I just realized I screwed up the previous patch. I forgot to include the
change to set NumInstances to 2.
I found another issue I am had with the hostmot2 driver while using the
7i65 board with the way it determines how many encoder select pins to
allocate. In pins.c the encoder select pins are determined by how many
encoders there are,
// muxed encoder gets the sel pins
hm2_pins_allocate_all(hm2, HM2_GTAG_MUXED_ENCODER_SEL,
hm2->encoder.num_instances);
With this code if I set num_encoders to 8 emc for the 7I65 card it will
allocate the select pins from both connectors if using a 2x7i65
firmware. Here is the output from dmesg with num_encoders set to 8.

I'm still trying to wrap my head around hostmot's vhdl and emc's code
and am not sure how to fix it ( or did I screw something up? ).
