2019-11-12drm/komeda: Optionally dump DRM state on interruptsMihail Atanassov
It's potentially useful information when diagnosing error/warn IRQs, so dump it to dmesg with a drm_info_printer. Hide this extra debug dumping behind another komeda_dev->err_verbosity bit. Note that there's not much sense in dumping it for INFO events, since the VSYNC event will swamp the log.

2019-10-01drm/komeda: Workaround for broken FLIP_COMPLETE timestampsMihail Atanassov
When initially turning a crtc on, drm_reset_vblank_timestamp will set the vblank timestamp to 0 for any driver that doesn't provide a ->get_vblank_timestamp() hook. Unfortunately, the FLIP_COMPLETE event depends on that timestamp, and the only way to regenerate a valid one is to have vblank interrupts enabled and have a valid in-ISR call to drm_crtc_handle_vblank. Additionally, if the user doesn't request vblanks but _does_ request FLIP_COMPLETE events, we still don't have a good timestamp: it'll be the same stamp as the last vblank one. Work around the issue by always enabling vblanks when the CRTC is on. Reducing the amount of time that PL0 has to be unmasked would be nice to fix at a later time.

2019-09-27drm/komeda: SW workaround for D71 doesn't flush shadow registersLowry Li (Arm Technology China)
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.

2019-08-02drm/komeda: Enable dual-link supportjames qian wang (Arm Technology China)
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
