The spec for the pca954x was missing. This chip is the same as the pca9540 except that it has interrupt lines. While the i2c_device_id table mapped the pca9542 to the pca9540 definition the compatible table did not. In preparation for irq support add the pca9542 definition.
A new ACPI table was added behind your back, which needs the same treatment as the i2c table. With that fixed, Acked-by: Peter Rosin <redacted> Cheers, peda
