Based on work by Kazuya Mizuguchi and others. Signed-off-by: Simon Horman Acked-by: Geert Uytterhoeven --- v2 * First post; broken out of a driver update patch * As discussed with Geert Uytterhoeven and Sergei Shtylyov - Binding: Make all interrupts mandatory as named-interrupts of the form ch%u v3 * A suggested by Geert Uytterhoeven - Reword description of interrupts and interrupt-names to make things clearer. It is now based to some extent on spi-rspi.txt and renesas,usb-dmac.txt. * As suggested by Sergei Shtylyov - Drop phy-reset-gpio from example * Added power-domains to example v4 * A suggested by Geert Uytterhoeven - grammar fix for interrupt-names description * Add ack --- .../devicetree/bindings/net/renesas,ravb.txt | 69 +++++++++++++++++++--- 1 file changed, 62 insertions(+), 7 deletions(-) diff --git a/Documentation/devicetree/bindings/net/renesas,ravb.txt b/Documentation/devicetree/bindings/net/renesas,ravb.txt index 1fd8831437bf..b486f3f5f6a3 100644 --- a/Documentation/devicetree/bindings/net/renesas,ravb.txt +++ b/Documentation/devicetree/bindings/net/renesas,ravb.txt @@ -6,8 +6,12 @@ interface contains.
