[PATCH v4 2/3] wlcore/wl12xx: spi: add device tree support

[Uri Mashiach]

Add DT support for the wl1271 SPI WiFi.

Add documentation file for the wl1271 SPI WiFi.

Signed-off-by: Uri Mashiach <uri.mashiach@compulab.co.il>
Acked-by: Rob Herring <robh@kernel.org>
---
v1 -> v2: update interrupt documentation.
          replace interrupts and interrupt-parent with interrupts-extended.
	  IRQ parameters retrieved from spi_device instead of DT.
	  remove redundant #ifdef CONFIG_OF
v2 -> v3: Add MODULE_DEVICE_TABLE.
          Remove #ifdef CONFIG_OF.
	  Make the Kconfig symbol to depend on OF.
	  Replace irqd_get_trigger_type() with irq_get_trigger_type().
v3 -> v4: replace interrupts-extended with interrupts and interrupt-parent. (revert v2 modification).
          According to Rob Herring and Documentation/devicetree/bindings/interrupt-controller/interrupts.txt,
	  interrupts-extended should only be used when a device has multiple interrupt parents.

+The wl1271 chip can be connected via SPI or via SDIO. This

+- reg :                 Chip select address of device
+- spi-max-frequency :   Maximum SPI clocking speed of device in Hz
+- ref-clock-frequency : Reference clock frequency
+- interrupt-parent, interrupts :
+                        Should contain parameters for 1 interrupt line.
+                        Interrupt parameters: parent, line number, type.
+- vwlan-supply :        Point the node of the regulator that powers/enable the wl1271 chip

[PATCH] ARM: dts: N950: Add wlan support

[Sebastian Reichel]

Add support for the wl1271 wlan chip. As far as I can see N9 uses the
same chip with the same enable and irq gpio, but they use the mmc
interface instead of the spi interface.

Hi,

I got working Wifi on Nokia N950 with this patch and the following
patches from Uri Mashiach (using 4.4-rc8 as base):

 * wlcore/wl12xx: spi: add power operation function
 * wlcore/wl12xx: spi: add device tree support
 * wlcore/wl12xx: spi: fix oops on firmware load

Right. It will hit the mainline during this merge window through Tony's and
arm-soc trees.

Do you think it will be sensible if you take 1/3 and 2/3 patches and Tony
will take the 3/3 (there is no code dependency between first two and the last one),
or we can just wait till arm-soc hits the mainline, so you will have the
needed code?

Yeah I'll pick the dts changes separately after the merge window as
there is no dependency to the driver changes.

I guess it is semantics, but the merge window is open right now so you 
probably mean to say after the merge window closes, ie. when 4.5-rc1 is 
ready.
