+ * 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
+ * timebase/reload operation please let me know.
+ *
+ * The counter subdevice also does not use an async command. All control is
+ * handled by the (*insn_config).
+ *
+ * FIXME: The operation of the counters is not really described in the
+ * datasheet I have. The (*insn_config) needs more work.

-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

+ * 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.
+ *
+ * Configuration 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.

-Notes:
- IRQ can be omitted, although the cmd interface will not work without it.
-
- All entries in the channel/gain list must use the same gain and be
- consecutive channels counting upwards in channel number (these are
- hardware limitations.)
-
- I've never tested the gain setting stuff since I only have a

-
- The cio-das802/16 does not have a fifo-empty status bit! Therefore

+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
+[2] http://downloads.qi-hardware.com/software/ks7010_sdio_v007.tar.bz2
+[3] http://en.qi-hardware.com/wiki/Ben_NanoNote_Wi-Fi
+[4] https://wikidevi.com/wiki/Renesas
+
+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>
+Wolfram Sang <wsa@the-dreams.de>

- * 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.
