The STM32F429-DISCO has the LCD-TFT display controller connected to a parallel panel with MIPI-DBI over SPI for panel control. The LTDC driver was originally written for the STM32MP1, but had some issues last time I tested it a few years ago. I debugged it into submission on the STM32F429 now though, so it might just work on the MP1 as well. v2 -> v3: - fix copy-paste left-over v1 -> v2: - removed stray Kconfig hunk for panel support to appropriate patch (Sascha) - fixed Kconfig help text for mipi_dbi helper Ahmad Fatoum (4): gpiolib: implement gpiod_set_value video: add driver for STM32 LCD-TFT Display Controller video: add MIPI DBI Type C Option 3 support video: add Ilitek ILI9341 panel support commands/Kconfig | 15 + commands/Makefile | 1 + drivers/video/Kconfig | 22 ++ drivers/video/Makefile | 3 + drivers/video/mipi_dbi.c | 467 +++++++++++++++++++++++ drivers/video/panel-ilitek-ili9341.c | 541 +++++++++++++++++++++++++++ drivers/video/stm32_ltdc.c | 336 +++++++++++++++++ drivers/video/stm32_ltdc.h | 130 +++++++ include/gpiod.h | 8 +- include/spi/spi.h | 20 + 10 files changed, 1542 insertions(+), 1 deletion(-) create mode 100644 drivers/video/mipi_dbi.c create mode 100644 drivers/video/panel-ilitek-ili9341.c create mode 100644 drivers/video/stm32_ltdc.c create mode 100644 drivers/video/stm32_ltdc.h -- 2.30.2 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
