I am interested in modifying ixp4xx_hss so that 4*32 channels can be
used for each hss device.

I assume you mean 4 multiplexed E1 (with an external multiplexer/framer).

Sure. Sorry for not having stated it properly.

My first option is to modify the "defines" placed in the driver, but I
wonder if it would be useful to modify hss_plat_info to set this kind
of info.

I think we should add some "physical mode" parameter - single channel
(such as E1, T1 etc), 4 * E1, and any other (4 * T1 which is IIRC
special) when needed.

This is a great idea. Lots of parameters are related, so setting this
"physical mode" should be enough to configure the rest. I will try to
prepare a simple patch in order to comment if the ideas are correct.

It can go into hss_plat_info - a fixed(?) HSS port property.

Yes... I think it could be enough to make it a fixed property at the
moment. Maybe it could be added to sysfs in the future.
