From 0182dcc52c759d005cc3e65deadee9f166cdd7d0 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Mon, 17 Aug 2009 18:51:44 +0100 Subject: [PATCH] ASoC: Fix WM8993 MCLK configuration for high frequency MCLKs When used without the PLL we were accidentally clearing the MCLK/2 divider, resulting in a double rate SYSCLK when the divider should have been used.
