This is a very similar commit message to the one that Tao sent out, so
I thought for a moment that it was a duplicate patch. I can see now
that it's a different change.

Reviewed-by: Joel Stanley <joel at jms.id.au>
Fixes: ab4a85534c3e ("gpio: aspeed: Add in ast2600 details to Aspeed driver")

Cheers,

Joel
