Hi,
The following series was inspired in part by http://marc.info/?l=linux-omap&m=140974309205295&w=2
causing me to try and do an audit of pinctrl configurations on the platform.
Further, failures on latest board updates in the automated farm also
caused identification of a fix which was yet to be send to upstream
from product kernel. Slightly unrelated patches in this series.
So here they are..
based on v3.17-rc1:
before-dra7xx-evm: Boot FAIL: http://paste.ubuntu.org.cn/1477597
(fails can be at different times though.. random crashes without VTT is usual)..
after-dra7xx-evm: Boot PASS: http://paste.ubuntu.org.cn/1477596

DRA7 evm REV G and later boards uses a vtt regulator for DDR3
termination and this is controlled by gpio7_11. This gpio is
configured in boot loader. gpio7_11, which is only available only on
Pad A22, in previous boards, is connected only to an unused pad on
expansion connector EXP_P3 and is safe to be muxed as GPIO on all
DRA7-evm versions (without a need to spin off another dts file).
Since gpio7_11 is used to control VTT and should not be reset or kept
in idle state during boot up else VTT will be disconnected and DDR
gets corrupted. So, as part of this change, mark gpio7 as no-reset and
no-idle on init.
