From ebbfabc16d23dfd20eecd4b6e68212fec37ae7c6 Mon Sep 17 00:00:00 2001 From: Derek Fang Date: Tue, 18 Feb 2020 21:51:51 +0800 Subject: ASoC: rt5682: Add CCF usage for providing I2S clks There is a need to use RT5682 as DAI clock master for other codecs within a platform, which means that the DAI clocks are required to remain, regardless of whether the RT5682 is actually running playback/capture. The RT5682 CCF basic functions are implemented almost by the existing internal functions and asoc apis. It needs a clk provider (rt5682 mclk) to generate the bclk and wclk outputs. The RT5682 CCF supports and restricts as below: 1. Fmt of DAI-AIF1 must be configured to master before using CCF. 2. Only accept a 48MHz clk as the clk provider. 3. Only provide a 48kHz wclk and a set of multiples of wclk as bclk. There are some temporary limitations in this patch until a better implementation.
