Hi all, This is version 2 of the Cirrus Logic CS42L84 ASoC codec driver. This patch set adds a driver for the Cirrus Logic CS42L84 codec. This chip is (so far) found only on Apple Silicon Macs. In keeping with proud Apple tradition, the CS42L84 is essentially just a CS42L42 with a different regmap and no publicly available datasheet. It may also be missing its parent's S/PDIF capabilities as none of Apple's devices support S/PDIF out, however this cannot be positively confirmed. This driver has lived in the downstream Asahi tree for quite a while now, and gained some refinements along the way. I have squashed most of these into the initial driver commit as they were small changes like tweaking msleep()s or filling out TLVs, but left seperate a larger change to tip/ring sense IRQ handling as it differs significantly from what is found in the CS42L42 driver. --- Changes in v2: - Fixed failing DT binding checks. Sorry! (Patch 1) - Added Martin's name to the DT binding maintainer list (Patch 1) - Documented #sound-dai-cells property in DT binding (Patch 1) - Dropped superfluous DT binding descriptions (Patch 1) - Fixed DT binding description whitespace (Patch 1) - Fixed licence comment format in cs42l42.h (Patch 2) - Fixed erroneous whitespace in cs42l84.h (Patch 2) - Switched driver to use maple tree for regcache (Patch 2) - Lowered max_register property to address of highest observed register (Patch 2) - Fixed switch/case statement style (Patches 2, 3) - Picked up Neal's Reviewed-by - Link to v1: https://lore.kernel.org/r/20241016-cs42l84-v1-0-8d7e9d437d2d@xxxxxxxxx --- James Calligeros (1): ASoC: cs42l84: leverage ring sense IRQs to correctly detect headsets Martin Povišer (2): dt-bindings: sound: Add CS42L84 codec ASoC: cs42l84: Add new codec driver .../bindings/sound/cirrus,cs42l84.yaml | 56 ++ MAINTAINERS | 2 + sound/soc/codecs/Kconfig | 7 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cs42l84.c | 1112 +++++++++++++++++++++++++ sound/soc/codecs/cs42l84.h | 210 +++++ 6 files changed, 1389 insertions(+) --- base-commit: 469819cc17368702a6f68cec2148f518d3f3679b change-id: 20241016-cs42l84-f38348d21c88 Best regards, -- James Calligeros <jcalligeros99@xxxxxxxxx>
