The goal of this series is to get the built-in LCD of the LEGO MINDSTORMS EV3 working. But, most of the content here is building up the infrastructure to do that.
The controller used in the EV3 uses MIPI commands, but it uses a different memory layout. The current tinydrm stuff is hard-coded for RGB565, so most of the patches are adding support for other memory layouts. I've also made the one existing tinydrm driver generic so that it can work for any MIPI display rather than copying a bunch of boiler-plate code for each panel and/or controller. Once all of this is done, it is really easy to add a new panel. :-) David Lechner (6): drm/tinydrm: Add parameter for MIPI DCS pixel format drm/tinydrm: add helpers for ST7586 controllers drm/tinydrm: rename mi028qt module to mipi-panel drm/tinydrm: mipi-panel: refactor to use driver id drm/tinydrm: add support for LEGO MINDSTORMS EV3 LCD ARM: dts: da850-lego-ev3: Add node for LCD display .../devicetree/bindings/display/mipi-panel.txt | 27 ++ .../bindings/display/multi-inno,mi0283qt.txt | 27 -- MAINTAINERS | 6 +- arch/arm/boot/dts/da850-lego-ev3.dts | 24 ++ drivers/gpu/drm/tinydrm/Kconfig | 13 +- drivers/gpu/drm/tinydrm/Makefile | 2 +- drivers/gpu/drm/tinydrm/core/tinydrm-helpers.c | 148 ++++++++ drivers/gpu/drm/tinydrm/mi0283qt.c | 282 --------------- drivers/gpu/drm/tinydrm/mipi-dbi.c | 117 ++++-- drivers/gpu/drm/tinydrm/mipi-panel.c | 395 +++++++++++++++++++++ include/drm/tinydrm/mipi-dbi.h | 9 +- include/drm/tinydrm/st7586.h | 34 ++ include/drm/tinydrm/tinydrm-helpers.h | 6 + include/video/mipi_display.h | 16 +- 14 files changed, 759 insertions(+), 347 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/mipi-panel.txt delete mode 100644 Documentation/devicetree/bindings/display/multi-inno,mi0283qt.txt delete mode 100644 drivers/gpu/drm/tinydrm/mi0283qt.c create mode 100644 drivers/gpu/drm/tinydrm/mipi-panel.c create mode 100644 include/drm/tinydrm/st7586.h -- 2.7.4
