ASoC updates in 3.6

Linux v3.6 was another quiet release for ASoC with just a single notable framework feature being merged: Added the ability to add and remove DAPM paths dynamically, mostly for reparenting on clock changes. New machine drivers for Marvell Brownstone, ST-Ericsson Ux500 and ttc-dkp. New CPU drivers for Blackfin BF6xx SPORTs in I2S mode, Marvell MMP, […]

regulator updates in 3.6

Linux 3.6, which was released earlier today, saw continuing improvements in the factoring out of common code in the API – lots of new features making drivers smaller and easier to write! Initial framework support for GPIO controlled enable signals, saving a bunch of code in drivers. Move fixed regulator enable time and voltage mapping […]

ASoC updates in 3.5

The big news for ASoC in 3.5 is the first two changes here which are pretty major features for the subsystem: Dynamic PCM support, allowing support for SoCs with internal routing through components with tight sequencing and formatting constraints within their internal paths or where there are multiple components connected with CPU managed DMA controllers […]

Regulator updates in 3.5

There’s been a bit of an increase in the amount of core work in version 3.5, regmap has enabled a lot of code to be factored out of drivers and into the core so drivers only need to provide data. This makes things a lot simpler to implement and review, it’s hoped that it will […]

regulator updates in 3.4

This has been a fairly quiet release from a regulator point of view, the only real framework features added were devm support and a convenience helper for setting up fixed voltage regulators. Much more coming next time, though! The most noticeable thing in the changelog is that Axel Lin continued his relentless and generally awesome […]

ASoC updates in 3.4

Linux version 3.4 has been released. This was a very active release for ASoC in framework terms, in addition to the usual bug fixes and so on there were a large number of framework enhancements though most are fairly small or are laying the groundwork for more user visible features like dynamic PCM. Support for […]

ASoC updates in 2.6.39

Linux 2.6.39 was released earlier today. This release includes a few updates, the main user visible one being that machine drivers can now be registered as regular devices rather than using the soc-audio device. Support for registering machine drivers as first class devices rather than using the soc-audio device. Support for the soc-audio device will […]
