Subject: [PATCH v4 43/78] ncr5380: Standardize reselection handling
Date: Sun, 03 Jan 2016 16:05:44 +1100 [thread overview]
Message-ID: <20160103050512.412082402@telegraphics.com.au> (raw)
In-Reply-To: 20160103050501.042035135@telegraphics.com.au
[-- Attachment #1: ncr5380-standardize-reselection-handling --]
[-- Type: text/plain, Size: 10722 bytes --]
Bring the two NCR5380_reselect() implementations into agreement.
Replace infinite loops in atari_NCR5380.c with timeouts, as per NCR5380.c.
Remove 'abort' flag in NCR5380.c as per atari_NCR5380.c -- if reselection
fails, there may be no MESSAGE IN phase so don't attempt data transfer.
During selection, don't interfere with the chip registers after a
reselection interrupt intervenes.
Clean up some trivial issues with code style, comments and printk.
