From 293076f300f52e1593b596b3f09ec057ee6e4a36 Mon Sep 17 00:00:00 2001 From: Manuel Lauss Date: Mon, 18 Aug 2014 17:10:32 +0200 Subject: MIPS: Alchemy: Fix db1200 PSC clock enablement Enable PSC0 (I2C/SPI) clock and leave PSC1 (Audio) alone. This patch restores functionality to both Audio and I2C/SPI.
