From cca851d7b4d87f3a644d3381930dc737890bd9ac Mon Sep 17 00:00:00 2001 From: Ben Dooks Date: Mon, 28 Jan 2008 13:01:30 +0100 Subject: [PATCH] [ARM] 4790/1: S3C2412: Fix parent selection for msysclk. The msysclk clock was checking for the wrong PLL for the parent in s3c2412_setparent_msysclk(), trying the UPLL instead of the MPLL output. Also ensure the mpll and fclks are at the same rate at init time.
