We made it PBGL instead of using BNLT. Thanks Jason, Yeah I must have got distracted and coped the one off "PocketBone" value, in v3 i have it changed to: +This board family can be indentified by the A335PBGL in the at24 eeprom: +A2: [aa 55 33 ee 41 33 33 35 50 42 47 4c 30 30 41 32 |.U3.A335PBGL00A2|] > Is there anything preventing the PRU and GPIO pins from being defined? I guess the GPIO pins might not be exposed through SYSFS due to lack of upstream drivers, but could the pinmux at least be set? Yeah, we could add those default pinmux's too like I did for spi, (we use a spidev node, but that can't go mainline) Regards,

One small comment, the copyright notices for 2012 seem a little unlikely to be 'complete'. I guess a lot is copied from files dating back that far, but not everything so do we not want to reflect more recent work on these?
