   ## Summary
   This adds DMA and Timer/counter support to SAMv7 AFEC (ADC) driver. The AFEC (ADC) can now be triggered by Timer/counter at chosen frequency and samples can be transfered via DMA with configurable number of samples. Timer/counter trigger is now set as a default option with the possibility to change it to software generated trigger. These changes are included in commit 79c645d.
   
   Update to SAME70-XPLAINED adc defconfig to refer to these changes is also included in commit ce3e8c0.
   
   Commit c2b0664 just fixes few compile errors and warnings that occured in sam_tc.c file.
   
   ## Impact
   SAMv7 AFEC driver only, should not impact any other drivers.
   
   ## Testing
   Tested with SAME70-XPLAINED evaluation board and with custom board based on SAME70 MCU.
