Subject: [PATCH v2 2/2] hwrng: iproc-rng200 - Add Broadcom IPROC RNG driver
Date: Mon, 2 Mar 2015 16:50:59 -0800 [thread overview]
Message-ID: <54F50573.3040506@broadcom.com> (raw)
In-Reply-To: <20150225184338.GA3215@dtor-ws>
Hi Dmitry,
Looking at the driver based on your comments it is following models of
older hwrng drivers. I will work on cleaning up based on your comments
as well.

yes, will cleanup in other functions as well.

ok, it looks like you are commenting based on what is done in omap-rng.
I can follow that model and move this into an init function.
