2020-07-27drm/panel: panel-simple: validate panel descriptionSam Ravnborg1-2/+39
Warn if we detect a panel with incomplete/wrong description. This is inspired by a similar patch by Laurent that introduced checks for LVDS panels - this extends the checks to the remaining type of connectors. This is known to warn for some of the existing panels but added despite this as we need help from people using the panels to add the missing info. The checks are not complete but will catch the most common mistakes. The checks at the same time serve as documentation for the minimum required description for a panel. The checks uses dev_warn() as we know this will hit. WARN() was too noisy at the moment for anything else than LVDS. v3: - %d => %u for bpc (Laurent) v2: - Use dev_warn (Laurent) - Check for empty bus_flags Signed-off-by: Sam Ravnborg <[email protected]> Reviewed-by: Laurent Pinchart <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Sam Ravnborg <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]

2020-07-26drm: panel: simple: Delay HPD checking on boe_nv133fhm_n61 for 15 msDouglas Anderson1-1/+15
On boe_nv133fhm_n62 (and presumably on boe_nv133fhm_n61) a scope shows a small spike on the HPD line right when you power the panel on. The picture looks something like this: +-------------------------------------- | | | Power ---+ +--- | ++ | +----+| | HPD -----+ +---------------------------+ So right when power is applied there's a little bump in HPD and then there's small spike right before it goes low. The total time of the little bump plus the spike was measured on one panel as being 8 ms long. The total time for the HPD to go high on the same panel was 51.2 ms, though the datasheet only promises it is < 200 ms. When asked about this glitch, BOE indicated that it was expected and persisted until the TCON has been initialized. If this was a real hotpluggable DP panel then this wouldn't matter a whole lot. We'd debounce the HPD signal for a really long time and so the little blip wouldn't hurt. However, this is not a hotpluggable DP panel and the the debouncing logic isn't needed and just shows down the time needed to get the display working. This is why the code in panel_simple_prepare() doesn't do debouncing and just waits for HPD to go high once. Unfortunately if we get unlucky and happen to poll the HPD line right at the spike we can try talking to the panel before it's ready. Let's handle this situation by putting in a 15 ms prepare delay and decreasing the "hpd absent delay" by 15 ms. That means: * If you don't have HPD hooked up at all you've still got the hardcoded 200 ms delay. * If you've got HPD hooked up you will always wait at least 15 ms before checking HPD. The only case where this could be bad is if the panel is sharing a voltage rail with something else in the system and was already turned on long before the panel came up. In such a case we'll be delaying 15 ms for no reason, but it's not a huge delay and I don't see any other good solution to handle that case. Even though the delay was measured as 8 ms, 15 ms was chosen to give a bit of margin.

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.

Mostly done with cocci, with the following manual fixups: - Remove the now empty loop in drm_helper_probe_single_connector_modes() - Fix __MODE() macro in ch7006_mode.c - Fix DRM_MODE_ARG() macro in drm_modes.h - Remove leftover comment from samsung_s6d16d0_mode - Drop the TODO @@ @@ struct drm_display_mode { ... - int vrefresh; ... }; @@ identifier N; expression E; @@ struct drm_display_mode N = { - .vrefresh = E }; @@ identifier N; expression E; @@ struct drm_display_mode N[...] = { ..., { - .vrefresh = E } ,... }; @@ expression E; @@ { DRM_MODE(...), - .vrefresh = E, } @@ identifier M, R; @@ int drm_mode_vrefresh(const struct drm_display_mode *M) { ... - if (M->vrefresh > 0) - R = M->vrefresh; - else if (...) { ... } ... } @@ struct drm_display_mode *p; expression E; @@ ( - p->vrefresh = E; | - p->vrefresh + drm_mode_vrefresh(p) ) @@ struct drm_display_mode s; expression E; @@ ( - s.vrefresh = E; | - s.vrefresh + drm_mode_vrefresh(&s) ) @@ expression E; @@ - drm_mode_vrefresh(E) ? drm_mode_vrefresh(E) : drm_mode_vrefresh(E) + drm_mode_vrefresh(E) @find_substruct@ identifier X; identifier S; @@ struct X { ... struct drm_display_mode S; ... }; @@ identifier find_substruct.S; expression E; identifier I; @@ { .S = { - .vrefresh = E } } @@ identifier find_substruct.S; identifier find_substruct.X; expression E; identifier I; @@ struct X I[...] = { ..., .S = { - .vrefresh = E } ,... }; v2: Drop TODO v3: Rebase v4: Rebase Cc: Andrzej Hajda <[email protected]> Cc: Neil Armstrong <[email protected]> Cc: Laurent Pinchart <[email protected]> Cc: Jonas Karlman <[email protected]> Cc: Jernej Skrabec <[email protected]> Cc: Inki Dae <[email protected]> Cc: Joonyoung Shim <[email protected]> Cc: Seung-Woo Kim <[email protected]> Cc: Kyungmin Park <[email protected]> Cc: Linus Walleij <[email protected]> Cc: CK Hu <[email protected]> Cc: Philipp Zabel <[email protected]> Cc: Ben Skeggs <[email protected]> Cc: Thierry Reding <[email protected]> Cc: Sam Ravnborg <[email protected]> Cc: Jerry Han <[email protected]> Cc: Icenowy Zheng <[email protected]> Cc: Jagan Teki <[email protected]> Cc: Stefan Mavrodiev <[email protected]> Cc: Robert Chiras <[email protected]> Cc: "Guido Günther" <[email protected]> Cc: Purism Kernel Team <[email protected]> Cc: Benjamin Gaignard <[email protected]> Cc: Vincent Abriou <[email protected]> Cc: VMware Graphics <[email protected]> Cc: Thomas Hellstrom <[email protected]> Cc: [email protected] Cc: [email protected] Reviewed-by: Laurent Pinchart <[email protected]> Reviewed-by: Emil Velikov <[email protected]> Reviewed-by: Sam Ravnborg <[email protected]> Acked-by: Linus Walleij <[email protected]> Signed-off-by: Ville Syrjälä <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/[email protected]
2020-05-09drm/panel-simple: Support hpd-gpios for delaying prepare()Douglas Anderson1-0/+53
People use panel-simple when they have panels that are builtin to their device. In these cases the HPD (Hot Plug Detect) signal isn't really used for hotplugging devices but instead is used for power sequencing. Panel timing diagrams (especially for eDP panels) usually have the HPD signal in them and it acts as an indicator that the panel is ready for us to talk to it. Sometimes the HPD signal is hooked up to a normal GPIO on a system. In this case we need to poll it in the correct place to know that the panel is ready for us. In some system designs the right place for this is panel-simple. When adding this support, we'll account for the case that there might be a circular dependency between panel-simple and the provider of the GPIO. The case this was designed for was for the "ti-sn65dsi86" bridge chip. If HPD is hooked up to one of the GPIOs provided by the bridge chip then in our probe function we'll always get back -EPROBE_DEFER. Let's handle this by allowing this GPIO to show up late if we saw -EPROBE_DEFER during probe. NOTE: since the gpio_get_optional() is used, if the "hpd-gpios" isn't there our variable will just be NULL and we won't do anything in prepare().

2020-05-09panel: simple: Add BOE NV133FHM-N62Douglas Anderson1-0/+5
All info I could find about this panel show that it behaves the same as the BOE NV133FHM-N61. However, it definitely appears to be a unique panel because reading the EDID shows "NV133FHM-N62". We'll add a string match for the new panel but until we find something unique about it we'll just point at the N61's structures.

2020-05-09panel: simple: Fix size and bpp of BOE NV133FHM-N61Douglas Anderson1-3/+3
The BOE NV133FHM-N61 is documented in the original commit to be a 13.3" panel, but the size listed in our struct doesn't match. Specifically: math.sqrt(30.0 * 30.0 + 18.7 * 18.7) / 2.54 ==> 13.92 Searching around on the Internet shows that the size that was in the structure was the "Outline Size", not the "Display Area". Let's fix it. Also the Internet says that this panel supports 262K colors. That's 6bpp, not 8bpp. Fixes: b0c664cc80e8 ("panel: simple: Add BOE NV133FHM-N61") Signed-off-by: Douglas Anderson <[email protected]> Signed-off-by: Sam Ravnborg <[email protected]> Link: https://patchwork.freedesktop.org/patch/msgid/20200508155859.1.I4d29651c0837b4095fb4951253f44036a371732f@changeid
