[PATCH v4 0/3] Add Broadcom STB memory controller driver

[Florian Fainelli]

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 v4:

- drop unnecessary owner assignment for the platform_driver
- use pm_ptr() as directed

Changes in v3:

- made 'frequency' property optional to avoid introducing warnings for
  existing BMIPS and BCM7445 DTS files
- updated sysfs document to use a shorter and universal path

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
