Merge tag 'spi-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/misc

Pull spi updates from Mark Brown:
 "No framework work here, only a bunch of driver updates of varying
  sizes:

   - Factoring out of the core hardware support from the MXS MMC driver
     by Marek Vasut to allow the hardware to also be used for SPI.
   - Lots of error handling cleanups from Guenter Roeck
   - Removal of the existing Tegra driver which is quite comprehensively
     broken as detailed in the changelog for the removal.
   - DT suppport for the PL022 and GPIO drivers.
   - pinctrl support for OMAP and PL022."

Pulling from Mark Brown as Grant Likely is still busy moving.

+NXP SC18IS602/SCIS603
+
+Required properties:
+	- compatible : Should be one of
+		"nxp,sc18is602"
+		"nxp,sc18is602b"
+		"nxp,sc18is603"
+	- reg: I2C bus address
+
+Optional properties:
+	- clock-frequency : external oscillator clock frequency. If not
+	  specified, the SC18IS602 default frequency (7372000) will be used.
+
+The clock-frequency property is relevant and needed only if the chip has an
+external oscillator (SC18IS603).
+
+Example:
+
+	sc18is603@28 {
+		compatible = "nxp,sc18is603";
+		reg = <0x28>;
+		clock-frequency = <14744000>;
+	}
