From: Martin Povišer
Date: Tue May 31 2022 - 17:52:40 EST


Hi,

I am doing another push of this neglected series which adds support for
Audio DMA Controller on recent Apple SoCs.

All best,
Martin


Changes since v3:
- collected Rob's r-b tag on binding
- split off MAINTAINERS commit for easier merging (allegedly)

Changes since v2:
(link: https://lore.kernel.org/dmaengine/20220411222204.96860-1-povik+lin@xxxxxxxxxxx/ )
- 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@xxxxxxxxxxx/ )
- 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
device_synchronize
- minor fixes (comments, formatting)
