From e8f112d8c29f44ded83f97828c104bf0904871ec Mon Sep 17 00:00:00 2001 From: Keyon Jie Date: Fri, 25 Oct 2019 17:40:59 -0500 Subject: [PATCH] ASoC: SOF: add set_power_state() to dsp_ops for power state update D0i3 is a platform-defined substate of D0, so we need a platform-specific callback in dsp_ops to handle the relevant configurations.
