Split the "amplc_dio200" comedi driver module into separate driver
modules for ISA and PCI boards with a common module for the shared code.

Keep the old name "amplc_dio200" for the ISA board driver as the module
may be modprobed with this name by a script.  (If the script uses insmod
it will need modifying to load the "amplc_dio200_common" module first.)

Use the module name "amplc_dio200_pci" for the PCI board driver.  On
most systems this will be auto-loaded.

Use the module name "amplc_dio200_common" for the module containing the
shared code.  This is normally loaded as a dependency of the other two
modules.

"amplc_dio200_common" exports the following functions:

* `amplc_dio200_common_attach()`: this is basically the old
  `dio200_common_attach()` from the combined driver module.  It is
  called from the driver-specific attach or auto-attach routines.
* `amplc_dio200_common_detach()`: this is most of the old
  `dio200_detach()`.  It is called from the driver-specific detach
  routine.
* `amplc_dio200_set_enhance()`: this is a new function called during
  initialization of PCIe cards to enable "enhanced" mode.

The "amplc_dio200" driver is going to be split into separate drivers for
ISA and PCI cards with a common module containing most of the code.  We
don't want the common module code to depend on whether ISA boards, PCI
boards, or both are supported.  Currently, `dio200_common_attach()` and
`dio200_detach()` optimize out the code to support a timer subdevice
when built to support ISA boards only.  Remove the `if (DO_PCI)` tests
which optimize out that code.  Unfortunately, this will expand the

staging: comedi: amplc_dio200: embed board layout in board structure

The amplc_dio200 driver supports both ISA and PCI boards, some of which
are quite similar.  The driver takes advantage of this by defining a
"board layout" structure `struct dio200_layout` along with an array of
this structure `dio200_layouts[]` and an enumerated type for the indices
into this array `enum dio200_layout_idx`.  The main board information
structure `struct dio200_board` contains a `layout` member holding an
enumerated index into the array of layouts and the enumerated layout
values are used to designate the indices in the initializer of
`dio200_layouts[]`.

We would like to split the ISA and PCI support into separate driver
modules and having the shared layouts makes this slightly awkward as the
enumerated values are condionally present depending on whether the
driver is configured to support ISA, PCI, or both.

Embed the `struct dio200_layout` into the main board information
structure `struct dio200_board` to make things simpler, discarding
`dio200_layouts[]` and the `enum dio200_layout_idx` in the process.
Only two of the layouts were used by more than one board anyway (each of
which was used by one ISA and one PCI board).

While we're at it, change the `has_int_sce`, `has_clk_gat_sce` and
`has_enhancements` members of `struct dio200_layout` to `bool:1`
bit-fields to save a few bytes.

Set the `driver_data` member of each element (apart from the sentinel)
of our PCI device table `dio200_pci_table[]` to the index of the
corresponding element of our private PCI board details
`dio200_pci_boards[]`.  This index appears in the context parameter of
our auto_attach routine `dio200_auto_attach()`.  In this function,
nename the parameter to `context_model` and use it to set
`dev->board_ptr` to point to an element of `dio200_pci_boards[] directly
by index instead of calling `dio200_find_pci_board()` to search for the
element whose `devid` member matches the PCI device ID.

Remove `dio200_find_pci_board()` and the `devid` member of `struct
dio200_board`.  Also remove the `model` member of `struct dio200_board`
and the `enum dio200_model` type as we can do without them.  The only
function that uses the `model` member is `dio200_auto_attach()`, so use
the `context_model` parameter instead.

Define the enumerated value for each PCI board in new type `enum
dio200_pci_model` which replaces `enum dio200_model` minus the
enumerated values for the ISA boards (so the numeric values for the PCI
boards have changed).  Use these enumerated values to designate the

Merge tag 'iio-for-3.10a' of git://git./linux/kernel/git/jic23/iio into staging-next

Jonathan writes:

First set of IIO new drivers and cleanup for the 3.10 cycle.

New stuff

1) Add OF support for specifying mappings between iio devices and their
   in kernel consumers.
2) Driver for AD7923 (extra functionality and support for ad7904, ad7914 and
   ad7924 added later in series)
3) Driver for Exynos adc (dt suppor for phy added later in series).
4) Make iio_push_event save IRQ context - necessary if it is to be used
   within an interrupt handler.  Users of this functionality to follow.
5) For iio use the device tree node name to provide the hwmon name attribute
   if available.

Removal and moves out of staging

1) Drop the adt7410 driver from IIO now that there is a hmwon driver with
   equivalent support. This device is very much targeted at hardware
   monitoring so hwmon is a more appropriate host for the driver.
2) Move iio_hwmon driver to drivers/hwmon.

Cleanups

1) Minor cleanup in ST common library.
2) Large set of patches to break the info_mask element which previously used
odd and even bits to specify if a channel attribute was either shared across
similar channels or specific to only one.  Now we have two bitmaps, one for
those parameters that are specific to this channel and one for those shared
by all channels with the same type as this one.  This has no effect on the
userspace abi. It simplifies the core code and provides more space for new
channel parameters. It has been on the todo list for a long time!

Conflicts:
drivers/iio/dac/ad5064.c

hwmon: Move the IIO client driver for hwmon out of staging

This driver uses channel maps, defined either through device tree
or platform data, to create a hwmon driver which acts as a client
for the underlying IIO device channels.  Thus a general purpose
IIO adc driver can be used to provide hardware monitoring using a subset
of its channels.

 The only non move changes here concern the description and changes to the
 dependencies to IIO explicit and hwmon implicit.

 I'm proposing moving this into hwmon on the basis of placing drivers
 based on what they provide rather than what their underlying hardware
 is.
