[PATCH] arm: mvebu: x240: Use i2c-gpio instead of built in controller

2023-07-19 Thread Chris Packham
There is an Errata with the built-in I2C controller where various I2C hardware errors cause a complete lockup of the CPU (which eventually results in an watchdog reset). Put the I2C MPP pins into GPIO mode and use the i2c-gpio driver instead. This uses a bit-banged implementation of an I2C
