Hi all, 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. --- 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 Documentation/devicetree/bindings/sound/cirrus,cs42l84.yaml | 60 +++++++ MAINTAINERS | 2 + sound/soc/codecs/Kconfig | 7 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/cs42l84.c | 1110 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/cs42l84.h | 210 +++++++++++++++++++++++++ 6 files changed, 1391 insertions(+) --- base-commit: 469819cc17368702a6f68cec2148f518d3f3679b change-id: 20241016-cs42l84-f38348d21c88 Best regards, -- James Calligeros <jcalligeros99@xxxxxxxxx>
