Subject: [PATCH 0/6] drm/sitronix/st7571: split up driver to support both
 I2C and SPI

This series splits up the driver and finally implements
support for ST7571/ST7561 connected to a SPI bus.

I've not tested the SPI interface myself as I lack HW, but the
implementation should be okay from what I've read in the datasheet.
