From 02890535269338a6d2034ad3ce8b22beb24b449a Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 27 Sep 2011 11:08:48 +0200 Subject: ASoC: ssm2602: Support setting the oscillator and the clock output state Currently the oscillator is always enabled and the clock output is always disabled. This patch adds support for controlling the oscillator and clock output state through snd_soc_dai_set_sysclk. Which makes it possible to disable or enable them dynamically according to the requirements of the board on which the CODEC is used. This patch also slightly modifies the behavior as to when the oscillator is going to be disabled in low-power states. Previously it would only be disabled in BIAS_OFF, now it is also going to be disabled in BIAS_STANDBY, since no components which depend on it should be active in this state.
