Re: [alsa-devel] [PATCH v3] ASoC: Add support for NAU8825 codec to ASoC

Hi Chih-Chiang

The NAU88L25 is an ultra-low power high performance audio codec designed for smartphone, tablet PC, and other portable devices by Nuvoton, now add linux driver support for it.

At ChromeOS we work with Nuvoton hw engineers on driver for this nice chip as well.

Here is current driver code https://github.com/anatol/linux/blob/nau8825/sound/soc/codecs/nau8825.c

The functionality is mostly ready. Our driver handles playback, capture, mic jack detection, an button presses (4 buttons according Android specification). We need to resolve a few remaining issues, such as - chip needs better way to recognize high-impedance input (e.g. Bose Quiet Comfort 15 headset) - implement headset cross talk automatic configuration - general code cleanup

But otherwise driver is functional and used for testing in our next generation device.

What do you think about joining efforts on this software development to make great driver for this chip?

v3->v2:

• fix the wrong definition of reg_default
• fix the flow of set_sys_clk() and nau8825_set_bias_level()
• remove unnecessary code in nau8825_volatile_register() and

nau8825_i2c_probe()

• add trigger function for ADC/DAC control
• add some register definitions
• fix some coding style issues

v2->v1:

• fixes according to Lars-Peter Clausen's review comments
• removes unused platform data file
• corrects the naming of DAPM input widget
• fixes some wrong coding of SOC widgets and other codes
• adds definition and remark for config FLL clock
• moves the code of reset hardware registers from codec_probe() to

i2c_probe()

• removes unused codes
