Changes in v9:
- Move to staging
- Previous patch series had a patch for file and the last commit would
add the Makefile bits to make it compile. But one file was dependent on
each other, so it doesn't make much sense to have a patch for each file
and it doesn't make it easier to review.
* capture.c
        - replace v4l2_{dgb,info,warn,err} by dev_*
* isp_stats.c
        - replace v4l2_{dgb,info,warn,err} by dev_*
        - remove LOG_ISR_EXE_TIME ifndef's
        - constify ops structs
        - s/strlcpy/strscpy
        - add missing mutex_destroy() calls in rkisp1_register_stats_vdev error path
* rkisp1:
        - replace v4l2_{dgb,info,warn,err} by dev_*
        - fix error returned in link_validate
        - remove s_power() callback
        - add regwrite/regread wrappers
        - add macros RKISP1_DEF_SRC_PAD_FMT/RKISP1_DEF_SINK_PAD_FMT
        - several minor cleanups
        - s/RKISP1_ISP_PAD_SINK([^_])/RKISP1_ISP_PAD_SINK_VIDEO\1/
        - merge tables rkisp1_isp_input_formats and rkisp1_isp_output_formats
        - in_fmt and out_fmt as pointers
        - simply struct rkisp1_isp_subdev to work correctly with try format
        - fix crop/fmt propagation
* dev.h / dev.c / regs.c / regs.h / common.h
        - replace v4l2_{dgb,info,warn,err} by dev_*
        - s/pr_info/dev_dbg
        - s/int size/unsigned int size
        - remove module param rkisp1_debug
        - coding style fixes
        - fix error in subdev_notifier_bound, check dphy before assigning to sensor->dphy
        - remove subdevs fixed size array from rkisp1_pipeline
        - remove sensors list, as it can be identified from the media topology
        - Kconfig: add COMPILE_TEST in the dependency
        - use v4l2_pipeline_pm_use and remove _isp_pipeline_s_power() and _subdev_set_power()
        - remove struct rkisp1_pipeline and retrieve pipeline information from the media framework
        - remove remaining rk3288 code
        - cache pixel rate control in sctruct sensor_async_subdev
        - remove enum rkisp1_sd_type

+Rockchip SoC Image Signal Processing unit v1
+--------------------------------------------
+
+Rockchip ISP1 is the Camera interface for the Rockchip series of SoCs
+which contains image processing, scaling, and compression funcitons.
+
+Required properties:
+- compatible: value should be one of the following
+	"rockchip,rk3288-cif-isp";
+	"rockchip,rk3399-cif-isp";
+- reg : offset and length of the register set for the device.
+- interrupts: should contain ISP interrupt.
+- clocks: phandle to the required clocks.
+- clock-names: required clock name.
+- iommus: required a iommu node.
+- phys: the phandle for the PHY port
+- phy-names: must contain "dphy"
+
+port node
+---------
+
+The device node should contain one 'ports' child node, with children 'port'
+with child 'endpoint'.
+nodes, according to the bindings defined in Documentation/devicetree/bindings/
+media/video-interfaces.txt.
+
+- endpoint(mipi):
+	- remote-endpoint: Connecting to Rockchip MIPI-DPHY,
+		which is defined in rockchip-mipi-dphy.txt.
+
+The port node must contain at least one endpoint, either parallel or mipi.
+It could have multiple endpoints, but please note the hardware don't support
+two sensors work at a time, they are supposed to work asynchronously.
+
+Device node example
+-------------------
+
+	isp0: isp0@ff910000 {
+		compatible = "rockchip,rk3399-cif-isp";

+Rockchip SoC MIPI RX D-PHY
+--------------------------
+
+Required properties:
+- compatible: value should be one of the following
+	"rockchip,rk3288-mipi-dphy"
+	"rockchip,rk3399-mipi-dphy"
+- clocks : list of clock specifiers, corresponding to entries in
+	clock-names property;
+- clock-names: required clock name.
+- #phy-cells: Number of cells in a PHY specifier; Should be 0.
+
+MIPI RX D-PHY use registers in "general register files", it
+should be a child of the GRF.
+
+Optional properties:
+- reg: offset and length of the register set for the device.
+- rockchip,grf: MIPI TX1RX1 D-PHY not only has its own register but also
+		the GRF, so it is only necessary for MIPI TX1RX1 D-PHY.
+
+Device node example
+-------------------

+	compatible = "rockchip,rk3399-grf", "syscon", "simple-mfd";
