kernel/include/sound/wm9090.h, branch linux-5.1.y Hosts the 0x221E linux distro kernel. https://universe.0xinfinity.dev/distro/kernel/atom?h=linux-5.1.y 2010-04-30T15:12:44Z ASoC: Add WM9090 amplifier driver 2010-04-30T15:12:44Z Mark Brown broonie@opensource.wolfsonmicro.com 2010-04-28T17:36:10Z urn:sha1:39b8eab7e7fe429d8d57f18c0ebdb7c25df55f5c The WM9090 is a high performance low power audio subsystem, including headphone and class D speaker drivers. Note that this driver is a standalone CODEC driver and so is only immediately suitable for use with the WM9090 as a standalone sound card taking line inputs, or with a DAC with no software control. The pending ASoC multi-CODEC support will expand the range of systems that can use the driver, or system-specific adaptations can be made.
