Merge tag 'imx-dt-4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into next/dt

Pull "i.MX device tree updates for 4.15" from Shawn Guo:

 - New board support: i.MX51 ZII RDU1, i.MX53 GE Healthcare PPD, i.MX6
   TX modules for MB7 from  Ka-Ro Electronics, i.MX6 Wandboard revd1
   variants, i.MX6 LWN DISPLAY5 board, Pistachio i.MX6Q board, i.MX6SX
   Vining-2000 board.
 - Use the 'vpcie-supply' property for PCIe device for boards
   imx6qdl-sabresd, imx6q-novena and imx6q-cm-fx6.
 - A series from Jagan Teki to update imx6qdl-icore board with audio,
   touch and CAN support.
 - Switch to nvmem for accessing OCOTP from tempmon for i.MX6SX and add
   tempmon support for i.MX6UL.
 - A bunch of patches from Lothar Waßmann updating Ka-Ro i.MX28, i.MX53
   and i.MX6 TX modules.
 - Fix DTC warnings in i.MX device trees, dropping leading zeros from
   unit address, correcting display nodes notation and display port
   names, fixing nodes with unit name and no reg property.
 - Other random device updates for various board support.

+* GE Healthcare USB Management Controller
+
+A device which handles data aquisition from compatible USB based peripherals.
+SPI is used for device management.
+
+Note: This device does not expose the peripherals as USB devices.
+
+Required properties:
+
+- compatible : Should be "ge,achc"
+
+Required SPI properties:
+
+- reg : Should be address of the device chip select within
+  the controller.
+
+- spi-max-frequency : Maximum SPI clocking speed of device in Hz, should be
+  1MHz for the GE ACHC.
+
+Example:
+
+spidev0: spi@0 {
+	compatible = "ge,achc";
+	reg = <0>;
+	spi-max-frequency = <1000000>;
+};
