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@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) Thanks, Martin Martin Povišer (2): dt-bindings: dma: Add Apple ADMAC dmaengine: apple-admac: Add Apple ADMAC driver .../devicetree/bindings/dma/apple,admac.yaml | 75 ++ MAINTAINERS | 2 + drivers/dma/Kconfig | 8 + drivers/dma/Makefile | 1 + drivers/dma/apple-admac.c | 818 ++++++++++++++++++ 5 files changed, 904 insertions(+) create mode 100644 Documentation/devicetree/bindings/dma/apple,admac.yaml create mode 100644 drivers/dma/apple-admac.c -- 2.33.0
