Hi, Here are two patches for the mcp23s08 driver adding proper support for the pull-up resistors. The regmap conversion was mainly done to improve the debugging capabilities, but is also a nice cleanup. Further cleanups could be done by using regmap's caching instead of the open-coded one.
The patches were tested with a couple of mcp23017 connected to the I²C bus of an RPi (and modified DT). -- Sebastian Sebastian Reichel (2): gpio: mcp23s08: use regmap gpio: mcp23s08: add pinconf support drivers/gpio/gpio-mcp23s08.c | 430 ++++++++++++++++++++++++++----------------- 1 file changed, 261 insertions(+), 169 deletions(-) -- 2.11.0
