These changes are the raw update to linux-4.4.6-rt14. Kernel sources
are taken from kernel.org, and rt patch from the rt wiki download page. During the rebasing, the following patch collided: Force tick interrupt and get rid of softirq magic(I70131fb85). Collisions have been removed because its logic was found on the source already. Change-Id: I7f57a4081d9deaa0d9ccfc41a6c8daccdee3b769 Signed-off-by: José Pekkarinen <jose.pekkarinen@nokia.com>

+Device-Tree bindings for HDMI Transmitter
+
+HDMI Transmitter
+================
+
+The HDMI Transmitter is a Synopsys DesignWare HDMI 1.4 TX controller IP
+with accompanying PHY IP.
+
+Required properties:
+ - #address-cells : should be <1>
+ - #size-cells : should be <0>
+ - compatible : should be "fsl,imx6q-hdmi" or "fsl,imx6dl-hdmi".
+ - gpr : should be <&gpr>.
+ The phandle points to the iomuxc-gpr region containing the HDMI
+ multiplexer control register.
+ - clocks, clock-names : phandles to the HDMI iahb and isrf clocks, as described
+ in Documentation/devicetree/bindings/clock/clock-bindings.txt and
+ Documentation/devicetree/bindings/clock/imx6q-clock.txt.
+ - port@[0-4]: Up to four port nodes with endpoint definitions as defined in
+ Documentation/devicetree/bindings/media/video-interfaces.txt,
+ corresponding to the four inputs to the HDMI multiplexer.
+
+Optional properties:
+ - ddc-i2c-bus: phandle of an I2C controller used for DDC EDID probing
+
+example:
+
+ gpr: iomuxc-gpr@020e0000 {
+ /* ... */
+ };
+
+ hdmi: hdmi@0120000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "fsl,imx6q-hdmi";
+ reg = <0x00120000 0x9000>;
+ interrupts = <0 115 0x04>;
+ gpr = <&gpr>;
+ clocks = <&clks 123>, <&clks 124>;
+ clock-names = "iahb", "isfr";
+ ddc-i2c-bus = <&i2c2>;
+
+ port@0 {
+ reg = <0>;
+
+ hdmi_mux_0: endpoint {
+ remote-endpoint = <&ipu1_di0_hdmi>;
+ };
+ };
+
+ port@1 {
+ reg = <1>;
+
+ hdmi_mux_1: endpoint {
+ remote-endpoint = <&ipu1_di1_hdmi>;
+ };
+ };
+ };
