+* Devantech SRF04 ultrasonic range finder
+  Bit-banging driver using two GPIOs
+
+Required properties:
+ - compatible:	Should be "devantech,srf04"
+
+ - trig-gpios:	Definition of the GPIO for the triggering (output)
+		This GPIO is set for about 10 us by the driver to tell the
+		device it should initiate the measurement cycle.
+
+ - echo-gpios:	Definition of the GPIO for the echo (input)
+		This GPIO is set by the device as soon as an ultrasonic
+		burst is sent out and reset when the first echo is
+		received.
+		Thus this GPIO is set while the ultrasonic waves are doing
+		one round trip.
+		It needs to be an GPIO which is able to deliver an
+		interrupt because the time between two interrupts is
+		measured in the driver.
+		See Documentation/devicetree/bindings/gpio/gpio.txt for
+		information on how to specify a consumer gpio.
+
+Example:
+srf04@0 {
+	compatible = "devantech,srf04";
+	trig-gpios = <&gpio1 15 GPIO_ACTIVE_HIGH>;
+	echo-gpios = <&gpio2  6 GPIO_ACTIVE_HIGH>;

+ * every X seconds).
+ * One would be tempted to disable the IP on the hardware side rather than
+ * disabling interrupts to save some power but that resets the internal clock of
+ * the IP, resulting in having to wait X seconds every time we want to read the
+ * value of the thermal sensor.
+ * This is also the reason of using autosuspend in pm_runtime. If there was no
+ * autosuspend, the thermal sensor would need X seconds after every
+ * pm_runtime_get_sync to get a value from the ADC. The autosuspend allows the
+ * thermal sensor to be requested again in a certain time span before it gets
+ * shutdown for not being used.

- * The lowmemorykiller driver lets user-space specify a set of memory thresholds
- * where processes with a range of oom_score_adj values will get killed. Specify
- * the minimum oom_score_adj values in
- * /sys/module/lowmemorykiller/parameters/adj and the number of free pages in
- * /sys/module/lowmemorykiller/parameters/minfree. Both files take a comma
- * separated list of numbers in ascending order.
- *
- * For example, write "0,8" to /sys/module/lowmemorykiller/parameters/adj and
- * "1024,4096" to /sys/module/lowmemorykiller/parameters/minfree to kill
- * processes with a oom_score_adj value of 8 or higher when the free memory
- * drops below 4096 pages and kill processes with a oom_score_adj value of 0 or
- * higher when the free memory drops below 1024 pages.
- *
- * The driver considers memory used for caches to be free, but if a large
- * percentage of the cached memory is locked this can be very inaccurate
- * and processes may not get killed until the normal oom killer is triggered.

+Introduction
+------------
+
+A DPAA2 DPIO (Data Path I/O) is a hardware object that provides
+interfaces to enqueue and dequeue frames to/from network interfaces
+and other accelerators.  A DPIO also provides hardware buffer
+pool management for network interfaces.
+
+This document provides an overview the Linux DPIO driver, its
+subcomponents, and its APIs.
+
+See Documentation/dpaa2/overview.txt for a general overview of DPAA2
+and the general DPAA2 driver architecture in Linux.
+
+Driver Overview
+---------------
+
+The DPIO driver is bound to DPIO objects discovered on the fsl-mc bus and
+provides services that:
+  A) allow other drivers, such as the Ethernet driver, to enqueue and dequeue
+     frames for their respective objects
+  B) allow drivers to register callbacks for data availability notifications
+     when data becomes available on a queue or channel
+  C) allow drivers to manage hardware buffer pools
+
+The Linux DPIO driver consists of 3 primary components--
+   DPIO object driver-- fsl-mc driver that manages the DPIO object
+   DPIO service-- provides APIs to other Linux drivers for services
+   QBman portal interface-- sends portal commands, gets responses
+
+          fsl-mc          other
+           bus           drivers

+
+ ============================================================================
+
+
+DPIO Object Driver (dpio-driver.c)
+----------------------------------
+
+   The dpio-driver component registers with the fsl-mc bus to handle objects of
+   type "dpio".  The implementation of probe() handles basic initialization
+   of the DPIO including mapping of the DPIO regions (the QBman SW portal)
+   and initializing interrupts and registering irq handlers.  The dpio-driver
+   registers the probed DPIO with dpio-service.
+
+DPIO service  (dpio-service.c, dpaa2-io.h)
+------------------------------------------
+
+   The dpio service component provides queuing, notification, and buffers
+   management services to DPAA2 drivers, such as the Ethernet driver.  A system
+   will typically allocate 1 DPIO object per CPU to allow queuing operations
+   to happen simultaneously across all CPUs.
+
+   Notification handling
+      dpaa2_io_service_register()
+      dpaa2_io_service_deregister()
+      dpaa2_io_service_rearm()
+
+   Queuing
+      dpaa2_io_service_pull_fq()
+      dpaa2_io_service_pull_channel()
+      dpaa2_io_service_enqueue_fq()
+      dpaa2_io_service_enqueue_qd()
+      dpaa2_io_store_create()
+      dpaa2_io_store_destroy()
+      dpaa2_io_store_next()
+
+   Buffer pool management
+      dpaa2_io_service_release()
+      dpaa2_io_service_acquire()
+
+QBman portal interface (qbman-portal.c)
+---------------------------------------
+
+   The qbman-portal component provides APIs to do the low level hardware
+   bit twiddling for operations such as:
+      -initializing Qman software portals
+      -building and sending portal commands
+      -portal interrupt configuration and processing
+
+   The qbman-portal APIs are not public to other drivers, and are
+   only used by dpio-service.
+
+Other (dpaa2-fd.h, dpaa2-global.h)
+----------------------------------
+
+   Frame descriptor and scatter-gather definitions and the APIs used to
+   manipulate them are defined in dpaa2-fd.h.
+
+   Dequeue result struct and parsing APIs are defined in dpaa2-global.h.

+1. A single AtomISP driver needs to be implemented to support both BYT and
+   CHT platforms. The current driver is a mechanical and hand combined merge
+   of the two using an ifdef ISP2401 to select the CHT version, which at the
+   moment is not enabled. Eventually this should become a runtime if check,
+   but there are some quite tricky things that need sorting out before that
+   will be possible.
+
+2. The file structure needs to get tidied up to resemble a normal Linux
+   driver.
+
+3. Lots of the midlayer glue. unused code and abstraction needs removing.
+
+3. The sensor drivers read MIPI settings from EFI variables or default to the
+   settings hard-coded in the platform data file for different platforms.
+   This isn't ideal but may be hard to improve as this is how existing
+   platforms work.
+
+4. The sensor drivers use the regulator framework API. In the ideal world it
+   would be using ACPI but that's not how the existing devices work.
+
+5. The AtomISP driver includes some special IOCTLS (ATOMISP_IOC_XXXX_XXXX)
+   that may need some cleaning up.
+
+6. Correct Coding Style. Please don't send coding style patches for this
+   driver until the other work is done.
+
+7. The ISP code depends on the exact FW version. The version defined in
+   BYT: 
+   drivers/staging/media/atomisp/pci/atomisp2/css2400/sh_css_firmware.c
+   static const char *release_version = STR(irci_stable_candrpv_0415_20150521_0458);
+   CHT:
+   drivers/staging/media/atomisp/pci/atomisp2/css/sh_css_firmware.c
+   static const char *release_version = STR(irci_ecr-master_20150911_0724);
+
+   At some point we may need to round up a few driver versions and see if
+   there are any specific things that can be done to fold in support for
+   multiple firmware versions.
+
+
+Limitations:
+
+1. Currently the patch only support some camera sensors
+   gc2235/gc0310/0v2680/ov2722/ov5693/mt9m114...
+
+2. To test the patches, you also need the ISP firmware
+
+   for BYT:/lib/firmware/shisp_2400b0_v21.bin
+   for CHT:/lib/firmware/shisp_2401a0_v21.bin
+
+   The firmware files will usually be found in /etc/firmware on an Android
+   device but can also be extracted from the upgrade kit if you've managed
+   to lose them somehow.
+
+3. Without a 3A libary the capture behaviour is not very good. To take a good
+   picture, you need tune ISP parameters by IOCTL functions or use a 3A libary
+   such as libxcam.
+
+4. The driver is intended to drive the PCI exposed versions of the device.
+   It will not detect those devices enumerated via ACPI as a field of the
+   i915 GPU driver.
+
+5. The driver supports only v2 of the IPU/Camera. It will not work with the
+   versions of the hardware in other SoCs.

+		 *	cx = sensor_data_origin_bqs_on_sctbl.x + W/2
+		 *	cy = sensor_data_origin_bqs_on_sctbl.y + H/2
+		 *
+		 *    CSS decides the shading table size and the sensor data position
+		 *    so that the (cx, cy) satisfies this condition.
+		 *	mod(cx, bqs_per_grid_cell) = 0
+		 *	mod(cy, bqs_per_grid_cell) = 0
+		 *
+		 *  ****** How to change the sensor data size by processes in the driver and ISP ******
+		 *
+		 *    1. sensor data size: Physical sensor size
+		 *			   (The struct ia_css_shading_info does not have this information.)
+		 *    2. process:          Driver applies the sensor cropping/binning/scaling to physical sensor size.

+ * Padding:
+ * The area that the ISP operates on can include padding both on the left
+ * and the right. We need to padd the shading table such that the shading
+ * values end up on the correct pixel values. This means we must padd the
+ * shading table to match the ISP padding.
+ * We can have 5 cases:
+ * 1. All 4 points fall in the left padding.
+ * 2. The left 2 points fall in the left padding.
+ * 3. All 4 points fall in the cropped (target) region.
+ * 4. The right 2 points fall in the right padding.
+ * 5. All 4 points fall in the right padding.
+ * Cases 1 and 5 are easy to handle: we simply use the
+ * value 1 in the shading table.
+ * Cases 2 and 4 require interpolation that takes into
+ * account how far into the padding area the pixels
+ * fall. We extrapolate the shading table into the
