Subject: Re: [PATCH v4 3/6] mfd: ti_am335x_tscadc: Remove unwanted reg_se_cache save
Date: Fri, 21 Nov 2014 16:11:02 +0100 [thread overview]
Message-ID: <CAJKbBDDVTA+=priRu7sCD=vHrC8AUg4DM3kycuGrqbpF-5FGAA@mail.gmail.com> (raw)
In-Reply-To: <20141121131036.GA18931@localhost.localdomain>
I tested version 4 of the patch series on a custom design and I saw
also the jumps as described by Richard. I played a little with the
sample delay and it got better but I couldn't completely remove the
jumps.
The other issue I had with version 3, the pen_ups during the busy
loop, is solved. I experienced some pen_up misses during the busy loop
if I used a too high sample delay, without the sample delay it was ok.
Thanks,
Hannes
