[PATCH 0/4] regmap: Generic I2C and SPI register map library

This is a version of a series I've been posting for most of this release cycle which abstracts out a bunch of widely duplicated code for doing register I/O on devices with control slow buses like I2C and SPI. As well as saving us code for the ...

[PATCH 0/8] regmap: Generic I2C and SPI register map library

[This revision of the series has some minor updates to the SPI code.] Many I2C and SPI based devices implement register maps on top of the raw wire interface. This is generally done in a very standard fashion by devices, resulting in a lot of very ...

[GIT PULL] regmap: Generic I2C and SPI register map library

This pull request adds regmap, a library which abstracts out some widely reimplemented code for accessing the register maps of devices on slow buses like I2C and SPI. As well as factoring out code this makes it much easier to factor out higher ...
