2019-06-10drm/omap: add support for manually updated displaysSebastian Reichel3-5/+129
This adds the required infrastructure for manually updated displays, such as DSI command mode panels. While those panels often support partial updates we currently always do a full refresh. The display will be refreshed when something calls the dirty callback, such as libdrm's drmModeDirtyFB(). This is currently being done at least by the kernel console and Xorg (with modesetting driver) in their default configuration. Weston does not implement this and the fbdev backend does not work (display will not update). Weston's DRM backend uses double buffering and the page flip will also trigger a display refresh.

drm_get_format_info directly calls into drm_format_info, but takes directly a struct drm_mode_fb_cmd2 pointer, instead of the fourcc directly. It's shorter to not dereference it, and we can customise the behaviour at the driver level if we want to, so let's switch to it where it makes sense.

2019-05-20drm: Remove users of drm_format_num_planesMaxime Ripard1-1/+3
drm_format_num_planes() is basically a lookup in the drm_format_info table plus an access to the num_planes field of the appropriate entry. Most drivers are using this function while having access to the entry already, which means that we will perform an unnecessary lookup. Removing the call to drm_format_num_planes is therefore more efficient. Some drivers will not have access to that entry in the function, but in this case the overhead is minimal (we just have to call drm_format_info() to perform the lookup) and we can even avoid multiple, inefficient lookups in some places that need multiple fields from the drm_format_info structure.

2019-03-27drm/omap: hdmi4_cec: Fix CEC clock handling for PMTony Lindgren1-7/+19
If CONFIG_OMAP4_DSS_HDMI_CEC is enabled in .config, deeper SoC idle states are blocked because the CEC clock gets always enabled on init. Let's fix the issue by moving the CEC clock handling to happen later in hdmi_cec_adap_enable() as suggested by Hans Verkuil <hverkuil@xs4all.nl>. This way the CEC clock gets only enabled when needed. This can be tested by doing cec-ctl --playback to enable the CEC, and doing cec-ctl --clear to disable it. Let's also fix the typo for "divider" in the comments while at it.

2019-03-18drm/omap: dsi: Fix PM for display blank with paired dss_pll callsTony Lindgren1-29/+31
Currently dsi_display_init_dsi() calls dss_pll_enable() but it is not paired with dss_pll_disable() in dsi_display_uninit_dsi(). This leaves the DSS clocks enabled when the display is blanked wasting about extra 5mW of power while idle. The clock that is left on by not calling dss_pll_disable() is DSS_CLKCTRL bit 10 OPTFCLKEN_SYS_CLK that is the source clock for DSI PLL. We can fix this issue by by making the current dsi_pll_uninit() into dsi_pll_disable(). This way we can just call dss_pll_disable() from dsi_display_uninit_dsi() and the code becomes a bit easier to follow. However, we need to also consider that DSI PLL can be muxed for DVI too as pointed out by Tomi Valkeinen <tomi.valkeinen@ti.com>. In the DVI case, we want to unconditionally disable the clocks. To get around this issue, we separate out the DSI lane handling from dsi_pll_enable() and dsi_pll_disable() as suggested by Tomi in an earlier experimental patch. So we must only toggle the DSI regulator based on the vdds_dsi_enabled flag from dsi_display_init_dsi() and dsi_display_uninit_dsi(). We need to make these two changes together to avoid breaking things for DVI when fixing the DSI clock handling. And this all causes a slight renumbering of the error path for dsi_display_init_dsi().

2019-03-18drm/omap: Whitelist DT nodes to fixup with omapdss, prefixLaurent Pinchart2-8/+33
The omapdss driver patches DT at runtime to prepend an "omapdss," prefix to the compatible string of all encoders, panels and connectors. This mechanism ensures they get bound to the omapdss-specific drivers instead of generic drivers. Now that we have drm_bridge support in omapdrm, we need to selectively disable this mechanism. Add a whitelist of compatible strings to patch, and fill it with all the devices we support. They will be removed one by one once corresponding drm_bridge drivers become available and get successfully tested with omapdrm. The omapdss components load check code is updated accordingly to ignore devices managed by external bridge drivers.

2019-03-18drm/omap: Add support for drm_bridgeLaurent Pinchart9-62/+145
Hook up drm_bridge support in the omapdrm driver. Despite the recent extensive preparation work, this is a rather intrusive change, as the management of outputs needs to be adapted through the driver to handle both omap_dss_device and drm_bridge. Connector creation is skipped when using a drm_bridge, as the bridge creates the connector internally. This creates issues with systems that split connector operations (such as modes retrieval and hot-plug detection) across different bridges. These systems can't be supported using drm_bridge for now (their support through the omap_dss_device infrastructure is not affected), this will be fixed in subsequent changes.

2019-03-18drm: Use new DRM_BUS_FLAG_*_(DRIVE|SAMPLE)_(POS|NEG)EDGE flagsLaurent Pinchart10-22/+29
The DRM_BUS_FLAG_PIXDATA_(POS|NEG)EDGE and DRM_BUS_FLAG_SYNC_(POS|NEG)EDGE flags are deprecated in favour of the new DRM_BUS_FLAG_PIXDATA_(DRIVE|SAMPLE)_(POS|NEG)EDGE and new DRM_BUS_FLAG_SYNC_(DRIVE|SAMPLE)_(POS|NEG)EDGE flags. Replace them through the code. This effectively changes the value of the .sampling_edge bridge timings field in the dumb-vga-dac driver. This is safe to do as no driver consumes these values yet.

2019-03-18drm/omap: Merge omap_dss_device type and output_type fieldsLaurent Pinchart25-20/+32
The omap_dss_device type and output_type fields differ mostly for historical reasons. The output_type field is required for all devices but the display at the end of the pipeline, and must be set to OMAP_DISPLAY_TYPE_NONE for the latter. The type field is required for all devices but the internal encoder, for which it is ignored. The only reason why the output_type field must be set to OMAP_DISPLAY_TYPE_NONE for the display at the end of the pipeline is to identify omap_dss_device instances corresponding to displays. This is not documented and confusing. Clean the code by adding a new display field to the omap_dss_device structure to identify displays, and merge the type and output_type fields.

2019-03-18drm/omap: Refactor initialization sequenceLaurent Pinchart1-67/+56
The omapdrm driver initialization procedure starts by connecting all available pipelines, gathering related information (such as output and display DSS devices, and DT aliases), sorting them by alias, and finally creates all the DRM/KMS objects. When using DRM bridges instead of DSS devices, we will need to attach to the bridges before getting the aliases. As attaching to bridges requires an encoder object, we have to reorganize the initialization sequence to create encoders before getting aliases and sorting the pipelines.

2019-03-18drm/omap: Pass drm_display_mode to .check_timings() and .set_timings()Laurent Pinchart9-48/+46
The omap_dss_device .check_timings() and .set_timings() operations operate on struct videomode, while the DRM API operates on struct drm_display_mode. This forces conversion from to videomode in the callers. While that's not a problem per se, it creates a difference with the drm_bridge API. Replace the videomode parameter to the .check_timings() and .set_timings() operations with a drm_display_mode. This pushed the conversion to videomode down to the DSS devices in some cases. If needed they will be converted to operate on drm_display_mode natively.

Display pipelines based on drm_bridge are handled from the bridge closest to the CRTC. To move to that model we thus need to transition away from walking pipelines in the other direction, and from accessing the device at the end of the pipeline when possible. Remove most accesses to the display device from the omap_connector implementation, and don't store it in the omap_connector structure. - For debug messages we can simply use the connector name instead. - For type checks we can use the drm_connector type. - For operation lookup we can start at the other end of the pipeline and locate the last matching device. The display device is still passed to the connector init function in order to find its type, which requires access to the end of the pipeline.
