Second set of IIO rework and new drivers for the 3.7 cycle. Firstly we have the second half of a series reworking support for the various sigma delta ADCs from Analog. The first half was fixes that have already merged in the v3.6 cycle. Other than some little cleanups this mainly consists of a unifying library module that the various drivers can then use. Another new driver is using this undergoing revisions and the code reduction already seen from this is considerable. A nice piece of work. Secondly we have a good number of tidying up patches from various sources doing things like adding include guards and removing unintended header ordering requirements. Also a mass annotation of missing __devinit/exit. Peter Meerwald has been getting around with cleanup of lis3l02dq, documentation fixes, white space clenaups and a small issue with my spelling ;) Thirdly we have some improvements to our kfifo usage that have been around for a while but are now suddenly in demand from a number of users. Forth we have some clk_prepare_enable and clk_prepare_disable cleanups. Fifth is the addition of i2c dacs to the ad5446 driver Finally we have some email address updates. I'll do the MAINTAINERS one separately. So a general mixed bag but nothing terribly controversial or 'exciting'.

The `IS_ENABLED(CONFIG_COMEDI_DAS08_ISA)` and `IS_ENABLED(CONFIG_COMEDI_DAS08_PCI)` macro calls are a bit long-winded. Define a couple of macros `DO_ISA` and `DO_PCI` as abbreviations for them. Signed-off-by:

Add inline helper function `is_isa_board(board)` to check if the driver supports ISA boards and this is an ISA board, and `is_pci_board(board)` to check if the driver supports PCI boards and this is a PCI board. Signed-off-by:

Don't bother reporting the I/O base address for PCI devices as it's not very interesting. Signed-off-by:

Absorb `das08_pci_attach_common()` into `das08_attach_pci()` since that's the only place it was called from. Signed-off-by:

Remove the code that allows PCI boards to be manually attached by the `COMEDI_DEVCONFIG` ioctl (or the `comedi_config` application). Supported PCI boards will be attached automatically at probe time via `comedi_pci_auto_config()` and the `attach_pci` hook in the `struct comedi_driver`. Signed-off-by:

Stash the last value written to each AO channel in private data and support the INSN_READ instruction to read it back. Don't bother setting the SDF_READABLE subdevice flag though as the hardware isn't really readable - we're just faking it. Signed-off-by:

Ian Abbott authored
Initialize the AO subdevice channels to mid-range data value so they are in a known state. This allows us to support reading back the current value in a later patch. Signed-off-by:

Ian Abbott authored
Combine the AO write functions for 'JR' boards and other boards into a single function and factor out the data writing from the comedi instruction handling so it can be called from elsewhere in a later patch. Signed-off-by:

The `das08jr_di_rbits()`, `das08jr_do_wbits()`, `das08jr_ao_winsn()` and `das08ao_ao_winsn()` static functions are currently marked as `__maybe_unused` as they were formerly only referred to by possibly conditionally compiled out code. This is no longer the case (they are referred to by `das08_common_attach()`) so their `__maybe_unused` tags can be removed. Signed-off-by:

There is no need to check the value of `insn->n` is correct in `das08_counter_config()` as the core comedi module will have already checked it. Signed-off-by:

The I/O port base address for the counter subdevice doesn't need to be stored in the private data. It can be calculated on the fly using the offset in the static board data. Signed-off-by:

The `pci_iobase` I/O port registers from PCI BAR 1 are never accessed, so don't bother storing this base address in `struct das08_private_struct`. The `pci_iobase` member was checked for non-zero in `das08_detach()` but we can check `dev->iobase` is non-zero instead. Signed-off-by:

Move `das08_cs_boards[]` from "das08.c" to "das08_cs.c" and make it static const. It no longer refers to anything in "das08.c" and no longer needs to be exported. Signed-off-by:

Don't bother initializing the `i8255_offset` and/or `i8254_offset` members of `struct das08_board_struct` in `das08_boards[]` and `das08_cs_boards[]` if they are zero as they are implicitly initialized to zero anyway, and zero means the corresponding subdevices are absent. Signed-off-by:

Ian Abbott authored
Remove the `ai`, `ao`, `di` and `do` pointers from `struct das08_board_struct`. These were initialized in `das08_boards[]` and `das08_cs_boards[]` to point to comedi instruction handler functions for the subdevice, but there are only two sets of functions depending on whether the `is_jr` member is true or false, and some of the functions will be NULL if the corresponding `ai_nbits`, `ao_nbits`, `di_nchan` and `do_nchan` members are zero. Determine which handler functions to use in das08_common_attach(). One element of `das08_boards[]` had `ao` set to NULL and `ao_nbits` set to 12. Set `ao_nbits` to 0 in this case to let das08_common_attach() know this board has no AO subdevice. Signed-off-by:

Add a bool member `is_jr` to `struct das08_board_struct` and initialize it to `true` in those elements of `das08_boards[]` corresponding to the 'JR' board models. This will be used by a following patch that removes the `ai`, `ao`, `di` and `do` members from `struct das08_board_struct`. Signed-off-by:

Ian Abbott authored
Add member `di_nchan` to `struct das08_board_struct` to set the number of digital input channels explicitly. Currently, the code determines the number of channels to 3 or 8 depending on what function the `di` member points to, which is not very elegant. Signed-off-by:

Remove the `pc104` value from `enum das08_bustype` and replace occurrences of it in the code and data with the `isa` value. The code treats them as equivalent anyway with expressions like `(thisboard->bustype == isa || thisboard->bustype == pc104)`. Signed-off-by:

Don't zero out bits 15..12 of the data value in `das08jr_ao_winsn()` as that knobbles the upper three-quarters of the output range for the 'das08jr-16-ao' board. Cc: stable <stable@vger.kernel.org> Signed-off-by:

Ian Abbott authored
The element of `das08_boards[]` for the 'das08jr-16-ao' board has the `ai_encoding` member set to `das08_encode12`. It should be set to `das08_encode16` same as the 'das08jr/16' board. After all, this board has 16-bit AI resolution. The description of the A/D LSB register at offset 0 seems incorrect in the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI resolution is only 12 bits. The diagrams of the A/D LSB and MSB registers show 15 data bits and a sign bit, which matches what the software expects for the `das08_encode16` AI encoding method.

Ian Abbott authored
When attaching a PCI device manually via the comedi driver `attach` hook (`das08_attach()`) (called by the comedi core for the `COMEDI_DEVCONFIG` ioctl), its reference count is incremented in the `for_each_pci_dev` loop (in `das08_find_pci()`). It is decremented when the `detach` hook (`das08_detach()`) is called to detach the device. However, when the PCI device is attached automatically via the `attach_pci` hook (`das08_attach_pci()`, called at probe time via `comedi_pci_auto_config()`) it's reference count is not incremented so there will be an unmatched decrement when detaching the device. Increment the PCI device reference count in `das08_attach_pci()` to correct the mismatch. Once support for manual configuration has been removed from this driver, the calls to `pci_dev_get()` and `pci_dev_put()` can be removed. Signed-off-by:
