74373977 - drm/solomon: Add SSD130x OLED displays SPI support

Tue, 19 Apr 2022 21:48:23 +0000

drm/solomon: Add SSD130x OLED displays SPI supportThe ssd130x driver only provides the core support for these devices but itdoes not have any bus transport logic. Add a driver to interface over SPI.There is a difference in the communication protocol when using 4-wire SPIinstead of I2C. For the latter, a control byte that contains a D/C# fieldhas to be sent. This field tells the controller whether the data has to bewritten to the command register or to the graphics display data memory.But for 4-wire SPI that control byte is not used, instead a real D/C# linemust be pulled HIGH for commands data and LOW for graphics display data.For this reason the standard SPI regmap can't be used and a custom .writebus handler is needed.Signed-off-by: Javier Martinez Canillas Acked-by: Mark Brown Reviewed-by: Geert Uytterhoeven Link: https://patchwork.freedesktop.org/patch/msgid/20220419214824.335075-6-javierm@redhat.com List of files: /linux-6.15/drivers/gpu/drm/solomon/Makefile

drm: Add driver for Solomon SSD130x OLED displaysThis adds a DRM driver for SSD1305, SSD1306, SSD1307 and SSD1309 SolomonOLED display controllers.It's only the core part of the driver and a bus specific driver is neededfor each transport interface supported by the display controllers.Signed-off-by: Javier Martinez Canillas Reviewed-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20220214133710.3278506-4-javierm@redhat.com List of files: /linux-6.15/drivers/gpu/drm/solomon/Makefile
