Subject: [PATCH v2 3/5] devicetree: create a separate binding description for sata_highbank
Date: Fri, 2 Aug 2013 11:28:36 -0500 [thread overview]
Message-ID: <1375460918-4661-3-git-send-email-mark.langsdorf@calxeda.com> (raw)
In-Reply-To: <1375460918-4661-1-git-send-email-mark.langsdorf@calxeda.com>
The Calxeda sata_highbank driver has been adding its descriptions to the
ahci driver. Separate them properly.

+* Calxeda AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+The Calxeda SATA controller mostly conforms to the AHCI interface
+with some special extensions to add functionality.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains "calxeda,hb-ahci"
+- interrupts : <interrupt mapping for SATA IRQ>
+- reg : <registers mapping>
+
+Optional properties:
+- dma-coherent : Present if dma operations are coherent
+- calxeda,port-phys: phandle-combophy and lane assignment, which maps each
+ SATA port to a combophy and a lane within that
+ combophy
+- calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
+ which indicates that the driver supports SGPIO
+ indicator lights using the indicated GPIOs
+- calxeda,led-order : a u32 array that map port numbers to offsets within the
+ SGPIO bitstream.
+
+Example:
+ sata@ffe08000 {
+ compatible = "calxeda,hb-ahci";
+ reg = <0xffe08000 0x1000>;
+ interrupts = <115>;
+ calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
+ &combophy0 2 &combophy0 3>;
