drm: Add driver for Sitronix ST7920 LCD displays

2025-12-15T17:25:09+00:00

Add a new DRM/KMS driver for displays using the Sitronix ST7920 controller connected via the SPI bus. This provides a standard framebuffer interface for these common monochrome LCDs.

drm/sitronix: st7571-i2c: Select VIDEOMODE_HELPERS

2025-06-11T08:44:56+00:00

This driver requires of_get_display_timing() from CONFIG_VIDEOMODE_HELPERS but does not select it. If no other driver selects it, there will be a failure from the linker if the driver is built in or modpost if it is a module. ERROR: modpost: "of_get_display_timing" [drivers/gpu/drm/sitronix/st7571-i2c.ko] undefined! Select CONFIG_VIDEOMODE_HELPERS to resolve the build failure.

drm/sitronix: Remove broken backwards-compatibility layer

2025-05-27T08:21:51+00:00

When moving the Sitronix DRM drivers and renaming their Kconfig symbols, the old symbols were kept, aiming to provide a seamless migration path when running "make olddefconfig" or "make oldconfig". However, the old compatibility symbols are not visible. Hence unless they are selected by another symbol (which they are not), they can never be enabled, and no backwards compatibility is provided. Drop the broken mechanism and the old symbols.

We start to have support many Sitronix displays in the tiny directory, and we expect more to come. Move them to their own subdirectory.
