From ece509c10985ba93ccc8c68f808a9e767250041c Mon Sep 17 00:00:00 2001 From: Dylan Reid Date: Mon, 3 Nov 2014 10:28:56 -0800 Subject: ASoC: max98090: Correct pclk divisor settings The Baytrail-based chromebooks have a 20MHz mclk, the code was setting the divisor incorrectly in this case. According to the 98090 datasheet, the divisor should be set to DIV1 for 10 <= mclk <= 20. Correct this and the surrounding clock ranges as well to match the datasheet.
