| * ASoC: fsl: micfil: Use dual license micfil codeDaniel Baluta2023-08-031-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need this in order to easily reuse register definitions and some functions with Sound Open Firmware driver. According to Documentation/process/license-rules.rst: "Dual BSD/GPL" The module is dual licensed under a GPL v2 variant or BSD license choice. The exact variant of the BSD license can only be determined via the license information in the corresponding source files. so use "Dual BSD/GPL" for license string.

* | ASoC: fsl_micfil: Add fsl_micfil_use_verid functionChancel Liu2023-08-021-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | fsl_micfil_use_verid() can help to parse the version info in VERID and PARAM registers. Since the two registers are added only on i.MX93 platform, a member flag called use_verid is introduced to soc data structure which indicates acquiring MICFIL version.

* ASoC: fsl_micfil: Add Hardware Voice Activity Detector supportShengjiu Wang2022-10-171-1/+5
| | | | | | | | | | | | | | | | | | The Hardware Voice Activity Detector (HWVAD) is a block responsible for detect voice activity in a channel selected by the user. It can be configured in Envelope-based or Energy-based mode. There are additional two interrupts for HWVAD, one is event interrupt, another is error interrupt. Enable hwvad in parallel with recording. when voice activity detected, HWVAD will be disabled and alsa control notification is triggerred.

* ASoC: fsl_micfil: change micfil default settingsShengjiu Wang2022-06-291-0/+9
| | | | | | | | | | | | | | Previous default settings resulted in loose dynamic range and low sound level.

* ASoC: fsl_micfil: use define for OSR default valueSascha Hauer2022-04-191-1/+0
| | | | | | | | | | | | The OSR (OverSampling Rate) setting is set once to the default value and never changed throughout the driver. Nevertheless the value is read back from the register for further calculations. Just use the default value because we know what we have written.

| | | | | | | | | | Use GENMASK along with FIELD_PREP and FIELD_GET to access bitfields in registers to straighten register access and to drop a lot of defines.
