2020-07-16drm/panel-simple: Fix inverted V/H SYNC for Frida FRD350H54004 panelPaul Cercueil
The FRD350H54004 panel was marked as having active-high VSYNC and HSYNC signals, which sorts-of worked, but resulted in the picture fading out under certain circumstances. Fix this issue by marking VSYNC and HSYNC signals active-low. v2: Rebase on drm-misc-next Fixes: 7b6bd8433609 ("drm/panel: simple: Add support for the Frida FRD350H54004 panel") Cc: stable@vger.kernel.org # v5.5 Signed-off-by: Paul Cercueil <paul@crapouillou.net> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200716125647.10964-1-paul@crapouillou.net

2020-07-10drm/panel: Replace HTTP links with HTTPS onesAlexander A. Klimov
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2020-06-29drm/panel: use mipi_dsi_dcs_write_buffer where possibleEmil Velikov
A few of the new panels create a local macro wrapping around mipi_dsi_dcs_write. At the same time, they don't really care about the command/payload split. mipi_dsi_dcs_write does a kmalloc/memcpy/kfree for payload > 7 bytes. Avoid that all together by using the _buffer function. Aside: panel-xinpeng-xpp055c272.c calls its wrapper "generic" although it should be "dcs". But that for another day/patch.

2020-06-20drm/panel-simple: Add missing connector type for some panelsDmitry Osipenko
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.

2020-05-27drm: Nuke mode->vrefreshVille Syrjälä
Get rid of mode->vrefresh and just calculate it on demand. Saves a bit of space and avoids the cached value getting out of sync with reality. 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 <a.hajda@samsung.com> Cc: Neil Armstrong <narmstrong@baylibre.com> Cc: Laurent Pinchart <Laurent.pinchart@ideasonboard.com> Cc: Jonas Karlman <jonas@kwiboo.se> Cc: Jernej Skrabec <jernej.skrabec@siol.net> Cc: Inki Dae <inki.dae@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Cc: Seung-Woo Kim <sw0312.kim@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: CK Hu <ck.hu@mediatek.com> Cc: Philipp Zabel <p.zabel@pengutronix.de> Cc: Ben Skeggs <bskeggs@redhat.com> Cc: Thierry Reding <thierry.reding@gmail.com> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Jerry Han <hanxu5@huaqin.corp-partner.google.com> Cc: Icenowy Zheng <icenowy@aosc.io> Cc: Jagan Teki <jagan@amarulasolutions.com> Cc: Stefan Mavrodiev <stefan@olimex.com> Cc: Robert Chiras <robert.chiras@nxp.com> Cc: "Guido Günther" <agx@sigxcpu.org> Cc: Purism Kernel Team <kernel@puri.sm> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: VMware Graphics <linux-graphics-maintainer@vmware.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Cc: linux-amlogic@lists.infradead.org Cc: nouveau@lists.freedesktop.org Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Reviewed-by: Sam Ravnborg <sam@ravnborg.org> Acked-by: Linus Walleij <linus.walleij@linaro.org> Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20200428171940.19552-4-ville.syrjala@linux.intel.com
2020-05-09drm/panel-simple: Support hpd-gpios for delaying prepare()Douglas Anderson
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 Anderson
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 Anderson
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 <dianders@chromium.org> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20200508155859.1.I4d29651c0837b4095fb4951253f44036a371732f@changeid
