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.

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 […]

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 […]

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 […]

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 […]
