new structure and still uses the existing "struct komeda_layer" to describe this new component. The detailed changes as follow: 1. Initialize wb_layer according to HW and report it to CORE. 2. CORE exposes wb_layer as a resource to KMS by private_obj. 3. Report writeback supporting by add a wb_connector to KMS, and then wb_connector will take act as a component resources user, so the func komeda_wb_encoder_atomic_check claims komeda resources (scaler and wb_layer) accroding to its state configuration to the wb_connector. and the wb_state configuration will be validated on the specific component resources to see if the caps of component can meet the requirement of wb_connector. if not check failed. 4.
