[PATCH 0/3] Add support for CH1115 Controller

This series add support for the CH1115 Controller [1].
It is a monochrome dot matrix OLED controller that supports several
interfaces such as SPI and I2C.

This driver only supports the I2C interface, but all common parts could
easily be put into a common file to be used with other interfaces.
I only have I2C to test with.

This is the first driver I write. The work is based on the driver
located at:
- drivers/gpu/drm/sitronix/st7571-i2c.c
- drivers/gpu/drm/sitronix/st7571.c

Tested with Raspberry Pi 3b+.

Thanks,
Nicolás
