This series adds support for two NeoFidelity amplifiers. For both amplifiers vendor provides software for equalizer and filters configuration, which generates firmware files with registers values. Since in both cases those files have same encoding, a common helper module is added to get firmware via request_firmware() API and set registers values. Changes in V3: - Added clocks to bindings and drivers - removed unused includes - ntp8835_reset_gpio() now only implements reset sequence and does not leave device in reset state - make data const where possible - Link to V2: https://lore.kernel.org/lkml/20240709221203.92167-5-ivprusov@xxxxxxxxxxxxxxxxx/ Changes in V2: - Fix dt_binding_check errors - Link to V1: https://lore.kernel.org/all/20240709172834.9785-1-ivprusov@xxxxxxxxxxxxxxxxx/ --- Igor Prusov (6): dt-bindings: vendor-prefixes: Add NeoFidelity, Inc ASoC: codecs: Add NeoFidelity Firmware helpers ASoC: dt-bindings: Add NeoFidelity NTP8918 ASoC: codecs: Add NeoFidelity NTP8918 codec ASoC: dt-bindings: Add NeoFidelity NTP8835 ASoC: codecs: Add NeoFidelity NTP8835 codec .../bindings/sound/neofidelity,ntp8835.yaml | 73 ++++ .../bindings/sound/neofidelity,ntp8918.yaml | 70 +++ .../devicetree/bindings/vendor-prefixes.yaml | 2 + sound/soc/codecs/Kconfig | 13 + sound/soc/codecs/Makefile | 6 + sound/soc/codecs/ntp8835.c | 480 +++++++++++++++++++++ sound/soc/codecs/ntp8918.c | 397 +++++++++++++++++ sound/soc/codecs/ntpfw.c | 137 ++++++ sound/soc/codecs/ntpfw.h | 23 + 9 files changed, 1201 insertions(+) --- base-commit: c7fbbb45ef78ff349d16923b516bc8667367d1a6 change-id: 20240924-ntp-amps-8918-8835-1fb126809fa3 Best regards, -- Igor Prusov <ivprusov@xxxxxxxxxxxxxxxxx>
