Specification of the bindings for the parent MFD driver component of the Cirrus Logic Madera codec drivers. Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com> --- Changes since V1: - split out from main MFD patch - moved interrupt control binding descriptions into here - added description of the regulator child nodes - fixed the node name of the example - removed the MICBIAS from the example, these have been removed from the code Documentation/devicetree/bindings/mfd/madera.txt | 96 ++++++++++++++++++++++++ 1 file changed, 96 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/madera.txt
