[PATCH v3 2/5] Documentation: devicetree: add Broadcom SATA PHY binding
From: computersforpeace@gmail.com (Brian Norris)
Date: 2015-05-12 23:29:32
Also in:
linux-devicetree, linux-ide, lkml
Subsystem:
generic phy framework, open firmware and flattened device tree bindings, the rest · Maintainers:
Vinod Koul, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
For 28nm STB chips, based on BCM7445.

v3: no change
v2:
- make each subnode into a provider, so we can use direct phandle references
to them
- drop the 'port-ctrl' register range, since this was shared with the SATA
node
