In such a case, a layer exceeding the max_mixer_width cannot be split, hence cannot be supported. Filter out the modes which exceed the max_mixer_width when there is no 3dmux present. Also, add a check in the dpu_crtc_atomic_check() to return failure for such modes.

Properly utilizing all planes requires the attention of the compositor, who should prefer simpler planes to YUV-supporting ones. Otherwise it is very easy to end up in a situation when all featureful planes are already allocated for simple windows, leaving no spare plane for YUV playback. To solve this problem make all planes virtual. Each plane is registered as if it supports all possible features, but then at the runtime during the atomic_check phase the driver selects backing SSPP block for each plane. As the planes are attached to the CRTC and not the encoder, the SSPP blocks are also allocated per CRTC ID (all other resources are currently allocated per encoder ID). This also matches the hardware requirement, where both rectangles of a single SSPP can only be used with the LM pair. Note, this does not provide support for using two different SSPP blocks for a single plane or using two rectangles of an SSPP to drive two planes. Each plane still gets its own SSPP and can utilize either a solo rectangle or both multirect rectangles depending on the resolution. Note #2: By default support for virtual planes is turned off and the driver still uses old code path with preallocated SSPP block for each plane. To enable virtual planes, pass 'msm.dpu_use_virtual_planes=1' kernel parameter.

Thus the whole width of two tiled multirect rectangles can not be greater than max_linewidth, which is not enough for some platforms/compositors. Another example is as simple as wide YUV plane. YUV planes can not use multirect, so currently they are limited to max_linewidth too. Now that the planes are fully virtualized, add support for allocating two SSPP blocks to drive a single DRM plane. This fixes both mentioned cases and allows all planes to go up to 2*max_linewidth (at the cost of making some of the planes unavailable to the user).

While scaling via the interconnect path was sufficient, newer GPUs like the A750 requires specific vote paremeters and bandwidth to achieve full functionality. In order to calculate vote values used by the GPU Management Unit (GMU), we need to parse all the possible OPP Bandwidths and create a vote value to be sent to the appropriate Bus Control Modules (BCMs) declared in the GPU info struct. This vote value is called IB, while on the other side the GMU also takes another vote called AB which is a 16bit quantized value of the floor bandwidth against the maximum supported bandwidth. The AB vote will be calculated later when setting the frequency. The vote array will then be used to dynamically generate the GMU bw_table sent during the GMU power-up.

Let's dynamically generate the bw_table with the vote values previously calculated from the OPPs. Those entries will then be used by the GMU when passing the appropriate bandwidth level while voting for a gpu frequency.

In order to enable bandwidth voting via the GPU Management Unit (GMU), when an opp is set by devfreq we also look for the corresponding bandwidth index in the previously generated bw_table and pass this value along the frequency index to the GMU. The GMU also takes another vote called AB which is a 16bit quantized value of the floor bandwidth against the maximum supported bandwidth. The AB is calculated with a default 25% of the bandwidth like the downstream implementation too inform the GMU firmware the minimal quantity of bandwidth we require for this OPP. Only pass the AB vote starting from A750 GPUs. Since we now vote for all resources via the GMU, setting the OPP is no more needed, so we can completely skip calling dev_pm_opp_set_opp() in this situation.
