[PATCH 1/2] sata_rcar: Adjust and document device tree bindings
From: Valentine Barshak <hidden>
Date: 2013-10-16 12:06:00
Also in:
linux-ide, linux-sh
Subsystem:
libata subsystem (serial and parallel ata drivers), open firmware and flattened device tree bindings, renesas r-car sata driver, the rest · Maintainers:
Damien Le Moal, Niklas Cassel, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Geert Uytterhoeven, Linus Torvalds
This deprecates the "rcar-sata" compatibility string and adds the "sata-r8a7779" which complies to the preferred <unit>-<soc> format for SH-Mobile devices. The DT bindings are documented.
