Why do you need to read registers?
What you actually might be interested in is the debugfs patches in
Viviens github tree.

EEInt should clear on read for older chips. For 6390, it might be
necessary to read global 2, register 0x13, index 03.

The EEInt bit is probably masked. So it will not generate in
interrupt.

Is it forever looping in mv88e6xxx_g1_irq_thread_work? Or is it the
polling code, mv88e6xxx_irq_poll() firing every 100ms?
