Is that what you wanted to see in pinctrl-bindings.txt, or is there
something else you want to see added to that txt file?  I didn't want to add
the description of slew-rate arguments there because this is capri-specific.
I'm not quite sure what else to add.

That doc already says bias-pull-up is specified in Ohm, and the specific
values are chip-specific, so I don't think they should be mentioned there.

You're right, forget about this. I didn't realize the pinctrl bindings doc
was that good...

+Optional Properties (for HDMI pins):
+
+- function:                    String. Specifies the pin mux selection.
Values
+                               must be one of: "alt1", "alt2", "alt3",
"alt4"
+- slew-rate:                   Integer. Controls slew rate.
+                                       0: Standard(100kbps)&
Fast(400kbps) mode
+                                       1: Highspeed (3.4Mbps) mode

Hmmmm slew rate is not specifiec in "bps" but rather in
something like volts per second. But maybe it's best to keep
this value driver-specific.

Right, I think the slew-rates values are capri specific.

OK


Great! Is there anything else you would like to see changed before this patchset can be accepted?

Thanks,
Sherman
