Subject: [PATCH 0/3] drm/sitronix/st7920: Add support for the ST7920
 controller

This patch-series adds support for the Sitronix ST7920 controller, which
is a monochrome dot-matrix graphical LCD controller that has SPI and
parallel interfaces.

The st7920 driver only has support for SPI so displays using other
transport protocols are currently not supported.

* Patch #1 adds the driver.
* Patch #2 adds the DT binding schema.
* Patch #3 adds the MAINTAINERS information.
