Gives us proper nonblocking support for free, and a pile of other things. The tilcdc code is simply old enough that it was never converted over, but was stuck forever with the copypasta from when it was initially merged. The riskiest thing with this conversion is maybe that there's an issue with the vblank handling or vblank event handling, which will upset the modern commit support in atomic helpers. But from a cursory review drm_crtc_vblank_on/off is called in the right places, and the event handling also seems to exist (albeit with much hand-rolling and probably some races, could perhaps be converted over to drm_crtc_arm_vblank_event without any real loss). Motivated by me not having to hand-roll the dma-fence annotations for this. v2: Clear out crtc_state->event when we're handling the event, to avoid upsetting the helpers (reported by Jyri). v3: Also send out even whent the crtc is getting disabled. Tilcdc looks a bit like conversion to simple display helpers would work out really nice. Tested-by:

Of the DPMS code, only ON and OFF states are used. Simplify mode setting by moving both into separate functions and removing the rest. The original code busy waited in the middle of updating the screen state in SEQ1. To simplify the procedure, the new code busy waits first and then updates SEQ1 in one chunk. The DPMS code also set the LUT before enabling the screen. The patch moves this code into the simple-display pipe's enable function. v2: * comment on SEQ1 updates in commit message Signed-off-by:

Thomas Zimmermann authored
The simple pipe's disable function disables the screen by calling mgag200_disable_screen(). The simple pipe's enable function enables the screen by calling mgag200_enable_display(). During modeset operations the screen is off and remains off. It's only enabled after the modeset has been completed. Therefore remove all code that sets or clears the <scroff> field while in modeset. The related code also modifies the <syncrst> field in SEQ0. For now, keep this code in place. Signed-off-by:

The Documentation/DMA-API-HOWTO.txt states that the dma_map_sg() function returns the number of the created entries in the DMA address space. However the subsequent calls to the dma_sync_sg_for_{device,cpu}() and dma_unmap_sg must be called with the original number of the entries passed to the dma_map_sg(). struct sg_table is a common structure used for describing a non-contiguous memory buffer, used commonly in the DRM and graphics subsystems. It consists of a scatterlist with memory pages and DMA addresses (sgl entry), as well as the number of scatterlist entries: CPU pages (orig_nents entry) and DMA mapped pages (nents entry). It turned out that it was a common mistake to misuse nents and orig_nents entries, calling DMA-mapping functions with a wrong number of entries or ignoring the number of mapped entries returned by the dma_map_sg() function. To avoid such issues, lets use a common dma-mapping wrappers operating directly on the struct sg_table objects and use scatterlist page iterators where possible. This, almost always, hides references to the nents and orig_nents entries, making the code robust, easier to follow and copy/paste safe.

It doesn't hurt to add the bridge in the global bridge list also for platform specific dw-hdmi drivers which are based on the component framework. This can be achieved by moving the drm_bridge_add() function call from dw_hdmi_probe() to __dw_hdmi_probe(). A counterpart movement for drm_bridge_remove() is also needed then. Moreover, since drm_bridge_add() initializes &bridge->hpd_mutex, this may help those platform specific dw-hdmi drivers(based on the component framework) avoid accessing the uninitialized mutex in drm_bridge_hpd_notify() which is called in dw_hdmi_irq(). Putting drm_bridge_add() in __dw_hdmi_probe() just before it returns successfully should bring no logic change for platforms based on the DRM bridge API, which is a good choice from safety point of view. Also, __dw_hdmi_probe() is renamed to dw_hdmi_probe() since dw_hdmi_probe() does nothing else but calling __dw_hdmi_probe(). Similar renaming applies to the __dw_hdmi_remove()/dw_hdmi_remove() pair.
