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>

+Optional nodes:
+- DSS Submodules: HDMI
+- Video port for DPI output
+
+DPI Endpoint required properties:
+- data-lines: number of lines used

+HDMI
+----
+
+Required properties:
+- compatible: "ti,dra7-hdmi"
+- reg: addresses and lengths of the register spaces for 'wp', 'pll', 'phy',
