| |
tested with: CONFIG_I2C_MXS=m CONFIG_I2C_MXS=y
in combination with CONFIG_GPIO_MXS enabled and disabled
used kernels: 3.6 and 3.7.0-rc6
My I2C slave is a PCF8575 i/o expander with some LEDs at the output. These are controlled through sysfs.
Just tested with "i2cdetc -y -r 0" that crashes with "BUG: soft lockup - CPU#0 stuck for 22s!" according to the docs (IMX23RM.pdf) the interrupts for I2C are 26 and 27 that why I assigned these two in the dts.
