Hi Krzysztof,
This small patch series adds basic support for controlling self-refresh
power down on Broadcom STB memory controllers. We might be able to
contribute more features to the memory controller driver in the future
like accurate reporting of the memory type, timings, and possibly some
performance counters.
Changes in v2:
- merged the v1 first two patches
- added a sysfs document describing attributes exposed
- addressed feedback from Krzysztof regarding style and API usage
