[PATCH 0/3] Add support for Sitronix ST7571 LCD controller
From: Marcus Folkesson
Date: Wed Apr 02 2025 - 02:12:53 EST
This series add support for the ST7571 LCD Controller.
It is a 4 gray scale dot matrix LCD controller that supports several
interfaces such as SPI, I2C and a 8bit parallell port.
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.
The device is a little defiant, it tends to NAK some commands, but all
commands takes effect, hence the I2C_M_IGNORE_NAK flag.
