Subject: [PATCH v3 0/2] reset: Add Broadcom STB RESCAL reset controller

Hi Philipp,

This patch series adds support for the BCM7216 RESCAL reset controller
which is necessary to initialize SATA and PCIe0/1 on that chip.

Please let us know if you have any comments. Thanks!

Changes in v3:

- indented "base" variable with a space
- return ret directly out of readl_poll_timeout()
- removed additional register read after write, not necessary
- removed call to platform_set_drvdata, unnecessary either
- corrected Jim's email in Signed-off-by in patch #2

Changes in v2:

- binding document is in YAML format per Rob's suggestion
- indented bit definitions the same way for all definitions
- moved reset logic to the .reset() callback
- removed the XOR operation which is not necessary after clarifying with
  Jim that this was not necessary
- use readl_poll_timeout()
