Merge branch 'drm-armada-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into drm-next

Merge armada changes, I've confirmed the componenet changes are same as in Greg's tree.
* 'drm-armada-devel' of git://ftp.arm.linux.org.uk/~rmk/linux-arm:
  drm/armada: register crtc with port
  drm/armada: permit CRTCs to be registered as separate devices
  dt-bindings: add Marvell Dove LCD controller documentation
  drm/armada: update Armada 510 (Dove) to use "ext_ref_clk1" as the clock
  drm/armada: convert to componentized support
  drm: add of_graph endpoint helper to find possible CRTCs
  component: fix bug with legacy API
  drm/armada: make variant a CRTC thing
  drm/armada: move variant initialisation to CRTC init
  drm/armada: use number of CRTCs registered
  drm/armada: move IRQ handling into CRTC
  component: add support for component match array
  component: ignore multiple additions of the same component
  component: fix missed cleanup in case of devres failure

+Device Tree bindings for Armada DRM CRTC driver
+
+Required properties:
+ - compatible: value should be "marvell,dove-lcd".
+ - reg: base address and size of the LCD controller
+ - interrupts: single interrupt number for the LCD controller
+ - port: video output port with endpoints, as described by graph.txt
+
+Optional properties:
+
+ - clocks: as described by clock-bindings.txt
+ - clock-names: as described by clock-bindings.txt
+	"axiclk" - axi bus clock for pixel clock
+	"plldivider" - pll divider clock for pixel clock
+	"ext_ref_clk0" - external clock 0 for pixel clock
+	"ext_ref_clk1" - external clock 1 for pixel clock
+
+Note: all clocks are optional but at least one must be specified.
+Further clocks may be added in the future according to requirements of
+different SoCs.
+
+Example:
+
+	lcd0: lcd-controller@820000 {
+		compatible = "marvell,dove-lcd";
+		reg = <0x820000 0x1000>;
+		interrupts = <47>;
+		clocks = <&si5351 0>;
+		clock-names = "ext_ref_clk_1";
+	};
