2020-09-22drm: rcar-du: Fix crash when enabling a non-visible planeLaurent Pinchart1-1/+1
The DU driver handles non-visible planes (fully clipped by the display's boundaries) by considering them as disabled. It thus disables the plane at the hardware level when the plane is moved off-screen. However, if the plane was previously disabled and is non-visible when it gets enabled, the attempt to disable it crashes, as the plane wasn't previously enabled. Fix it.

2020-09-21drm/vc4: hvs: Pull the state of all the CRTCs prior to PV muxingMaxime Ripard1-0/+17
The vc4 display engine has a first controller called the HVS that will perform the composition of the planes. That HVS has 3 FIFOs and can therefore compose planes for up to three outputs. The timings part is generated through a component called the Pixel Valve, and the BCM2711 has 6 of them. Thus, the HVS has some bits to control which FIFO gets output to which Pixel Valve. The current code supports that muxing by looking at all the CRTCs in a new DRM atomic state in atomic_check, and given the set of constraints that we have, assigns FIFOs to CRTCs or reject the mode entirely. The actual muxing will occur during atomic_commit. However, that doesn't work if only a fraction of the CRTCs' state is updated in that state, since it will ignore the CRTCs that are kept running unmodified, and will thus unassign its associated FIFO, and later disable it. In order to make the code work as expected, let's pull the CRTC state of all the enabled CRTC in our atomic_check so that we can operate on all the running CRTCs, no matter whether they are affected by the new state or not.

2020-09-18drm: bridge: Add support for Cadence MHDP8546 DPI/DP bridgeSwapnil Jakhade6-0/+2938
Add a new DRM bridge driver for Cadence MHDP8546 DPTX IP used in TI J721E SoC. MHDP DPTX IP is the component that complies with VESA DisplayPort (DP) and embedded Display Port (eDP) standards. It integrates uCPU running the embedded Firmware (FW) interfaced over APB interface. Basically, it takes a DPI stream as input and outputs it encoded in DP format. Currently, it supports only SST mode.
