Dear Mike Frysinger,

The problem is, that without blowing up the parser even more, only
2 forms of the command are valid:

the classic form

<cs> <bit_len> <dout>

or

<bus>:<cs>[.<mode>] <bit_len> <dout>

Since this command is mainly used for testing/debugging hardware,
I saw no need to allow the form

<cs>.<mode> <bit_len> <dout>

If thats ok, I can make a patch with the help fixed.

Best Regards
Reinhard
