From f844ea32cba0c4030594a0f590725477a5751f32 Mon Sep 17 00:00:00 2001 From: Annaliese McDermond Date: Thu, 21 Mar 2019 17:58:49 -0700 Subject: [PATCH] ASoC: tlv320aic32x4: Control clock gating with CCF commit d25970b5fd51e9fcf0afbe190908ea4049454da4 upstream. Control the clock gating to the various clock components to use the CCF. This allows us to prepare_enalbe only 3 clocks and the relationships assigned to them will cause upstream clockss to enable automatically. Additionally we can do this in a single call to the CCF.
