Subject: [PATCH 05/13] IB/hfi1: Extend i2c timeout
Date: Sun, 25 Sep 2016 07:41:25 -0700 [thread overview]
Message-ID: <20160925144123.10261.33941.stgit@scvm10.sc.intel.com> (raw)
In-Reply-To: <20160925143656.10261.85231.stgit-9QXIwq+3FY+1XWohqUldA0EOCMrvLtNR@public.gmane.org>
From: Dean Luick <dean.luick-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org>
Allow a longer timeout for i2c due to clock stretching and
inaccurate jiffy timing when under a spin lock. This timeout
is consistent with other i2c-algo-bit users.
