From 3d7719d3cc8efe88be4c72cb7cbb0d866ed7d1b2 Mon Sep 17 00:00:00 2001 From: Hans de Goede Date: Sun, 25 Feb 2018 11:46:53 +0100 Subject: [PATCH] ASoC: rt5651: Only configure LDO voltage once at boot Now that rt5651_set_bias_level(BIAS_OFF) no longer modifies the LDO voltage selection bits, there is no need to set them each time we move to standby. Instead configure them once at component-probe() time.
