i2c: gpio: add fault injector
Add fault injection capabilities to the i2c-gpio driver. When connected to another I2C bus, it can create unusual states which the other I2C bus master driver needs to handle. Only for debugging! Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com>

arch-neutral GPIO API to control the SCL and SDA lines.

+ This adds some functionality to the i2c-gpio driver which can inject

+ This is for debugging. If unsure, say 'no'.
