Update the gpio name parsing code to try to search for without the

property name would work as before.
Why?
Why we want the older names to work? Just to make life easier if
backporting the drm driver to a downstream msm kernel (like a 3.10,
or 3.18).
Update the binding doc. Add an entry for the missing hpd and lpm
gpios.

hpd-gpios is the somewhat standard name.

+- mux-sel-gpio: hdmi mux select pin
+- mux-lpm-gpio: hdmi mux lpm pin
These look pretty QCom specific and should keep the vendor prefix.
Okay.
I understand why you don't have '-gpios', but if we change these they
should use the preferred form.
Sure, I'll update these to the preferred form.
