The meson-dw-hdmi driver needs to access its own context from the .mode_valid() operation.

2020-06-23drm: bridge: dw-hdmi: Pass private data pointer to .mode_valid()Laurent Pinchart1-1/+2
Platform glue drivers for dw_hdmi may need to access device-specific data from their .mode_valid() implementation. They currently have no clean way to do so, and one driver hacks around it by accessing the dev_private data of the drm_device retrieved from the connector. Add a priv_data void pointer to the dw_hdmi_plat_data structure, and pass it to the .mode_valid() function.

2020-03-10drm/meson: Add YUV420 output supportNeil Armstrong1-21/+70
This patch adds support for the YUV420 output from the Amlogic Meson SoCs Video Processing Unit to the HDMI Controller. The YUV420 is obtained by generating a YUV444 pixel stream like the classic HDMI display modes, but then the Video Encoder output can be configured to down-sample the YUV444 pixel stream to a YUV420 stream. In addition if pixel stream down-sampling, the Y Cb Cr components must also be mapped differently to align with the HDMI2.0 specifications. This mode needs a different clock generation scheme since the TMDS PHY clock must match the 10x ratio with the YUV420 pixel clock, but the video encoder must run at 2x the pixel clock. This patch enables the bridge bus format negociation, and handles the YUV420 case if selected by the negociation.

2019-01-24drm: Split out drm_probe_helper.hDaniel Vetter1-2/+2
Having the probe helper stuff (which pretty much everyone needs) in the drm_crtc_helper.h file (which atomic drivers should never need) is confusing. Split them out. To make sure I actually achieved the goal here I went through all drivers. And indeed, all atomic drivers are now free of drm_crtc_helper.h includes. v2: Make it compile. There was so much compile fail on arm drivers that I figured I'll better not include any of the acks on v1. v3: Massive rebase because i915 has lost a lot of drmP.h includes, but not all: Through drm_crtc_helper.h > drm_modeset_helper.h -> drmP.h there was still one, which this patch largely removes. Which means rolling out lots more includes all over. This will also conflict with ongoing drmP.h cleanup by others I expect. v3: Rebase on top of atomic bochs. v4: Review from Laurent for bridge/rcar/omap/shmob/core bits: - (re)move some of the added includes, use the better include files in other places (all suggested from Laurent adopted unchanged). - sort alphabetically v5: Actually try to sort them, and while at it, sort all the ones I touch. v6: Rebase onto i915 changes. v7: Rebase once more.

2018-11-26drm/meson: Enable fast_io in meson_dw_hdmi_regmap_configLyude Paul1-0/+1
Seeing as we use this registermap in the context of our IRQ handlers, we need to be using spinlocks for reading/writing registers so that we can still read them from IRQ handlers without having to grab any mutexes and accidentally sleep. We don't currently do this, as pointed out by lockdep: [ 18.403770] BUG: sleeping function called from invalid context at kernel/locking/mutex.c:908 [ 18.406744] in_atomic(): 1, irqs_disabled(): 128, pid: 68, name: kworker/u17:0 [ 18.413864] INFO: lockdep is turned off.

2018-07-16drm/meson: Make DMT timings parameters and pixel clock genericNeil Armstrong1-8/+14
Remove the modes timings tables for DMT modes and calculate the HW paremeters from the modes timings. Switch the DMT modes pixel clock calculation out of the static frequency list to a generic calculation from a range of possible PLL dividers. This patch is an intermediate step towards usage of the Common Clock Framwework for PLL setup, by reworking the code to have common sel_pll() function called by the CEA (HDMI) freq setup and the generic DMT frequencies setup, we should be able to simply call clk_set_rate() on the PLL clock handle in a near future. The CEA (HDMI) and CVBS modes needs very specific clock paths that CCF will never be able to determine by itself, so there is still some work to do for a full handoff to CCF handling the clocks. This setup permits setting non-CEA modes like : - 1600x900-60Hz - 1280x1024-75Hz - 1280x1024-60Hz - 1440x900-60Hz - 1366x768-60Hz - 1280x800-60Hz - 1152x864-75Hz - 1024x768-75Hz - 1024x768-70Hz - 1024x768-60Hz - 832x624-75Hz - 800x600-75Hz - 800x600-72Hz - 800x600-60Hz - 640x480-75Hz - 640x480-73Hz - 640x480-67Hz Signed-off-by: Neil Armstrong <[email protected]> Acked-by: Jerome Brunet <[email protected]> [narmstrong: fixed trivial checkpatch issues] Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

This patch adds support for DMT display modes over HDMI. The modes timings configurations are from the Amlogic Vendor linux tree and tested over multiples monitors. Previously only a selected number of CEA modes were supported. Only these following modes are supported with these changes: - 640x480@60Hz - 800x600@60Hz - 1024x768@60Hz - 1152x864@75Hz - 1280x1024@60Hz - 1600x1200@60Hz - 1920x1080@60Hz The associated code to handle the clock rates is also added.

2018-02-16drm/bridge/synopsys: dw-hdmi: don't clobber drvdataJernej Skrabec1-4/+10
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.

2018-02-16drm/bridge/synopsys: dw-hdmi: Export some PHY related functionsJernej Skrabec1-4/+4
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.

Now that we have a callback to check if bridge supports a given mode we can use it in Synopsys Designware HDMI bridge so that we restrict the number of probbed modes to the ones we can actually display. Also, there is no need to use mode_fixup() callback as mode_valid() will handle the mode validation. NOTE: I also had to change the pdata declaration of mode_valid custom callback so that the passed modes are const. I also changed in the platforms I found. Not even compiled it though.
