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+.
