2020-08-13drm/mcde: Enable the DSI link with displayLinus Walleij
The MCDE DSI link hardware which is modeled like a bridge in DRM, connected further to the panel bridge, creating a pipeline. We have been using the .pre_enable(), .enable(), .disable() and .post_disable() callbacks from the bridge to set this up in a chained manner: first the display controller goes online and then in successive order each bridge in the pipeline. Inside DRM it works like this: drm_atomic_helper_commit_tail() drm_atomic_helper_commit_modeset_enables() struct drm_crtc_helper_funcs .atomic_enable() struct drm_simple_display_pipe_funcs .enable() MCDE display enable call drm_atomic_bridge_chain_enable() struct drm_bridge_funcs .pre_enable() mcde_dsi_bridge_pre_enable() panel_bridge_pre_enable() struct drm_panel_funcs .prepare() struct drm_bridge_funcs .enable() mcde_dsi_bridge_enable() panel_bridge_enable() struct drm_panel_funcs .enable() A similar sequence is executed for disabling. Unfortunately this is not what the hardware needs: at a certain stage in the enablement of the display controller the DSI link needs to come up to support video mode, else something (like a FIFO flow) locks up the hardware and we never get picture. Fix this by simply leaving the pre|enable and post|disable callbacks unused, and establish two cross-calls from the display controller to bring up the DSI link at the right place in the display bring-up sequence and vice versa in the shutdown sequence. For command mode displays, it works just fine to also enable the display flow early. The only time we hold it back right now is in one-shot mode, on-demand display updates. When combined with the previous patch and some patches for the S6E63M0 display controller to support DSI mode, this gives working display on the Samsung GT-I8190 (Golden) phone. It has also been tested working on the Samsung GT-S7710 (Skomer) phone.

2020-08-13drm/mcde: Fix display pipeline restartLinus Walleij
To make sure that the MCDE is in a reasonable state during set-up, perform a reset by power cycling the block by dropping the on-chip regulator reference after probe. The display subsystem (DSS) has no dedicated reset line so dropping the EPOD regulator is the only real way of resetting it. We introduce code to enable and disable the regulator in the display enable/disable callbacks. We move the generic MCDE setup such as muxing of DPI signals and masking of interrupts to the display handling. When we drop the power to the whole display subsystem, not only MCDE but also the DSI links lose their state. Therefore we move the DSI block reset and hardware initialization code to the mcde_dsi_bridge_pre_enable() callback so this happens every time we start up the bridge, as we may have lost the power. We move the final disablement of the interrupts and clocks to the mcde_dsi_bridge_post_disable() callback rather than have it in the mcde_dsi_bridge_disable() callback, as some control messages may still be sent over the DSI host after the bridge has been shut down. This (together with a patch for the corresponding panel) makes the Samsung GT-S7710 successfully disable and re-enable its display, cutting all power while disabled and re-initializing the hardware when coming back up.

2020-08-13drm/mcde: Improve pixel fetcher FIFO depth settingLinus Walleij
The pixel fetcher FIFO depth was just hardcoded to 48 which works fine as long as the framebuffer is 32BPP and the DSI output is RGB888. We will need more elaborate handling for some buffer formats and displays, so start to improve this function by setting reasonable defaults for 32, 24 and 16 BPP framebuffers.

2020-08-13drm/mcde: Fix display data flow controlLinus Walleij
Revamp the way that the flow of data to the display is defined. I realized that the hardware supports something like 5 different modes of flow: oneshot, command with TE IRQ, command with BTA (bus turn around) and TE IRQ, video with TE IRQ and video without TE IRQ instead synchronizing to the output of the MCDE DSI formatter. Like before the selection of the type of flow is done from the DSI driver when we attach it to the MCDE and we get to know what the display wants. The new video mode synchronization method from the MCDE DSI formatter is used on some upstream devices such as Golden. This is the new default for video mode: stateless panels do not as a rule generate TE IRQs. Another semantic change is that we stop sending a TE request before every command when sending data to a display in command mode: this should only be explicitly requested when using BTA, according to the vendor driver. This has been tested and works fine with the command mode displays I have. (All that are supported upstream.)

2020-08-12drm/hisilicon: Code refactoring for hibmc_drv_deTian Tao
The memory used to be allocated with devres helpers and released automatically. In rare circumstances, the memory's release could have happened before the DRM device got released, which would have caused memory corruption of some kind. Now we're embedding the data structures in struct hibmc_drm_private. The whole release problem has been resolved, because struct hibmc_drm_private is allocated with drmm_kzalloc and always released with the DRM device.

2020-08-11drm/panel-notatek-nt35510: Fix MTP read initLinus Walleij
In order to successfully read ID of the MTP panel the panel MTP control page must be unlocked. Previously this wasn't encountered because in the setup with this panel the power wasn't ever really dropped. When power gets dropped from the panel, MTP needs to be unlocked.

2020-08-11drm: report dp downstream port type as a subconnector propertyOleg Vasilev
Currently, downstream port type is only reported in debugfs. This information should be considered important since it reflects the actual physical connector type. Some userspace (e.g. window compositors) may want to show this info to a user. The 'subconnector' property is already utilized for DVI-I and TV-out for reporting connector subtype. The initial motivation for this feature came from i2c test [1]. It is supposed to be skipped on VGA connectors, but it cannot detect VGA over DP and fails instead. v2: - Ville: utilized drm_dp_is_branch() - Ville: implement DP 1.0 downstream type info - Replaced create_dp_properties with add_dp_subconnector_property - Added dp_set_subconnector_property helper v4: - Ville: add DP1.0 best assumption about subconnector - Ville: assume DVI is DVI-D - Ville: reuse Writeback enum value for Virtual subconnector - Renamed #defines: HDMI -> HDMIA, DP -> DisplayPort v5: rebase v6: - Jani Nikula: renamed a function name - Jani Nikula: addressed the issues with documentation [1]: https://bugs.freedesktop.org/show_bug.cgi?id=104097 Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: intel-gfx@lists.freedesktop.org Signed-off-by: Jeevan B <jeevan.b@intel.com> Signed-off-by: Oleg Vasilev <oleg.vasilev@intel.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/1587732655-17544-1-git-send-email-jeevan.b@intel.com
