Subject: [RFC PATCH v2 7/7] i2c: algo: bit: HACK! add atomic callback
Date: Sat, 2 Mar 2019 14:47:35 +0100 [thread overview]
Message-ID: <20190302134735.4393-8-wsa+renesas@sang-engineering.com> (raw)
In-Reply-To: <20190302134735.4393-1-wsa+renesas@sang-engineering.com>
This is only for testing and will work only for bitbanging which is done
without generating irqs. Not for upstream!
