[PATCH 0/3] drm/sitronix/st7571-i2c: Add support for the ST7567 Controller

[Javier Martinez Canillas <javierm@redhat.com>]

This patch-series adds support for the Sitronix ST7567 Controller, which is is a
monochrome Dot Matrix LCD Controller that has SPI, I2C and parallel interfaces.

The st7571-i2c driver only has support for I2C so displays using other transport
interfaces are currently not supported.

The DRM_FORMAT_R1 pixel format and data commands are the same than what is used
by the ST7571 controller, so only is needed a different callback that implements
the expected initialization sequence for the ST7567 chip.

Patch #1 adds a Device Tree binding schema for the ST7567 Controller.

Patch #2 makes the "reset-gpios" property in the driver to be optional since that
isn't needed for the ST7567.

Patch #3 finally extends the st7571-i2c driver to also support the ST7567 device.
