Subject: [PATCH] regulator: lp8755: Provide map_voltage()
Date: Tue, 2 Jul 2013 23:58:38 +0100 [thread overview]
Message-ID: <1372805918-15128-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
Improve performance when setting voltages by avoiding a scan through the
selectors when we can simply calculate the selector we want.
