Subject: [PATCH 0/4] i2c octeon & thunderx bug fixes
Date: Fri, 9 Dec 2016 10:31:54 +0100 [thread overview]
Message-ID: <20161209093158.3161-1-jglauber@cavium.com> (raw)
Hi Wolfram,
Patches #1 & #2 contain the fixes that didn't make 4.9.
We've double-checked that they are working on Octeon MIPS cn71xx,
so I hope there are no surprises this time.
Patch #3 is my original attempt on limiting the number of
retries for the i2c device register access. As I found out we
need to keep this simple, because these functions are called
very early in the i2c driver and also from all types of context.
Patch #4 addresses a bug report I got. I haven't seen this myself,
but apparently depending on probing method and/or hardware type
ipmi_ssif can fail to detect the IPMI device. Setting the class
in the adapter solves the problem and seems harmless.
Tested on MIPS Octeon CN71xx and ARM64 ThunderX on 4.9-rc8.
thanks,
Jan
