From 5d3d305c2ec0128719a2e7f5e7b2cc37cf4e7da6 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.
