* drm/msm/sde: add shared display supportRahul Sharma2019-01-09
| | | | | | | | | | | | | | | | | | | Add support to shared display for panel stacking and split screen application. The current DRM framework only allows one atomic commit for each display, this change will create virtual display pipelines based on the physical display pipeline, and each virtual display can support independent async atomic commit. With the change user mode application can setup and update display on each virtual display and share the same physical port. No mode switch is allowed on virtual display. When all virtual displays are powered off, the physical display will also power off.

* drm/msm/sde: support to control layer mixer usageRahul Sharma2018-12-17
| | | | | | | | | | | | | This change enables resource manager to select the number of layer mixers to be reserved for a particular usecase. Number of mixers used will be controlled by the request from user by setting a SDE_RM_TOPCTL_FORCE_MIXER_CFG property. if SDE_RM_TOPCTL_FORCE_MIXER_CFG is set then num_lm = 1 Change-Id: I94d37cfd1632e4b8d42235c2c155d9cf6cf25fc2 Signed-off-by: Rahul Sharma <rahsha@codeaurora.org>
* drm: msm: add skip_ddc support for hdmi displaySuprith Malligere Shankaregowda2018-07-15
| | | | | | | | | | | HDMI display on auto boards has disabled pluggable function and hardcoded 1080p mode for output. So ddc related function should also be skipped. Otherwise, some error messages are printed when accessing ddc.

* msm: sde: add early display handoff featureGuchun Chen2017-07-25
| | | | | | | | | | | | | | | | | | | | | | | When enabling animation/static splash in LK, drm/kms driver needs to involve handoff code to support smooth transition. In display driver's probe, it will do following items: 1. Check the status in LK for early splash. 2. Add data bus bandwidth voting in function sde_splash_init. 2. Handle SMMU mapping issue to avoid SMMU fault problem. 3. Bypass hardware reset to avoid glitch. And after user's space is up, when first commit's vblank comes, it will call functions to: 1. Tell LK to stop static/animation display and to exit. 2. Set early_domain_map_attr to 1 to enable stage 1 translation in iommu driver. 3. Check the property of commit.If it's for HDMI, release HDMI resource. If for DSI, release DSI resource. 4. Recycle the memory to be available to system. 5. Withdraw the bus bandwidth voting.

* drm/msm/sde: remove display managerClarence Ip2016-11-02

* drm/msm/sde: add virtual writeback device and connectorAlan Kwong2016-08-08
| | | | | | | | | | | | | Enable virtual writeback connector by allowing a property on the connector to specify output frame buffer id, which takes in a framebuffer object added via ADDFB2 ioctl.

* dt-bindings: consolidate display related bindingsRob Herring2015-10-22
| | | | | | | | | | | | | | This is a quite large renaming to consolidate display related bindings into a single "display" directory from various scattered locations of video, drm, gpu, fb, mipi, and panel. The prior location was somewhat based on the Linux driver location, but bindings should be independent of that.

* drm/msm: dsi host: Use device graph parsing to parse connected panelArchit Taneja2015-08-15
| | | | | | | | | | | | | | | | | | | | | | | | | The dsi host looks for the connected panel node by parsing for a child named 'panel'. This hierarchy isn't very flexible. The connected panel is forced to be a child to the dsi host, and hence, a mipi dsi device. This isn't suitable for dsi devices that don't use mipi dsi as their control bus. Follow the of_graph approach of creating ports and endpoints to represent the connections between the dsi host and the panel connected to it. In our case, the dsi host will only have one output port, linked to the panel's input port. Update DT binding documentation with device graph usage info. v3: - Fix return value checks of of_graph_* calls. - Don't make port a mandatory DT property - Fix defer check when no panel node specified - Rename parse_dt func to align with other dsi_host funcs Reviewed-by: Hai Li <hali@codeaurora.org> Signed-off-by: Archit Taneja <architt@codeaurora.org> Signed-off-by: Rob Clark <robdclark@gmail.com>

Signed-off-by: Stephane Viau <sviau@codeaurora.org> [rename compatible s/8x94/8994/ since preference is to not trust the marketing folks who invent chip #'s but instead name things after the lead chip.. we should rename some 80XY to 89XY to standardize on the lead chip but leave that for another patch.

* drm/msm/dsi: Separate PHY to another platform deviceHai Li2015-06-11
| | | | | | | | | | | | There are different types of PHY from one chipset to another, while the DSI host controller is relatively consistent across platforms. Also, the PLL inside PHY is providing the source of DSI byte and pixel clocks, which are used by DSI host controller. Separated devices for clock provider and clock consumer make DSI driver better fit into common clock framework.
