Subject: spi: Make data format a PD option, add annotation types.
X-Git-Tag: libsigrokdecode-0.3.0~318
X-Git-Url: http://sigrok.org/gitweb/?p=libsigrokdecode.git;a=commitdiff_plain;h=3eda7779a7db58d76f0512940da7f6d7e4339731

spi: Make data format a PD option, add annotation types.

The data format can be specified via the PD's "format" option now, it is
no longer an annotation type.

Also, add and use two annotation types: "Data" and "Warnings".
