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 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 Florian Fainelli (3): dt-bindings: memory-controller: Document Broadcom STB MEMC Documentation: sysfs: Document Broadcom STB memc sysfs knobs memory: Add Broadcom STB memory controller driver .../ABI/testing/sysfs-platform-brcmstb-memc | 15 + .../bindings/arm/bcm/brcm,brcmstb.txt | 11 +- .../brcm,brcmstb-memc-ddr.yaml | 52 +++ drivers/memory/Kconfig | 9 + drivers/memory/Makefile | 1 + drivers/memory/brcmstb_memc.c | 302 ++++++++++++++++++ 6 files changed, 381 insertions(+), 9 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-platform-brcmstb-memc create mode 100644 Documentation/devicetree/bindings/memory-controllers/brcm,brcmstb-memc-ddr.yaml create mode 100644 drivers/memory/brcmstb_memc.c -- 2.25.1
