[PATCH 4.3 033/125] MIPS: ath79: Fix the DDR control initialization on ar71xx and ar934x

From: Greg Kroah-Hartman
Date: Mon Dec 07 2015 - 10:37:47 EST


4.3-stable review patch. If anyone has any objections, please let me know.

------------------

From: Alban Bedel <albeu@xxxxxxx>

commit 5011a7e808c9fec643d752c5a495a48f27268a48 upstream.

The DDR control initialization needs to know the SoC type, however
ath79_detect_sys_type() was called after ath79_ddr_ctrl_init().
Reverse the order to fix the DDR control initialization on ar71xx and
ar934x.
