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>

+BMP085/BMP18x digital pressure sensors
+
+Required properties:
+- compatible: bosch,bmp085
+
+Optional properties:
+- chip-id: configurable chip id for non-default chip revisions
+- temp-measurement-period: temperature measurement period (milliseconds)
+- default-oversampling: default oversampling value to be used at startup,
+ value range is 0-3 with rising sensitivity.
+- interrupt-parent: should be the phandle for the interrupt controller
+- interrupts: interrupt mapping for IRQ
+
+Example:
+
+pressure@77 {
+ compatible = "bosch,bmp085";
+ reg = <0x77>;
+ chip-id = <10>;
+ temp-measurement-period = <100>;
+ default-oversampling = <2>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <25 IRQ_TYPE_EDGE_RISING>;
+};
