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!
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
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
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
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
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
regmap - a register map abstraction for the Linux kernel A good proportion of I2C and SPI device drivers in the kernel contain some very similar code for accessing the register maps of hardware connected to those buses – most hardware designers have solved the problem of providing very similar ways. Linux 3.1 introduces a new kernel API called regmap
