Subject: [PATCH 3.16.y-ckt 243/254] pinctrl: dra: dt-bindings: Fix output pull up/down

3.16.7-ckt2 -stable review patch.  If anyone has any objections, please let me know.

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

From: Roger Quadros <rogerq@...com>

commit 73b3a6657a88ef5348a0d69c9a8107d6f01ae862 upstream.

For PIN_OUTPUT_PULLUP and PIN_OUTPUT_PULLDOWN we must not set the
PULL_DIS bit which disables the PULLs.

PULL_ENA is a 0 and using it in an OR operation is a NOP, so don't
use it in the PIN_OUTPUT_PULLUP/DOWN macros.

Fixes: 23d9cec07c58 ("pinctrl: dra: dt-bindings: Fix pull enable/disable")
