From 35a730a0790b2a6535e0b4a964c6a8b2d27fa019 Mon Sep 17 00:00:00 2001 From: Charles Keepax Date: Wed, 9 Jul 2014 17:41:45 +0100 Subject: [PATCH] ASoC: arizona: Correct relationship between VCO corner and Fref When configuring the FLL we must ensure that the reference clock passed to the FLL is under a certain limit. This limit was specified incorrectly in the current code, this patch corrects this. Although the error will only be encountered in some edge cases.
