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>

-MIPI DSI (Display Serial Interface) busses
-==========================================
-
-The MIPI Display Serial Interface specifies a serial bus and a protocol for
-communication between a host and up to four peripherals. This document will
-define the syntax used to represent a DSI bus in a device tree.
-
-This document describes DSI bus-specific properties only or defines existing
-standard properties in the context of the DSI bus.
-
-Each DSI host provides a DSI bus. The DSI host controller's node contains a
-set of properties that characterize the bus. Child nodes describe individual
-peripherals on that bus.
-
-The following assumes that only a single peripheral is connected to a DSI
-host. Experience shows that this is true for the large majority of setups.
-
-DSI host
---------
-
-In addition to the standard properties and those defined by the parent bus of
-a DSI host, the following properties apply to a node representing a DSI host.
-
-Required properties:
-- #address-cells: The number of cells required to represent an address on the
- bus. DSI peripherals are addressed using a 2-bit virtual channel number, so
- a maximum of 4 devices can be addressed on a single bus. Hence the value of
- this property should be 1.
-- #size-cells: Should be 0. There are cases where it makes sense to use a
- different value here. See below.
-
-DSI peripheral
---------------
-
-Peripherals are represented as child nodes of the DSI host's node. Properties
-described here apply to all DSI peripherals, but individual bindings may want
-to define additional, device-specific properties.
-
-Required properties:
-- reg: The virtual channel number of a DSI peripheral. Must be in the range
- from 0 to 3.
-
-Some DSI peripherals respond to more than a single virtual channel. In that
-case two alternative representations can be chosen:
-- The reg property can take multiple entries, one for each virtual channel
- that the peripheral responds to.
-- If the virtual channels that a peripheral responds to are consecutive, the
- #size-cells can be set to 1. The first cell of each entry in the reg
- property is the number of the first virtual channel and the second cell is
- the number of consecutive virtual channels.
-
-Example
--------
-
- dsi-host {
- ...
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- /* peripheral responds to virtual channel 0 */
- peripheral@0 {
- compatible = "...";
- reg = <0>;
- };
-
- ...
- };
-
- dsi-host {
- ...
-
- #address-cells = <1>;
- #size-cells = <0>;
-
- /* peripheral responds to virtual channels 0 and 2 */
- peripheral@0 {
- compatible = "...";
- reg = <0, 2>;
- };
-
- ...
- };
-
- dsi-host {
- ...
-
- #address-cells = <1>;
- #size-cells = <1>;
-
- /* peripheral responds to virtual channels 1, 2 and 3 */
- peripheral@1 {
- compatible = "...";
- reg = <1 3>;
- };
-
- ...
- };

-NVIDIA Tegra MIPI pad calibration controller
-
-Required properties:
-- compatible: "nvidia,tegra<chip>-mipi"
-- reg: Physical base address and length of the controller's registers.
-- clocks: Must contain an entry for each entry in clock-names.
- See ../clocks/clock-bindings.txt for details.
-- clock-names: Must include the following entries:
- - mipi-cal
-- #nvidia,mipi-calibrate-cells: Should be 1. The cell is a bitmask of the pads
- that need to be calibrated for a given device.
-
-User nodes need to contain an nvidia,mipi-calibrate property that has a
-phandle to refer to the calibration controller node and a bitmask of the pads
-that need to be calibrated.
-
-Example:
-
- mipi: mipi@700e3000 {
- compatible = "nvidia,tegra114-mipi";
- reg = <0x700e3000 0x100>;
- clocks = <&tegra_car TEGRA114_CLK_MIPI_CAL>;
- clock-names = "mipi-cal";
- #nvidia,mipi-calibrate-cells = <1>;
