If the ATX-PSU POWER_GOOD input is connected to an PCA9554 I2C GPIO expander which is also connected to a shared I2C bus interrupt pin, then changes in the ATX-PSU POWER_GOOD state will block the I2C bus interrupts until the GPIO inputs are read.
Add support for multiple
gpio_i2c_dev
sharing the sameint_pin
.Move I2C GPIO timeout to the
gpio_i2c_dev
.Change
atx_psu
to use interrupts and polling for thepower_good
