This kernel is the 1rst one to support APF938 and coming soon APF27

2.6.27.3

  • CAN:
    • Now CAN infrastructure is integrated into mainline.
  • RTC:
    • RTC (DS1374) is now integrated to mainline (Driver seems more complete than our previous patch). legacy driver is still operational for 2.6.27 :-)
  • USB Host:
    • ISP176x seems to be integrated in Linux but seems "lighter" than ours (NXP). So we will keep NXP one.


No more used patches:

  • CAN related:
  • RTC related:
