Open-source support for Wolfson Microelectronics parts has now moved to the Cirrus Logic GitHub area: http://github.com/cirruslogic/
Please transfer over to using the GitHub repositories. We will keep opensource.wolfsonmicro.com active for a period to allow users to transition across to GitHub. Eventually opensource.wolfsonmicro.com will be closed down.

An initial Linux driver for the WM0010, a compact digital signal processor that has been highly optimised for low-power audio applications. Extensive memory resources and core optimisation allow the device to manage all audio processing algorithms efficiently and autonomously, while the host processor sleeps or performs other tasks. Like all Wolfson drivers this can be obtained via our ASoC page.

An initial Linux driver for the WM5110, a highly-integrated low-power audio system for smartphones, tablets and other portable audio devices which combines an advanced DSP feature set with a flexible, high-performance audio hub CODEC. Like all Wolfson audio drivers this can be obtained via our ASoC page. For more information on the WM5110 please see the main WM5110 product page.
