The KR070PE2T is a 7" panel with a resolution of 800x480. KR070PE2T is the marking present on the ribbon cable.

2020-03-10drm/panel-simple: Fix dotclock for Ortustech COM37H3MH. Nikolaus Schaller
The currently listed dotclock disagrees with the currently listed vrefresh rate. Change the dotclock to match the vrefresh. There are two variants of the COM37H3M panel. The older one's COM37H3M05DTC data sheet specifies: MIN TYP MAX CLK frequency fCLK -- 22.4 26.3 MHz (in VGA mode) VSYNC Frequency fVSYNC 54 60 66 Hz VSYNC cycle time tv -- 650 -- H HSYNC frequency fHSYNC -- 39.3 -- kHz HSYNC cycle time th -- 570 -- CLK The newer one's COM37H3M99DTC data sheet says: MIN TYP MAX CLK frequency fCLK 18 19.8 27 MHz VSYNC Frequency fVSYNC 54 60 66 Hz VSYNC cycle time tv 646 650 700 H HSYNC frequency fHSYNC -- 39.0 50.0 kHz HSYNC cycle time th 504 508 630 CLK So we choose a parameter set that lies within the specs of both variants. We start at .vrefresh = 60, choose .htotal = 570 and .vtotal = 650 and end up in a clock of 22.230 MHz. Reported-by: Ville Syrjala <ville.syrjala@linux.intel.com> Signed-off-by: H.

2020-02-29drm/panel: simple: add panel-dpi supportSam Ravnborg
The panel-dpi compatible is a fallback that allows the DT to specify the timing. When matching panel-dpi expect the device tree to include the timing information for the display-panel. Background for this change: There are a lot of panels and new models hits the market very often. It is a lost cause trying to chase them all and users of new panels will often find them in situations that the panel they ues are not supported by the kernel. On top of this a lot of panels are customized based on customer specifications. Including the panel timing in the device tree allows for a simple way to describe the actual HW and use this description in a generic way in the kernel. This allows uses of proprietary panels, or panels which are not included in the kernel, to specify the timing in the device tree together with all the other HW descriptions. And thus, using the device tree it is then easy to add support for an otherwise unknown panel. The current support expect panels that do not require any delays for prepare/enable/disable/unprepare. Oleksandr Suvorov replied: I've just tested this patch on Apalis iMX6Q and Colibri iMX7D using panel settings from the following patch: https://lore.kernel.org/linux-arm-kernel/20200115123401.2264293-4-oleksandr.suvorov@toradex.com/ It works for me, thanks!

2020-01-12drm: panel: fix excessive stack usage in td028ttec1_prepareArnd Bergmann
With gcc -O3 in combination with the structleak plug, the compiler can inline very aggressively, leading to rather large stack usage: drivers/gpu/drm/panel/panel-tpo-td028ttec1.c: In function 'td028ttec1_prepare': drivers/gpu/drm/panel/panel-tpo-td028ttec1.c:233:1: error: the frame size of 2768 bytes is larger than 2048 bytes [-Werror=frame-larger-than=] } Marking jbt_reg_write_*() as noinline avoids the case where multiple instances of this function get inlined into the same stack frame and each one adds a copy of 'tx_buf'. The compiler is clearly making some bad decisions here, but I did not open a new bug report as this only happens in combination with the structleak plugin. This fixes mmtom ("init/Kconfig: enable -O3 for all arches") Link: https://lore.kernel.org/lkml/CAK8P3a3jAnFZA3GFRtdYdg1-i-oih3pOQzkkrK-X3BGsFrMiZQ@mail.gmail.com/ Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> [fix indent] Link: https://patchwork.freedesktop.org/patch/msgid/20200108135116.3687988-1-arnd@arndb.de

The Sony ACX424AKP is a command/videomode DSI panel for mobile devices. It is used on the ST-Ericsson HREF520 reference design. We support video mode by default, but it is possible to switch the panel into command mode by using the bool property "dsi-command-mode".
