2019-10-18drm/edid: Fix HDMI VIC handlingVille Syrjälä1-16/+21
Extract drm_mode_hdmi_vic() to correctly calculate the final HDMI VIC for us. Currently this is being done a bit differently between the AVI and HDMI infoframes. Let's get both to agree on this. We need to allow the case where a mode is both 3D and has a HDMI VIC. Currently we'll just refuse to generate the HDMI infoframe when we really should be setting HDMI VIC to 0 and instead enabling 3D stereo signalling. If the sink doesn't even support the HDMI infoframe we should not be picking the HDMI VIC in favor of the CEA VIC, because then we'll end up not sending either VIC in the end.

2019-10-17drm: add mmap() to drm_gem_object_funcsGerd Hoffmann3-9/+41
drm_gem_object_funcs->vm_ops alone can't handle everything which needs to be done for mmap(), tweaking vm_flags for example. So add a new mmap() callback to drm_gem_object_funcs where this code can go to. Note that the vm_ops field is not used in case the mmap callback is present, it is expected that the callback sets vma->vm_ops instead. Also setting vm_flags and vm_page_prot is the job of the new callback. so drivers have more control over these flags. drm_gem_mmap_obj() will use the new callback for object specific mmap setup. With this in place the need for driver-speific fops->mmap callbacks goes away, drm_gem_mmap can be hooked instead. drm_gem_prime_mmap() will use the new callback too to just mmap gem objects directly instead of jumping though loops to make drm_gem_object_lookup() and fops->mmap work.

LT-tunable PHY Repeaters can operate in two different modes: transparent (default) and non-transparent. The value 0x55 specifies the transparent mode, and 0xaa represents the non-transparent; this commit adds these two values as definitions.

2019-10-15drm/bridge: dw-hdmi: Restore audio when setting a modeDaniel Kurtz1-1/+1
When setting a new display mode, dw_hdmi_setup() calls dw_hdmi_enable_video_path(), which disables all hdmi clocks, including the audio clock. We should only (re-)enable the audio clock if audio was already enabled when setting the new mode. Without this patch, on RK3288, there will be HDMI audio on some monitors if i2s was played to headphone when the monitor was plugged. ACER H277HU and ASUS PB278 are two of the monitors showing this issue.

2019-10-14drm/mxsfb: Update mxsfb to support a bridgeRobert Chiras4-21/+72
Currently, the MXSFB DRM driver only supports a panel. But, its output display signal can also be redirected to another encoder, like a DSI controller. In this case, that DSI controller may act like a drm_bridge. In order support this use-case too, this patch adds support for drm_bridge in mxsfb.
