Subject: [PATCH v4 12/31] i2c: tegra: Move out all device-tree parsing into tegra_i2c_parse_dt()
Date: Sat, 5 Sep 2020 23:41:32 +0300 [thread overview]
Message-ID: <20200905204151.25343-13-digetx@gmail.com> (raw)
In-Reply-To: <20200905204151.25343-1-digetx@gmail.com>
Move out code related to device-tree parsing from the probe function into
tegra_i2c_parse_dt() in order to make code more consistent.
