  • Support for low power Backup+Self-Refresh mode for SAMA5D2 and the SAMA5D2 Xplained board
  • SAMA5D2: most of the driver converted to support the Backup+Self-Refresh mode
  • Low power modes: use of kernel command line parameters to choose the Power Management scheme (ULP0, ULP1, Backup+Self-Refresh)
  • Addition of the new SAMA5D27 SOM1 EK board containing the SAMA5D27 SiP
  • SAMA5D4: addition of the G1 Video Decoder (Vdec) drivers
  • Kernel configuration: Use of the High resolution timers option by default
  • Kernel configuration: Use of the tick-less system configuration by default
  • Kernel configuration: Use of CONFIG_JUMP_LABEL for improving network performance
  • SAMA5D2: ADC add hardware trigger and buffer support
  • SAMA5D2: ISC: format configuration enhancement
  • Addition of another camera sensor: the ov7670
  • Addition of several peripherals in device tree: CAN, PWM for instance
  • fixes: SAMA5D4-compatible watchdog, SAMAD2 LCD drive strength on base signals, use of CPU I/O for SAM9 SPI controller, USB host vbus on SAMA5D2
