3ec5c157 - drm: xlnx: zynqmp_dpsub: Add DP audio support

Wed, 23 Oct 2024 11:52:43 +0000

drm: xlnx: zynqmp_dpsub: Add DP audio supportAdd basic DisplayPort audio support.Support non-live audio playback from two PCMs (DMA channels), and thevolume control in the audio mixer.As older dtb files may not have the audio DMA channels defined, thedriver will just mark the audio support as disabled if the audio DMA ismissing, and will continue with only display support.Note: Reset doesn't seem to work (ZYNQMP_DISP_AUD_SOFT_RESET). If we doa reset, audio playback won't start again even if, afaics, we do set upall the necessary registers. So, at the moment, resetting the audioblock in dp_dai_hw_free() is commented out.Tested-by: Anatoliy Klymenko Reviewed-by: Vishal Sagar Signed-off-by: Tomi Valkeinen Link: https://patchwork.freedesktop.org/patch/msgid/20241023-xilinx-dp-audio-v4-3-5128881457be@ideasonboard.com List of files: /linux-6.15/drivers/gpu/drm/xlnx/Makefile

76c8eeb7 - drm: xlnx: zynqmp_dpsub: Move DRM/KMS initialization to separate file

drm: xlnx: zynqmp_dpsub: Move DRM/KMS initialization to separate fileStart preparation for using the DPSUB as a standalone DisplayPortencoder without a display controller by moving the DRM/KMSinitialization to a new zynqmp_kms.c file.

d76271d2 - drm: xlnx: DRM/KMS driver for Xilinx ZynqMP DisplayPort Subsystem

Sun, 08 Jul 2018 02:05:34 +0000

drm: xlnx: DRM/KMS driver for Xilinx ZynqMP DisplayPort SubsystemThe Xilinx ZynqMP SoC has a hardened display pipeline named DisplayPortSubsystem. It includes a buffer manager, a video pipeline renderer(blender), an audio mixer and a DisplayPort source controller(transmitter). The DMA engine the provide data to the buffer manager, aswell as the DisplayPort PHYs that drive the lanes, are external to thesubsystem and interfaced using the DMA engine and PHY APIs respectively.This driver supports the DisplayPort Subsystem and implements- Two planes, for graphics and video- One CRTC that supports alpha blending- One encoder for the DisplayPort transmitter- One connector for an external monitorIt currently doesn't support- Color keying- Test pattern generation- Audio- Live input from the Programmable Logic (FPGA)- Output to the Programmable Logic (FPGA)Signed-off-by: Hyun Kwon Signed-off-by: Laurent Pinchart List of files: /linux-6.15/drivers/gpu/drm/xlnx/Makefile
