+The platform_quirk element in the platform data was used to change the
+way the IRQ is triggered.  When set, the EDGE_IRQ quirk would change
+the irqflags used and treat edge trigger differently from the rest.
+
+Instead of hiding this irq flag setting behind the quirk, have the
+board files set the flags during initialization.  This will be more
+meaningful than driver-specific quirks when we switch to DT.
+
+Additionally, fix missing gpio_request() calls in the boarding files
+(so that setting the flags actually works).

+Add refclock and tcxoclock as clock providers in WiLink.  These clocks
+are not accesible outside the WiLink module, but they are registered
+in the clock framework anyway.  Only the WiLink chip consumes these
+clocks.
+
+In theory, the WiLink chip could be connected to external clocks
+instead of using these internal clocks, so make the clock consumer
+code generic enough.  If external clocks are used, then the internal
+clock device tree nodes are not necessary, but the external ones must
+be specified.

+The platform_quirk element in the platform data was used to change the
+way the IRQ is triggered.  When set, the EDGE_IRQ quirk would change
+the irqflags used and treat edge trigger differently from the rest.
+
+Instead of hiding this irq flag setting behind the quirk, have the
+board files set the flags during initialization.  This will be more
+meaningful than driver-specific quirks when we switch to DT.
+
+Additionally, fix missing gpio_request() calls in the boarding files
+(so that setting the flags actually works).

+Add refclock and tcxoclock as clock providers in WiLink.  These clocks
+are not accesible outside the WiLink module, but they are registered
+in the clock framework anyway.  Only the WiLink chip consumes these
+clocks.
+
+In theory, the WiLink chip could be connected to external clocks
+instead of using these internal clocks, so make the clock consumer
+code generic enough.  If external clocks are used, then the internal
+clock device tree nodes are not necessary, but the external ones must
+be specified.

++TI WiLink Wireless Modules Device Tree Bindings
++===============================================
++
++The WiLink modules provide wireless connectivity, such as WLAN,
++Bluetooth, FM and NFC.
++
++There are several different modules available, which can be grouped by
++their generation: WiLink6, WiLink7 and WiLink8.  WiLink4 is not
++currently supported with device tree.
++
++Currently, only the WLAN portion of the modules is supported with
++device tree.
++
++Required properties:
++--------------------
++
++- compatible: should be "ti,wilink6", "ti,wilink7" or "ti,wilink8"
++- interrupt-parent: the interrupt controller
++- interrupts: out-of-band WLAN interrupt
++	See the interrupt controller's bindings documentation for
++	detailed definition.
++
++Optional properties:
++--------------------
++
++- clocks: list of clocks needed by the chip as follows:
++
++  refclock: the internal WLAN reference clock frequency (required for
++	WiLink6 and WiLink7; not used for WiLink8).
++
++  tcxoclock: the internal WLAN TCXO clock frequency (required for
++	WiLink7 not used for WiLink6 and WiLink8).
++
++  The clocks must be defined and named accordingly.  For example:
++
++  clocks = <&refclock>
++  clock-names = "refclock";
++
++  refclock: refclock {
++		     compatible = "ti,wilink-clock";
++		     #clock-cells = <0>;
++		     clock-frequency = <38400000>;
++	};
++
++  Some modules that contain the WiLink chip provide clocks in the
++  module itself.  In this case, we define a "ti,wilink-clock" as shown
++  above.  But any other clock could in theory be used, so the proper
++  clock definition should be used.
++
++
++Example:
++--------
++
++Example definition that can be used in OMAP4 Panda:
++
++wlan {
++	compatible = "ti,wilink6";
++	interrupt-parent = <&gpio2>;
++	interrupts = <21 IRQ_TYPE_LEVEL_HIGH>;	/* gpio line 53 */
++	clocks = <&refclock>;
++	clock-names = "refclock";
++
++	refclock: refclock {
++		compatible = "ti,wilink-clock";
++		#clock-cells = <0>;
++		clock-frequency = <38400000>;
++	};
++};
