From 8f48bb71889fa1380cece2034242d182097b6e9d Mon Sep 17 00:00:00 2001 From: Robin Gong Date: Thu, 21 May 2015 10:45:03 +0800 Subject: MLK-10957: ARM: mx6qp: do not turn off PU There is narrow window that PRE driver is ready but GPU driver probe later, and the later GPU driver turn on PU may cause 'PRE hang' issue. To simplify thing, do not turn off PU in u-boot.
