Hi all,

this is v3 of driver for Audio DMA Controller on recent Apple SoCs.

Changes since v3:
(link: https://lore.kernel.org/dmaengine/20220411222204.96860-1-povik+lin@cutebit.org/ )
 - in binding, make 'interrupts' fixed length and add a comment
 - do not use devm allocation on descriptors
 - use platform_get_irq_optional to not log errors in the course of looking for
   an usable interrupt
 - make channel no. unsigned

Changes since v1:
(link: https://lore.kernel.org/dmaengine/20220330164458.93055-1-povik+lin@cutebit.org/ )
 - in binding, drop 'apple,internal-irq-destination' in favor of
   prepending entries to 'interrupts'
 - drop admac_peek/poke helpers
 - use special versions of dev_err/WARN_ON where desirable, fix %pad
   formatter invocation
 - bring implementation of terminate_all up to dmaengine spec, add
 - minor fixes (comments, formatting)
