Hi, This patch series aims to add Freescale i.MX8qxp Display Controller support.
The controller is comprised of three main components that include a blit engine for 2D graphics accelerations, display controller for display output processing, as well as a command sequencer. Previous patch series attempts to do that can be found at: https://patchwork.freedesktop.org/series/84524/ This series addresses Maxime's comments on the previous one: a. Split the display controller into multiple internal devices. 1) List display engine, pixel engine, interrupt controller and more as the controller's child devices. 2) List display engine and pixel engine's processing units as their child devices. b. Add minimal feature support. Only support two display pipelines with primary planes with XR24 fb, backed by two fetchunits. No fetchunit dynamic allocation logic(to be done when necessary). c. Use drm_dev_{enter, exit}(). Since this series changes a lot comparing to the previous one, I choose to send it with a new patch series, not a new version. To follow up i.MX8qxp TRM, I changed the controller name to "Display Controller" instead of the previous "DPU". "DPU" is only mentioned in the SoC block diagram and represents the whole display subsystem which includes the display controller and prefech engines, etc. With an additional patch[1] for simple-pm-bus.c, this series facilitates testing a LVDS panel on i.MX8qxp MEK. Please do NOT merge patch 14-19. [1] https://lkml.org/lkml/2023/1/25/120 v3: * Collect Rob's R-b tag on the patch for adding fsl,imx8qxp-dc-intc.yaml. * Combine fsl,imx8qxp-dc-fetchunit-common.yaml, fsl,imx8qxp-dc-fetchlayer.yaml and fsl,imx8qxp-dc-fetchwarp.yaml into 1 schema doc fsl,imx8qxp-dc-fetchunit.yaml. (Rob) * Document all processing units, command sequencer, axi performance counter and blit engine. (Rob) v2: * Drop fsl,dc-*-id DT properties from fsl,imx8qxp-dc*.yaml. (Krzysztof) * Move port property from fsl,imx8qxp-dc-display-engine.yaml to fsl,imx8qxp-dc-tcon.yaml. (Krzysztof) * Drop unneeded "|" from fsl,imx8qxp-dc-intc.yaml. (Krzysztof) * Use generic pmu pattern property in fsl,imx8qxp-dc.yaml. (Krzysztof) * Fix register range size in fsl,imx8qxp-dc*.yaml. * Use OF alias id to get instance id from display driver. * Find next bridge from TCon's port from display driver. * Drop drm/drm_module.h include from dc-drv.c. * Improve file list in MAINTAINERS. (Frank) * Add entire i.MX8qxp display controller device tree for review. (Krzysztof) * Add MIPI/LVDS subsystems device tree and a DT overlay for imx8qxp MEK to test a LVDS panel as an example.
