Subsystem: multifunction devices (mfd), open firmware and flattened device tree bindings, the rest · Maintainers: Lee Jones, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

Revision v2 of 6 in this series.

  6. v6 [diff vs current]
The BD71828 allows configuring the clk32kout pin mode to CMOS or
open-drain. Add device-tree property for specifying the preferred mode.

Changes from v1:
switched clk-mode property from string type to tristated one as
suggested by Rob.
