Subject: [PATCH v3 0/4] Broadcom STB S2/S3/S5 support for ARM and MIPS

Hi,

This patch series adds support for S2/S3/S5 suspend/resume states on
ARM and MIPS based Broadcom STB SoCs.

This was submitted a long time ago by Brian, and I am now picking this
up and trying to get this included with support for our latest chips.

Provided that I can collect the necessary Acks from Rob (DT) and other
people (Rafael?) I would probably take this via the Broadcom ARM SoC
pull requests.

Thank you!

Changes in v3:

- make SRAM mapping uncached
- make SWAP_STACK + brcmstb_pm_s3_finish a single asm volatile statement
- added Rob's Acked-by to first patch

Changes in v2:

- clarify the first patch's subject (Rob)
- removed patch #2 which was creating a bisectability problem (kbuild)
- added proper AFLAGS to get s2-arm.S to build properly (kbuild)
- improved MIPS power management binding document (Rob)
