Subject: [PATCH 06/10] spi: sh-msiof: Improve binding documentation
Date: Thu, 20 Feb 2014 15:43:05 +0100 [thread overview]
Message-ID: <1392907389-21798-7-git-send-email-geert@linux-m68k.org> (raw)
In-Reply-To: <1392907389-21798-1-git-send-email-geert@linux-m68k.org>
From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>
- Add missing "interrupt-parent", "#address-cells", "#size-cells", and
"clocks" properties,
- Add missing default values for "renesas,tx-fifo-size" and
"renesas,rx-fifo-size",
- Add a reference to the pinctrl documentation.

Renesas MSIOF spi controller
Required properties:
-- compatible : "renesas,sh-msiof" for SuperH or
- "renesas,sh-mobile-msiof" for SH Mobile series
-- reg : Offset and length of the register set for the device
-- interrupts : interrupt line used by MSIOF
+- compatible : "renesas,sh-msiof" for SuperH, or
+ "renesas,sh-mobile-msiof" for SH Mobile series.
+- reg : Offset and length of the register set for the device
+- interrupt-parent : The phandle for the interrupt controller that
+ services interrupts for this device
+- interrupts : Interrupt specifier
+- #address-cells : Must be <1>
+- #size-cells : Must be <0>
Optional properties:
-- num-cs : total number of chip-selects
-- renesas,tx-fifo-size : Overrides the default tx fifo size given in words
-- renesas,rx-fifo-size : Overrides the default rx fifo size given in words
+- clocks : Must contain a reference to the functional clock.
+- num-cs : Total number of chip-selects
+- renesas,tx-fifo-size : Overrides the default tx fifo size given in words
+ (default is 64)
+- renesas,rx-fifo-size : Overrides the default rx fifo size given in words
+ (default is 64)
+
+Pinctrl properties might be needed, too. See
+Documentation/devicetree/bindings/pinctrl/renesas,*.
