From 32d3b2d1ddeafe105ab6f738fba427242141194e Mon Sep 17 00:00:00 2001 From: Geert Uytterhoeven Date: Tue, 25 Feb 2014 11:21:08 +0100 Subject: spi: sh-msiof: Improve bindings Documentation: - Add missing "interrupt-parent", "#address-cells", "#size-cells", and "clocks" properties, - Add missing default values for "num-cs", "renesas,tx-fifo-size" and "renesas,rx-fifo-size", - Add a reference to the pinctrl documentation. Implementation: - As "num-cs" is marked optional, provide a sensible default.
