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, [...]

I will be speaking at ELC-E in Barcelona this year, with a talk entitled regmap: The Power of Subsystems and Abstractions. I look forward to seeing some of you at the conference, perhaps even in the audience!

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 [...]

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 [...]

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 [...]

Things are really quieting down with the regmap API, while we’re still seeing a trickle of new features coming in they’re getting much smaller than they were. Support for padding between the register and the value when interacting with the device. This is required by some devices with high speed control interfaces in order to [...]
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 [...]

Linux 3.3 was released today. This was the biggest release for the regulator API for quite some time thanks to the contribution of device tree bindings for the API by Rajendra Nayak, the first substantial framework update for a long time, but otherwise was fairly quiet: OpenFirmware bindings for the core and for the fixed regulator [...]

After the rush of new features in version 3.2 this has been a fairly quiet cycle for the regmap API, the main change being the wider usage by drivers. In terms of development of the subsystem itself this release sees: Introduction of a generic interrupt controller for regmap based devices, this is already used by [...]

Version 3.1 of the Linux kernel was the first release to include regmap support and only included a bare minimum of features in order to ease review so version 3.2 has been a pretty big one for regmap development with some pretty major features being built on top of the core code. Support for register [...]
