  • [22:21:23] <ds2> is the McBSP the master or slave in the 810?
  • [22:21:43] <ds2> most TWL4030 driver use the McBSP as the master
  • [22:28:11] <sakoman> grumble . .. mcbsp in git only supports omap1 and omap2420 :-(
  • [22:28:23] <sakoman> * TODO: Add support for 2430 and 3430
  • [22:28:47] <ds2> DOH
  • [22:29:00] <ds2> but the good news is 2430 + 3430 McBSP is almost the same ;)
  • [22:29:23] <ds2> and I think the older before reorg McBSP code supported both the 2430 and the older 2420 stuff
  • [22:30:05] <sakoman> ah, pending patches seem to start to address this
