2023-03-14drm/fbdev-dma: Implement fbdev emulation for GEM DMA helpersThomas Zimmermann
Implement fbdev emulation that is optimized for drivers that use DMA helpers. The buffers may no tbe moveable, may not require damage handling and have to be located in system memory. This allows fbdev emulation to operate directly on the buffer and mmap it to userspace. Besides those constraints, the emulation works like in the generic code. As an internal DRM client provides, it receives hotplug, restore and unregister events. The DRM client is independent from the fbdev probing, which runs on the first successful hotplug event. The emulation is part of the DMA helper module and not build unless DMA helpers and fbdev emulation has been configured. Tested with vc4.

2023-03-13drm/cirrus: Enable damage clipping on primary planeThomas Zimmermann
Enable damage clipping on the primary plane and iterate over small areas of reported framebuffer damage. Avoid the overhead of permanent full-screen updates that cirrus currently implements. This problem is indicated by the warning drm_plane_enable_fb_damage_clips() not called in the kernel's log. Without damage clipping, drivers do full updates of the screen area. This is costly as many screen updates, such as cursor movement or command-line input, only change a small portion of the output. Damage clipping allows renderers to inform drivers about the changed areas. With the damage information known, cirrus now iterates over a list of change areas and only flushes those to the hardware's scanout buffer.

2023-03-13drm/cirrus: Convert to regular atomic helpersThomas Zimmermann
Replace simple-KMS helpers with DRM's regular helpers for atomic modesetting. Avoids the mid-layer and the additional wrappers around GEM's shadow-plane helpers. Most of the simple-KMS code is just wrappers around regular atomic helpers. The conversion is therefore equivalent to pulling the simple-KMS helpers into cirrus and removing all the intermediate code and data structures between the driver and the atomic helpers. As the simple-KMS helpers lump primary plan, CRTC and encoder into a single data structure, the conversion to regular helpers allows to split modesetting from plane updates and handle each individually.

2023-03-09drm/rockchip: dw_hdmi: relax mode_valid hookSascha Hauer
The driver checks if the pixel clock of the given mode matches an entry in the mpll config table. At least for the Synopsys phy the frequencies in the mpll table are meant as a frequency range up to which the entry works, not as a frequency that must match the pixel clock. Return MODE_OK when the pixelclock is smaller than one of the mpll frequencies to allow for more display resolutions. Limit this behaviour to the Synopsys phy at the moment and keep the current behaviour of forcing exact pixelclock rates for the other phys until it has been sorted out how and if the vendor specific phys work with non standard clock rates.

2023-03-09drm/rockchip: vop: limit maximum resolution to hardware capabilitiesSascha Hauer
The different VOP variants support different maximum resolutions. Reject resolutions that are not supported by a specific variant. This hasn't been a problem in the upstream driver so far as 1920x1080 has been the maximum resolution supported by the HDMI driver and that resolution is supported by all VOP variants. Now with higher resolutions supported in the HDMI driver we have to limit the resolutions to the ones supported by the VOP. The actual maximum resolutions are taken from the Rockchip downstream Kernel.

2023-03-07gpu/drm/panel: Add Sony TD4353 JDI panel driverKonrad Dybcio
Add support for the Sony TD4353 JDI 2160x1080 display panel used in some Sony Xperia XZ2 and XZ2 Compact smartphones. Due to the specifics of smartphone manufacturing, it is impossible to retrieve a better name for this panel. This revision adds support for the default 60 Hz configuration, however there could possibly be some room for expansion, as the display panels used on Sony devices have historically been capable of >2x refresh rate overclocking.
