Subject: [PATCH] regulator: ab8500: Provide map_voltage() functions
Date: Wed, 3 Jul 2013 10:16:32 +0100 [thread overview]
Message-ID: <1372842992-18712-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
Since all the voltage tables for ab8500 are sorted in ascending order we
can improve performance by using regulator_map_voltage_ascend(). A couple
of the regulators can actually use linear maps which would be even better.
