The Versatile Express has 8 MB of dedicated video RAM (VRAM) on the motherboard, which is what we should be using for the PL111 if available. On this platform, the memory backplane is constructed so that only this memory will work properly with the CLCD on the motherboard, using any other memory area just gives random snow on the display. The CA9 Versatile Express also has a PL111 instance on its core tile that can address all memory, and this does not have the restriction. The memory is assigned to the device using the memory-region device tree property and a "shared-dma-pool" reserved memory pool like this: reserved-memory { #address-cells = <1>; #size-cells = <1>; ranges; vram: vram@48000000 { compatible = "shared-dma-pool"; reg = <0x48000000 0x00800000>; no-map; }; }; clcd@1f000 { compatible = "arm,pl111", "arm,primecell"; (...) memory-region = <&vram>; }·; Cc: Liviu Dudau <liviu.dudau@arm.com> Cc: Mali DP Maintainers <malidp@foss.arm.com> Reviewed-by:Eric Anholt <eric@anholt.net> Tested-by:

The Versatile Express uses a special configuration controller deeply embedded in the system motherboard FPGA to multiplex the two to three (!) display controller instances out to the single SiI9022 bridge. Set up an extra file with the logic to probe to the FPGA mux register on the system controller bus, then parse the device tree to see if there is a CLCD or HDLCD instance on the core tile (also known as the daughterboard) by looking in the root of the device tree for compatible nodes. - If there is a HDLCD on the core tile, and there is a driver for it, we exit probe and deactivate the motherboard CLCD. We do not touch the DVI mux in this case, to make sure we don't break HDLCD. - If there is a CLCD on both the motherboard and the core tile (only the CA9 has this) the core tile CLCD takes precedence and get muxed to the DVI connector. - Only if there is no working graphics on the core tile, the motherboard CLCD is probed and muxed to the DVI connector. Core tile graphics should always take precedence as it can address all memory and is also faster, however the motherboard CLCD is good to have around for diagnostics and testing. It is possible to test the motherboard CLCD by setting the status = "disabled" property on the core tile CLCD or HDLCD. Scale down the Versatile Express to 16BPP so we can support a 1024x768 display despite the bus bandwidth restrictions on this platform. (The motherboard CLCD supports slightly lower resolution.)

Blending win0 with the background color doesn't seem to work correctly. We only get the background color, no matter the contents of the win0 framebuffer. However, blending pre-multiplied color with the default opaque black default background color is a no-op, so we can just disable blending to get the correct result. Signed-off-by:

It turns out that I had just mistaken what type of write the register writes were supposed to be, using DCS instead of generic long writes. Switching to transactions instead of using the atmel as a bridge also seems to resolve the sparkling pixels problem I've had. Signed-off-by:

The PiTFT (ili9340) has a hardware reset circuit that resets only on power-on and not on each reboot through a gpio like the rpi-display does. As a result, we need to always apply the rotation value regardless of the display "on/off" state. Moved the rotation setting code below out_enable:. Signed-off-by:

No functional changes in this patch. The SDP Header is a generic header for secondary data packets for both eDP and DP so call it dp_sdp_header. This header gets used for different SDP types already defined. Also header bytes 2 and 3 are secondary data packet specific header bytes. So change the comment to indicate the same.

Add mode_valid() function to filter modes according to available pll clock values and "preferred" modes. It is particularly useful for hdmi modes that require precise pixel clocks. Note that "preferred" modes are always accepted: - this is important for panels because panel clock tolerances are bigger than hdmi ones and there is no reason to not accept them (the fps may vary a little but it is not a problem). - the hdmi preferred mode will be accepted too, but userland will be able to use others hdmi "valid" modes if necessary.

When a driver related to one of the endpoints is deferred due to probe dependencies (i2c, spi...) but the other one is ready, ltdc probe continues and the deferred driver will never be probed again. The fix consists in waiting for all deferred endpoints before continuing the ltdc probe. Signed-off-by:

The encoder callbacks are only called in case the video mode changes. So any layout changes without mode changes will go unnoticed. Add qxl_crtc_update_monitors_config(), based on the old qxl_write_monitors_config_for_encoder() function. Hook it into the enable, disable and flush atomic crtc callbacks. Remove monitors_config updates from all other places. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1544322Signed-off-by:

The "adjusted_mode" clock value (ie the real pixel clock) is more accurate than "mode" clock value (ie the panel/bridge requested clock value). It offers a better preciseness for timing computations and allows to reduce the extra dsi bandwidth in burst mode (from ~20% to ~10-12%, hw platform dependent). Signed-off-by:
