| | * usrp2: split compat number into major/minor (increment minor for fixes)Josh Blum2011-07-032-2/+2

| | * e100: proc_int should be high when interruptedJosh Blum2011-06-201-3/+1
| | |
| | * e100: added proc_int and buffer for async messagesJosh Blum2011-06-192-17/+49
| | | | | | | | | | | | | | | | | | | | | | | | Redirected the tx_err stream into a buffer_int2, and connected interrupt when a packet is written. The proc_int is muxed into the aux spi miso to use when its not being selected for spi.
