Merge tag 'staging-4.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging
Pull staging and IIO driver updates from Greg KH: "Here is the big Staging and IIO driver update for 4.8-rc1. We ended up adding more code than removing, again, but it's not all that bad. Lots of cleanups all over the staging tree, and new IIO drivers, full details in the shortlog.

+ * About determining pressure scaling factors
+ * ------------------------------------------
+ *
+ * Datasheets specify typical pressure sensitivity so that pressure is computed
+ * according to the following equation :
+ * pressure[mBar] = raw / sensitivity
+ * where :
+ * raw the 24 bits long raw sampled pressure
+ * sensitivity a scaling factor specified by the datasheet in LSB/mBar
+ *
+ * IIO ABI expects pressure to be expressed as kPascal, hence pressure should be
+ * computed according to :
+ * pressure[kPascal] = pressure[mBar] / 10
+ * = raw / (sensitivity * 10) (1)
+ *
+ * Finally, st_press_read_raw() returns pressure scaling factor as an
+ * IIO_VAL_INT_PLUS_NANO with a zero integral part and "gain" as decimal part.
+ * Therefore, from (1), "gain" becomes :
+ * gain = 10^9 / (sensitivity * 10)
+ * = 10^8 / sensitivity
+ *
+ * About determining temperature scaling factors and offsets
+ * ---------------------------------------------------------
+ *
+ * Datasheets specify typical temperature sensitivity and offset so that
+ * temperature is computed according to the following equation :
+ * temp[Celsius] = offset[Celsius] + (raw / sensitivity)
+ * where :
+ * raw the 16 bits long raw sampled temperature
+ * offset a constant specified by the datasheet in degree Celsius
+ * (sometimes zero)
+ * sensitivity a scaling factor specified by the datasheet in LSB/Celsius
+ *
+ * IIO ABI expects temperature to be expressed as milli degree Celsius such as
+ * user space should compute temperature according to :
+ * temp[mCelsius] = temp[Celsius] * 10^3
+ * = (offset[Celsius] + (raw / sensitivity)) * 10^3
+ * = ((offset[Celsius] * sensitivity) + raw) *
+ * (10^3 / sensitivity) (2)
+ *
+ * IIO ABI expects user space to apply offset and scaling factors to raw samples
+ * according to :
+ * temp[mCelsius] = (OFFSET + raw) * SCALE
+ * where :
+ * OFFSET an arbitrary constant exposed by device
+ * SCALE an arbitrary scaling factor exposed by device
+ *
+ * Matching OFFSET and SCALE with members of (2) gives :
+ * OFFSET = offset[Celsius] * sensitivity (3)
+ * SCALE = 10^3 / sensitivity (4)
+ *
+ * st_press_read_raw() returns temperature scaling factor as an
+ * IIO_VAL_FRACTIONAL with a 10^3 numerator and "gain2" as denominator.
+ * Therefore, from (3), "gain2" becomes :
+ * gain2 = sensitivity
+ *
+ * When declared within channel, i.e. for a non zero specified offset,
+ * st_press_read_raw() will return the latter as an IIO_VAL_FRACTIONAL such as :
+ * numerator = OFFSET * 10^3
+ * denominator = 10^3
+ * giving from (4):
+ * numerator = offset[Celsius] * 10^3 * sensitivity

+ * Driver: addi_apci_1564
+ * Description: ADDI-DATA APCI-1564 Digital I/O board
+ * Devices: [ADDI-DATA] APCI-1564 (addi_apci_1564)
+ * Author: H Hartley Sweeten <hsweeten@visionengravers.com>
+ * Updated: Thu, 02 Jun 2016 13:12:46 -0700
+ * Status: untested
+ *
+ * Configuration Options: not applicable, uses comedi PCI auto config
+ *
+ * This board has the following features:
+ * - 32 optically isolated digital inputs (24V), 16 of which can
+ * generate change-of-state (COS) interrupts (channels 4 to 19)
+ * - 32 optically isolated digital outputs (10V to 36V)
+ * - 1 8-bit watchdog for resetting the outputs
+ * - 1 12-bit timer
+ * - 3 32-bit counters
+ * - 2 diagnostic inputs
+ *
+ * The COS, timer, and counter subdevices all use the dev->read_subdev to
+ * return the interrupt status. The sample data is updated and returned when
+ * any of these subdevices generate an interrupt. The sample data format is:
+ *
+ * Bit Description
+ * ----- ------------------------------------------
+ * 31 COS interrupt
+ * 30 timer interrupt
+ * 29 counter 2 interrupt
+ * 28 counter 1 interrupt
+ * 27 counter 0 interrupt
+ * 26:20 not used
+ * 19:4 COS digital input state (channels 19 to 4)
+ * 3:0 not used
+ *
+ * The COS interrupts must be configured using an INSN_CONFIG_DIGITAL_TRIG
+ * instruction before they can be enabled by an async command. The COS
+ * interrupts will stay active until canceled.
+ *
+ * The timer subdevice does not use an async command. All control is handled
+ * by the (*insn_config).
+ *
+ * FIXME: The format of the ADDI_TCW_TIMEBASE_REG is not descibed in the
+ * datasheet I have. The INSN_CONFIG_SET_CLOCK_SRC currently just writes
+ * the raw data[1] to this register along with the raw data[2] value to the
+ * ADDI_TCW_RELOAD_REG. If anyone tests this and can determine the actual

-Driver: das16m1
-Description: CIO-DAS16/M1
-Author: Frank Mori Hess <fmhess@users.sourceforge.net>
-Devices: [Measurement Computing] CIO-DAS16/M1 (das16m1)
-Status: works
-
-This driver supports a single board - the CIO-DAS16/M1.
-As far as I know, there are no other boards that have
-the same register layout. Even the CIO-DAS16/M1/16 is
-significantly different.
-
-I was _barely_ able to reach the full 1 MHz capability
-of this board, using a hard real-time interrupt
-(set the TRIG_RT flag in your struct comedi_cmd and use
-rtlinux or RTAI). The board can't do dma, so the bottleneck is
-pulling the data across the ISA bus. I timed the interrupt
-handler, and it took my computer ~470 microseconds to pull 512
-samples from the board. So at 1 Mhz sampling rate,
-expect your CPU to be spending almost all of its
-time in the interrupt handler.
-
-This board has some unusual restrictions for its channel/gain list. If the
-list has 2 or more channels in it, then two conditions must be satisfied:
-(1) - even/odd channels must appear at even/odd indices in the list
-(2) - the list must have an even number of entries.
-
-Options:
- [0] - base io address
- [1] - irq (optional, but you probably want it)
-
-irq can be omitted, although the cmd interface will not work without it.

+KS7010 Linux driver
+===================
+
+This driver is based on source code from the Ben Nanonote extra repository [1]
+which is based on the original v007 release from Renesas [2]. Some more
+background info about the chipset can be found here [3] and here [4]. Thank
+you to all which already participated in cleaning up the driver so far!
+
+[1] http://projects.qi-hardware.com/index.php/p/openwrt-packages/source/tree/master/ks7010/src

+
+TODO
+----
+
+First a few words what not to do (at least not blindly):
+
+- don't be overly strict with the 80 char limit. Only if it REALLY makes the
+ code more readable
+- No '#if 0/1' removal unless the surrounding code is understood and removal is
+ really OK. There might be some hints hidden there.
+
+Now the TODOs:
+
+- fix codechecker warnings (checkpatch, sparse, smatch). But PLEASE make sure
+ that you are not only silencing the warning but really fixing code. You
+ should understand the change you submit.
+- fix the 'card removal' event when card is inserted when booting
+- check what other upstream wireless mechanisms can be used instead of the
+ custom ones here
+
+Please send any patches to:
+Greg Kroah-Hartman <gregkh@linuxfoundation.org>

- * 1. Define a new operation in cl_object_operations{}, says clo_depth,
- * which measures how many layers for this lustre object. Generally
- * speaking, the depth would be 2, one for llite, and one for lovsub.
- * However, for SNS, there will be more since we need additional page
- * to store parity;
- * 2. Reserve the # of (page_count * depth) cl_pages from the reserved
- * pool. Afterwards, the clio would allocate the pages from reserved
- * pool, this guarantees we needn't allocate the cl_pages from
- * generic cl_page slab cache.
- * Of course, if there is NOT enough pages in the pool, we might
- * be asked to write less pages once, this purely depends on
- * implementation. Anyway, we should be careful to avoid deadlocking.
