From d61100bbd18e8b3fc9406be55354dabd5e7525ec Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 14 Dec 2012 15:16:58 +0900 Subject: [PATCH] ASoC: wm2000: Use clock API integration to configure MCLK divisor Since we are now using the clock API integration to manage MCLK we can now use clk_get_rate() to determine if we need to divide MCLK without relying on platform data.
