Some TCONs on newer SoCs doesn't support channel 0, since they are meant to be used only with TV or HDMI encoder. Prepare support for them with adding has_channel_0 quirk. Acked-by:

This commit adds all necessary compatibles and descriptions needed to implement A83T HDMI pipeline. Mixer is already properly described, so only compatible is added. However, A83T TV TCON, which is connected to HDMI, doesn't have channel 0, contrary to all TCONs currently described. Because of that, TCON documentation is extended. A83T features Synopsys DW HDMI controller with a custom PHY which looks like Synopsys Gen2 PHY with few additions. Since there is no documentation, needed properties were found out through experimentation and reading BSP code. At the end, example is added for newer SoCs, which feature DE2 and DW HDMI.

dw_hdmi shouldn't set drvdata since some drivers might need to store it's own data there. Rework dw_hdmi in a way to return struct dw_hdmi instead to store it in drvdata. This way drivers are responsible to store and pass structure when needed. Idea was taken from the following commit: 8242ecbd ("drm/bridge/synopsys: stop clobbering drvdata") Cc: p.zabel@pengutronix.de Cc: Laurent.pinchart@ideasonboard.com Cc: hjc@rock-chips.com Acked-by:

Parts of PHY code could be useful also for custom PHYs. For example, Allwinner A83T has custom PHY which is probably Synopsys gen2 PHY with few additional memory mapped registers, so most of the Synopsys PHY related code could be reused. Functions exported here are actually not specific to Synopsys PHYs but to DWC HDMI controller PHY interface. This means that even if the PHY is completely custom, i.e. not designed by Synopsys, exported functions can be useful. Reviewed-by:

The V3D engine has various hardware counters which might be interesting to userspace performance analysis tools. Expose new ioctls to create/destroy a performance monitor object and query the counter values of this perfmance monitor. Note that a perfomance monitor is given an ID that is only valid on the file descriptor it has been allocated from. A performance monitor can be attached to a CL submission and the driver will enable HW counters for this request and update the performance monitor values at the end of the job. Signed-off-by:

ltdc supports natively some color formats with alpha (like ARGB8888, ARGB1555, ARGB4444...). Related non-alpha formats are supported too (ARGB8888->XRGB8888, ARGB4444->XRGB4444...) by adjusting ltdc blending factors.

The Versatile PL110 implementations use multiple endpoints: from the PL111 port, the lines are routed through a PLD, and from there forked so the same lines go to a VGA DAC and an external TFT panel connector. This is discrete wireing so there is no way to turn of one output, i.e. this is really two endpoints, not two ports. We model this with multiple endpoints, so we need to loop over the available endpoints, check for panel or bridge on each and accumulate the result before continuing. The code already will give the panel preference over the bridge, if present, so the output will be sent to the panel if both a panel and a bridge is present on two endpoints of the same port. If they all return -EPROBE_DEFER we return -EPROBE_DEFER as well. If just one endpoint is present on the port, the behaviour is the same as before. Reviewed-by:

The ARM Versatile series can do RGB/BGR565 with an external "PLD" (Programmable Logical Device). However the CLCD does not have control bits for this, so it needs to be set into the ordinary 16BPP mode, then the RGB/BGR565 handling of the pixel data is handled by configuring the PLD through the external register.

With a bit of refactoring we can contain the variant data for the strange PL110 versions that is feature-incomplete PL110 for the ARM Integrator/CP and somewhere inbetween PL110 and PL111 for the ARM Versatile AB and Versatile PB. We also accomodate for the custom duct-taped RGB565/BGR565 support in the Versatile variant. Reviewed-by:

The ARM reference designs "Versatile AB" and "Versatile PB" contain panel connectors with autodetection of the connected panel type. This adds a small driver utilizing the MFD syscon look-up to read the autodetection register and set up the corresponding panel appropriately. In the source file there is a bit of elaboration of the panel types and interfaces on these boards. This was tested with the PL111 DRM driver on the ARM Versatile AB with the IB2 daughterboard.

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. Note that this replaces crtc_state->adjusted_mode usage with crtc_state->mode. The latter is the correct choice since that's the mode the user provided and it matches the plane crtc coordinates the user also provided. Once everyone agrees on this we can move the clip handling into drm_atomic_helper_check_plane_state(). Cc: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by:

Use drm_mode_get_hv_timing() to fill out the plane clip rectangle. No functional changes as the code already uses crtc_state->mode to populate the clip, which is also what drm_mode_get_hv_timing() uses.

drm_encoder_slave is the old way to write bridge drivers, for i2c bridges only. It's deprecated, and definitely should not be used in new drivers. This has absolutely nothing to do with the new bridge driver infrastructure implemented by drm_bridge. What's even strange is that arcpgu doesn't even use any of this, it really only wants a plain normal drm_encoder. Nuke all the surplus real estate. v2: Actually git add after compile testing ... v3: Clarify commit message and stop including drm_encoder_slave.h.
