Subject: [PATCH v2 4/5] ARM: dts: omap5: describe control for ckobuffer

OMAP5 has a register to control if the ckobuffer is enabled
and defines the polarity. ckobuffer is required to drive a twl6040
with the system clock. Hence, add the pinctrl,single to the
OMAP5 SoC description so that omap5-board-common can
set up the ckobuffer as required.
