2015-04-10aha1542: remove loop from aha1542_outbOndrej Zary1-8/+5
The loop in aha1542_outb with double-check is no longer needed, remove it. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: James Bottomley <JBottomley@Odin.com>
2015-04-10aha1542: Fix bus resetOndrej Zary1-1/+1
Bus reset always fails because aha1542_reset waits for the controller to assert the INIT bit (Mailbox Initialization Required) which it never does. This bit is asserted only after host reset. Remove the requirement for INIT bit (we really need only the IDLE bit).

2015-04-10aha1542: rework lockingOndrej Zary1-84/+34
Remove aha1542_lock and use host_lock instead. Remove interrupt and queuecommand function wrappers. Remove locking from lowlevel _out and _in functions, they now can onle be called (at runtime) with host_lock being held. Remove ssleep(4) in aha1542_reset as we can't sleep while holding a spinlock. It's useless anyway as wait_mask will wait until the controller is idle and kernel waits for 10 seconds (HOST_RESET_SETTLE_TIME) after that.
