2020-06-26drm/debug: Expose connector VRR monitor range via debugfsBhanuprakash Modem1-0/+22
[Why] It's useful to know the min and max vrr range for IGT testing. [How] Expose the min and max vfreq for the connector via a debugfs file on the connector, "vrr_range". Example usage: cat /sys/kernel/debug/dri/0/DP-1/vrr_range v2: * Fix the typo in max_vfreq (Manasi) * Change the name of node to i915_vrr_info so we can add other vrr info for more debug info (Manasi) * Change the VRR capable to display Yes or No (Manasi) * Fix indentation checkpatch errors (Manasi) v3: * Remove the unnecessary debug print (Manasi) v4: * Rebase v5: * Rename to vrr_range to match AMD debugfs v6: * Rebase (manasi) v7: * Fix cmpilation due to rebase v8: * Move debugfs node creation logic to DRM (Emil) * Remove AMD specific logic (Emil) v9: * Separate patch for removal of AMD specific logic (Manasi) Signed-off-by: Bhanuprakash Modem <bhanuprakash.modem@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Cc: Jani Nikula <jani.nikula@linux.intel.com> Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Cc: Harry Wentland <harry.wentland@amd.com> CC: Emil Velikov <emil.l.velikov@gmail.com> Reviewed-by: Manasi Navare <manasi.d.navare@intel.com> Signed-off-by: Manasi Navare <manasi.d.navare@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200622142519.16214-3-bhanuprakash.modem@intel.com

2020-06-24drm/mipi-dbi: Remove ->enabledDaniel Vetter4-32/+12
The atomic helpers try really hard to not lose track of things, duplicating enabled tracking in the driver is at best confusing. Double-enabling or disabling is a bug in atomic helpers. In the fb_dirty function we can just assume that the fb always exists, simple display pipe helpers guarantee that the crtc is only enabled together with the output, so we always have a primary plane around. Now in the update function we need to be a notch more careful, since that can also get called when the crtc is off. And we don't want to upload frames when that's the case, so filter that out too.

2020-06-23drm: bridge: Pass drm_display_info to drm_bridge_funcs .mode_valid()Laurent Pinchart21-3/+28
When validating a mode, bridges may need to do so in the context of a display, as specified by drm_display_info. An example is the meson dw-hdmi bridge that needs to consider the YUV 4:2:0 output format to perform clock calculations. Bridges that need the display info currently retrieve it from the drm_connector created by the bridge. This gets in the way of moving connector creation out of bridge drivers. To make this possible, pass the drm_display_info to drm_bridge_funcs .mode_valid(). Changes to the bridge drivers have been performed with the following coccinelle semantic patch and have been compile-tested. @ rule1 @ identifier funcs; identifier fn; @@ struct drm_bridge_funcs funcs = { ..., .mode_valid = fn }; @ depends on rule1 @ identifier rule1.fn; identifier bridge; identifier mode; @@ enum drm_mode_status fn( struct drm_bridge *bridge, + const struct drm_display_info *info, const struct drm_display_mode *mode ) { ... } Signed-off-by: Laurent Pinchart <laurent.pinchart+renesas@ideasonboard.com> Reviewed-by: Neil Armstrong <narmstrong@baylibre.com> Reviewed-by: Boris Brezillon <boris.brezillon@collabora.com> Reviewed-by: Guido Günther <agx@sigxcpu.org> # for the nwl-dsi part: Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200526011505.31884-11-laurent.pinchart+renesas@ideasonboard.com

2020-06-23drm: bridge: adv7511: Implement bridge connector operationsLaurent Pinchart1-4/+39
Implement the bridge connector-related .get_edid(), .detect() and .hpd_notify() operations, and report the related bridge capabilities. Output status detection is implemented using the same backend as for the DRM connector, but requires making mode retrieval at detection time optional as no pointer to the connector is available to the bridge .detect() operation. The reason for the need to retrieve modes at detection time is unclear to me, and this may benefit from further refactoring of hot plug handling code. Hot plug detection is notified through the bridge HPD notification framework when the bridge is used without creating a connector, and falls back to the existing implementation otherwise. CEC handling of disconnection is handled in the new .hpd_notify() operation in the new code path.

The ast driver contains code paths for AST 1180 chips. The chip is not supported and the rsp code has never been tested. Simplify the driver by removing the AST 1180 code.

2020-06-20drm/bridge: tfp410: fix de-skew value retrieval from DTRicardo Cañuelo1-5/+5
The tfp410 has a data de-skew feature that allows the user to compensate the skew between IDCK and the pixel data and control signals. In the driver, the setup and hold times are calculated from the de-skew value. This retrieves the deskew value from the DT using the proper datatype and range check as described by the binding (u32 from 0 to 7). This fix results from a change in the ti,tfp410 DT binding.

This changes how the 'ti,deskew' property is defined. It's now an unsigned value from 0 to 7 instead of a signed value from -4 to 3. Until the dtc carries the integer sign through to the yaml output it's easier to define signed types as unsigned.

2020-06-20drm/panel-simple: Add missing connector type for some panelsDmitry Osipenko1-0/+7
The DRM panel bridge core requires connector type to be set up properly, otherwise it rejects the panel. The missing connector type problem popped up while I was trying to wrap CLAA070WP03XG panel into a DRM bridge in order to test whether panel's rotation property work properly using panel-simple driver on NVIDIA Tegra30 Nexus 7 tablet device, which uses CLAA070WP03XG display panel. The NVIDIA Tegra DRM driver recently gained DRM bridges support for the RGB output and now driver wraps directly-connected panels into DRM bridge. Hence all panels should have connector type set properly now, otherwise the panel's wrapping fails. This patch adds missing connector types for the LVDS panels that are found on NVIDIA Tegra devices: 1. AUO B101AW03 2. Chunghwa CLAA070WP03XG 3. Chunghwa CLAA101WA01A 4. Chunghwa CLAA101WB01 5.
