Subject: [PATCH v3 1/3] spi: hs-spi: Improve bindings
Date: Tue, 25 Feb 2014 11:34:52 +0100 [thread overview]
Message-ID: <1393324492-3527-1-git-send-email-geert@linux-m68k.org> (raw)
From: Geert Uytterhoeven <geert+renesas@linux-m68k.org>
- Add future-proof "renesas,hspi-<soctype>" compatible values,
- Add missing "interrupt-parent", "#address-cells", and "#size-cells"
properties,
- Add reference to pinctrl documentation,
- Add example bindings.
Signed-off-by: Geert Uytterhoeven <geert+renesas@linux-m68k.org>

v3:
- Split in two patches: bindings and dtsi updates
v2:
- Add Tested-by
- List full example compatible properties with soctypes instead of just
the soctypes, so checkpatch can validate DTSes.

Renesas HSPI.
Required properties:
-- compatible : "renesas,hspi"
-- reg : Offset and length of the register set for the device
-- interrupts : interrupt line used by HSPI
+- compatible : "renesas,hspi-<soctype>", "renesas,hspi" as fallback.
+ Examples with soctypes are:
+ - "renesas,hspi-r8a7778" (R-Car M1)
+ - "renesas,hspi-r8a7779" (R-Car H1)
+- 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>
+
+Pinctrl properties might be needed, too. See
+Documentation/devicetree/bindings/pinctrl/renesas,*.
+
+Example:
+
+ hspi0: spi@fffc7000 {
+ compatible = "renesas,hspi-r8a7778", "renesas,hspi";
+ reg = <0xfffc7000 0x18>;
+ interrupt-parent = <&gic>;
+ interrupts = <0 63 IRQ_TYPE_LEVEL_HIGH>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ status = "disabled";
+ };
