2020-08-18drm/panel: Use dev_ based loggingSam Ravnborg
Standardize on the dev_ based logging and drop the include of drm_print.h. Fix a few cases where "x@" was used when printing the mode.

2020-08-02drm/panel: remove return value of function drm_panel_addBernard Zhao
The function "int drm_panel_add(struct drm_panel *panel)" always returns 0, this return value is meaningless. Also, there is no need to check return value which calls "drm_panel_add and", error branch code will never run.

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
2019-12-13drm/panel: Add Boe Himax8279d MIPI-DSI LCD panelJerry Han
Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel. V11: - Use the backlight support in drm_panel to simplify the driver (Sam) V10: - Adjust init code, make the format more concise (Emil) V9: - kill off default_off_cmds (Emil) - use mipi_dsi_dcs_set_display_{on,off} in their enable/disable callbacks. (Emil) - Adjusting the delay function (Emil) V8: - modify PARENTHESIS_ALIGNMENT format (Sam) - use gpios are required API replace optional gpio API (Emil) V7: - Modify communication address V6: - Add the information of the reviewer - Remove unnecessary delays, The udelay_range code gracefully returns without hitting the scheduler on a delay of 0. (Derek) - Merge the same data structures, like display_mode and off_cmds (Derek) - Optimize the processing of results returned by devm_gpiod_get_optional (Derek) V5: - Add the information of the reviewer (Sam) - Delete unnecessary header files #include <linux/fb.h> (Sam) - The config DRM_PANEL_BOE_HIMAX8279D appears twice. Drop one of them (Sam) - ADD static, set_gpios function is not used outside this module (Sam) V4: - Frefix all function maes with boe_ (Sam) - Fsed "enable_gpio" replace "reset_gpio", Make it look clearer (Sam) - Sort include lines alphabetically (Sam) - Fixed entries in the makefile must be sorted alphabetically (Sam) - Add send_mipi_cmds function to avoid duplicating the code (Sam) - Add the necessary delay(reset_delay_t5) between reset and sending the initialization command (Rock wang) V3: - Remove unnecessary delays in sending initialization commands (Jitao Shi) V2: - Use SPDX identifier (Sam) - Use necessary header files replace drmP.h (Sam) - Delete unnecessary header files #include <linux/err.h> (Sam) - Specifies a GPIOs array to control the reset timing, instead of reading "dsi-reset-sequence" data from DTS (Sam) - Delete backlight_disable() function when already disabled (Sam) - Use devm_of_find_backlight() replace of_find_backlight_by_node() (Sam) - Move the necessary data in the DTS to the current file, like porch, display_mode and Init code etc. (Sam) - Add compatible device "boe,himax8279d10p" (Sam) V1: - Support Boe Himax8279d 8.0" 1200x1920 TFT LCD panel, it is a MIPI DSI panel.
