[alsa-devel] [PATCH 4/4 v2] regulator: arizona-ldo1: Do not control clocking from regulator

[Charles Keepax]

From: Richard Fitzgerald <rf at opensource.wolfsonmicro.com>

Using the driver for the internal regulator to also control
the clock frequency of blocks inside the codec is an
unexpected side-effect for a regulator, and also means that
the core clocks won't be changed as expected if an external
regulator is used to power the codec.

The clocking control is now handled by the core arizona MFD
driver so can be removed from the LDO1 driver.
