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>

+NXP LPC1788 real-time clock
+
+The LPC1788 RTC provides calendar and clock functionality
+together with periodic tick and alarm interrupt support.
+
+Required properties:
+- compatible : must contain "nxp,lpc1788-rtc"
+- reg : Specifies base physical address and size of the registers.
+- interrupts : A single interrupt specifier.
+- clocks : Must contain clock specifiers for rtc and register clock
+- clock-names : Must contain "rtc" and "reg"
+ See ../clocks/clock-bindings.txt for details.
+
+Example:
+rtc: rtc@40046000 {
+ compatible = "nxp,lpc1788-rtc";
+ reg = <0x40046000 0x1000>;
+ interrupts = <47>;
+ clocks = <&creg_clk 0>, <&ccu1 CLK_CPU_BUS>;
+ clock-names = "rtc", "reg";
+};
