Linux drivers for Wolfson devices

Wolfson provides Linux drivers for a wide range of its products in Linux and works to include these drivers in the standard Linux kernel in order to reduce integration and maintenance costs for users. These drivers use the standard Linux subsystems for the functionality provided by the Wolfson devices, where no standard framework exists Wolfson has contributed frameworks to the kernel. Since standard APIs are used these drivers will work with any processor with Linux support.

The latest versions of our drivers are available from this web site, please see below for details.

Audio CODECs

The audio functionality of our devices is supported by the ASoC framework within ALSA. Updates and drivers not yet merged into the standard Linux kernel are available from our ASoC repository.

AudioPlus PMICs

Our AudioPlus Power Management ICs support a wide range of functionality, crossing a range of kernel subsystems. All updates for this support are available from our AudioPlus repository.

AC97

The audio features of our AC97 devices are supported within both ASoC and the general Linux AC97 interface. Additional features, including touchscreen controllers and battery monitoring, are provided from our touchscreen repository.

Supported devices

This table lists currently supported devices. Where drivers have been merged into to the standard kernel the earliest version where the driver appears is also listed. Some additional devices such as ADC or DAC only variants may also be supportable using these drivers.
