From 09ab15798a232d70824e60699f4c7c296234f82f Mon Sep 17 00:00:00 2001 From: Cheng-Yi Chiang Date: Wed, 1 Nov 2017 15:01:34 +0800 Subject: [PATCH] mb/google/eve: Add DSP calibration clock name/rate for RT5514 Add a property for DSP calibration clock name and rate such that RT5514 codec driver can control ssp1_mclk for DSP clock calibration. BUG=b:67763576 TEST=boot on eve check RT5514 codec driver can get this device property.
