From: Linus Walleij linus.walleij@linaro.org
[ Upstream commit c2a736b698008d296c5010ec39077eeb5796109f ]
The moxart interrupt line flags were not respected in previous driver: instead of assigning them per-consumer, a fixes mask was set in the controller.
With the migration to a standard Faraday driver we need to set up and handle the consumer flags correctly. Also remove the Moxart-specific flags when switching to using real consumer flags.
Extend the register window to 0x100 bytes as we may have a few more registers in there and it doesn't hurt.
