regmap updates in 3.6
Linux 3.6 was a very quiet release for regmap: Support for buses and devices specifying their endianness, providing some performance improvements for MMIO devices. Support for wake IRQs in regmap-irq.

Speaking at ELC-E: “regmap: The Power of Subsystems and Abstractions”
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!
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 […]
regmap updates in 3.5
A surprisingly large series of updates for regmap this time, mostly due to all the work Stephen Warren has done to add support for MMIO buses. This wasn’t really the target for the framework but it turns out that there’s a reasonable number of cases where it’s very helpful to use the register cache support to allow the register […]
regmap updates in 3.4
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 […]
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 3.3
Linux 3.3 was released earlier this week. Aside from a few regmap related updates it was an extremely quiet release for the ASoC framework, the next few releases look like they will be much more active: Conversion of a number of CODEC drivers to use regmap directly. This is especially beneficial for drivers for devices […]
regulator updates in 3.3
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 […]
regmap updates in 3.3
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 […]
regmap updates in 3.2
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 […]
