The RaspberryPi4 has both a WiFi chip and HDMI outputs capable of doing 4k. Unfortunately, the 1440p resolution at 60Hz has a TMDS rate on the HDMI cable right in the middle of the first Wifi channel. Add a property to our HDMI controller, that could be reused by other similar HDMI controllers, to allow the OS to take whatever measure is necessary to avoid that crosstalk. Signed-off-by:

The FIFO between the pixelvalve and the HDMI controller runs at 2 pixels per clock cycle, and cannot deal with odd timings. Let's reject any mode with such timings. Signed-off-by:

The HDMI controller cannot go above a certain pixel rate limit depending on the generations, but that limit is only enforced in mode_valid at the moment, which means that we won't advertise modes that exceed that limit, but the userspace is still free to try to setup a mode that would. Implement atomic_check to make sure we check it in that scenario too. Signed-off-by:

Commit e0d07278 ("dma-mapping: introduce DMA range map, supplanting dma_pfn_offset") introduced a regression in our code since the second backed to probe will now get -EINVAL back from dma_direct_set_offset and will prevent the entire DRM device from probing.

It has been observed that resetting force in the detect function can result in the PHY being powered down in response to hot-plug detect being asserted, even when the HDMI connector is forced on.

When unloading the call to pm_runtime_put_sync_suspend() will attempt to turn the GPU cores off, however panfrost_device_fini() will have turned the clocks off. This leads to the hardware locking up. Instead don't call pm_runtime_put_sync_suspend() and instead simply mark the device as suspended using pm_runtime_set_suspended(). And also include this on the error path in panfrost_probe().

The fixes are for some reported issues in the interconnect and coresight drivers, nothing major. The "big" driver removal is the MIC drivers have been asked to be removed as the hardware never shipped and Intel no longer wants to maintain something that no one can use. This is welcomed by many as the DMA usage of these drivers was "interesting" and the security people were starting to question some issues that were starting to be found in the codebase. Note, one of the subsystems for this driver, the "VOP" code, will probably come back in future kernel versions as it was looking to potentially solve some PCIe virtualization issues that a number of other vendors were wanting to solve.
