Subject: [PATCH v2 0/3] iio: adc: sama5d2_adc hw triggers and buffers

This patch implements the hardware triggers support and buffer management
for sama5d2.
The DT modifications ( [PATCH 1/3] ARM: dts: at91: sama5d2_xplained:
enable ADTRG pin) are for demonstration purposes of the feature,
setting the pinctrl for the ADC hw trigger pin,should go through
at91 maintainers.
I also increased the buffer size for the trigger name in the
generic_buffer application to cope with longer names and avoid
stack smashing problem.
This is in patch [PATCH 3/3] iio: tools: generic_buffer: increase trigger length

  Changes in v2:
 - Moved buffer allocation and freeing into the preenable and postdisable
   callbacks.
   We have a total of scan bytes that can vary a lot depending on each channel
   enabled at a certain point.
 - made the at91 trigger list part of state structure
 - made the iio trigger list preallocated in state structure
 - moved irq enabling/disabling into the try_reenable callback
 - on trigger disable must write disable registries as well
 - Modified trigger name length to 64
