2022-05-02drm/msm/dpu: Issue MDSS reset during initializationBjorn Andersson1-0/+32
It's typical for the bootloader to bring up the display for showing a boot splash or efi framebuffer. But in some cases the kernel driver ends up only partially configuring (in particular) the DPU, which might result in e.g. that two different data paths attempts to push data to the interface - with resulting graphical artifacts. Naturally the end goal would be to inherit the bootloader's configuration and provide the user with a glitch free handover from the boot configuration to a running DPU. But as implementing seamless transition from the bootloader configuration to the running OS will be a considerable effort, start by simply resetting the entire MDSS to its power-on state, to avoid the partial configuration.

2022-05-02drm/msm/dpu: Bind pingpong block to intf on active ctls in cmd encoderMarijn Suijten1-0/+19
As per the specification of DPU_CTL_ACTIVE_CFG the configuration of active blocks should be proactively specified, and the pingpong block is no different. The downstream display driver [1] confirms this by also calling bind_pingpong_blk on CTL_ACTIVE_CFG. Note that this else-if is always entered, as setup_intf_cfg - unlike this mainline dpu driver that combines both behind the same function pointer - is left NULL in favour of using setup_intf_cfg_v1 when CTL_ACTIVE_CFG is set. This solves continuous timeouts on at least the Qualcomm sm6125 SoC: [drm:dpu_encoder_frame_done_timeout:2091] [dpu error]enc31 frame done timeout [drm:_dpu_encoder_phys_cmd_handle_ppdone_timeout.isra.0] *ERROR* id:31 pp:0 kickoff timeout 0 cnt 1 koff_cnt 1 [drm:dpu_encoder_phys_cmd_prepare_for_kickoff] *ERROR* failed wait_for_idle: id:31 ret:-110 pp:0 In the same way this pingpong block should also be unbound followed by an interface flush when the encoder is disabled, according to the downstream display driver [2].

2022-04-29drm/bridge: tc358767: Fix (e)DP bridge endpoint parsing in dedicated functionMarek Vasut1-1/+1
Per toshiba,tc358767.yaml DT binding document, port@2 the output (e)DP port is optional. In case this port is not described in DT, the bridge driver operates in DPI-to-DP mode. The drm_of_find_panel_or_bridge() call in tc_probe_edp_bridge_endpoint() returns -ENODEV in case port@2 is not present in DT and this specific return value is incorrectly propagated outside of tc_probe_edp_bridge_endpoint() function. All other error values must be propagated and are propagated correctly. Return 0 in case the port@2 is missing instead, that reinstates the original behavior before the commit this patch fixes.

2022-04-29drm/display: Select DP helper for DRM_DP_AUX_CHARDEV and DRM_DP_CECJavier Martinez Canillas1-2/+4
The DRM_DP_AUX_CHARDEV and DRM_DP_CEC Kconfig symbols enable code that use DP helper functions, that are only present if CONFIG_DRM_DISPLAY_DP_HELPER is also enabled. But these don't select the DRM_DISPLAY_DP_HELPER symbol, meaning that it is possible to enable any of them without CONFIG_DRM_DISPLAY_DP_HELPER. That will lead to the following linking errors with the mentioned config: LD vmlinux.o MODPOST vmlinux.symvers MODINFO modules.builtin.modinfo GEN modules.builtin LD .tmp_vmlinux.kallsyms1 KSYMS .tmp_vmlinux.kallsyms1.S AS .tmp_vmlinux.kallsyms1.S LD .tmp_vmlinux.kallsyms2 KSYMS .tmp_vmlinux.kallsyms2.S AS .tmp_vmlinux.kallsyms2.S LD vmlinux SYSMAP System.map SORTTAB vmlinux OBJCOPY arch/arm64/boot/Image MODPOST modules-only.symvers ERROR: modpost: "drm_dp_dpcd_write" [drivers/gpu/drm/display/drm_display_helper.ko] undefined!
