H Hartley Sweeten 05fcdcede0 staging: comedi: addi_apci_2032: fix interrupt support
This board supports two interrupt sources:

VCC : detects when the external supply voltage drops below 5V
CC  : over temperature diagnostic

Currently the interrupt support is tied into the digital output
subdevice. It's also broken since it does not follow the comedi
API.

Create a new digital input subdevice to handle the interrupts.

H Hartley Sweeten 23fb174746 staging: comedi: addi_apci_2032: fix the watchdog timer subdevice
The watchdog timer on this board functions exactly like the one on
the apci_1516 board. Fix the i_APCI2032_StartStopWriteWatchdog and
i_APCI2032_ConfigWatchdo functions so that the watchdog follows the
comedi API.

Rename the CamelCase function i_APCI2032_StartStopWriteWatchdog to
apci2032_wdog_insn_writ. This function is used to "ping" the watchdog.

Rename the CamelCase function i_APCI2032_ConfigWatchdog to
apci2032_wdog_insn_config. This function is used to enable/disable
the watchdog and set the timeout.

H Hartley Sweeten dce10abc49 staging: comedi: addi_apci_2032: remove use of struct addi_private
The only data in addi_private used in this driver is:

tsk_Current - used with send_sig to signal userspace when an interrupt
has occurred. Interrupt support in this driver does not follow the
standard comedi API so this functionality is currently broken. This
will be addressed.

b_OutputMemoryStatus - used in the addi-data "common" code to enable
reading of the eeprom. Eeprom support is not needed by this driver
and has been removed.

Ian Abbott 971b5e5653 staging: comedi: me_daq: remove broken workaround for PLX bug
The PLX PCI 9050 interface chip has a bug where its local configuration
registers accessible through PCI BAR 0 and/or PCI BAR 1 (depending on
settings loaded from a serial EEPROM or local bus processor) are
unreadable (always read 0 instead of the true register values) if the
base address starts on an odd multiple of 0x80 (i.e.  has bit 7 set to
1).

The "me_daq" driver attempts to work around this by writing to the PCI
config space to swap the addresses assigned to PCI BAR 0 and PCI BAR 5
(which has been initially configured by serial EEPROM load as a spare
region of the same length as the PCI BAR 0 region).  (If the PCI BAR 5
region is absent, it attempts to reduce the PCI BAR 0 address by 0x80,
which is likely to cause havoc for some other device, but that case
shouldn't be reachable in practice.)

The workaround in the driver is ineffective because it has already
ioremapped the memory from `pci_resource_start(pcidev, 0)` *before* it
does the workaround, so after swapping PCI BAR 0 and PCI BAR 5, this
memory will end up accessing whatever onboard registers PCI BAR 5 was
linked to instead of the local configuration registers.  It also leaves
the addresses in the physical PCI BAR registers set differently to the
resource start addresses recorded in the `struct pci_dev`.

The workaround could be fixed by ioremapping `pci_resource_start(pcidev,
5)` if the PCI BAR addresses were physically swapped (and the fallback
workaround of subtracting 0x80 from the base address should really be
removed altogether).  However, it's not really worth it.  This sort of
thing should be worked around in "drivers/pci/quirks.c" by ensuring that
PCI BAR 0 and/or PCI BAR 1 do not end up on an odd multiple of 0x80
bytes.

Ian Abbott a588da1d5a staging: comedi: simplify comedi_auto_attach()
`comedi_auto_config()` just calls internal function
`comedi_auto_config_helper()`, passing it a wrapper function
`comedi_auto_config_wrapper()` to handle the specifics of checking and
calling the low-level comedi driver's `auto_attach()` handler.

Since there are no other callers of `comedi_auto_config_helper()` or
`comedi_auto_config_wrapper()`, combine everything into the single
exported function `comedi_auto_config()`.

Change the ordering of the check for existence of the low-level comedi
driver's `auto_attach()` handler and the allocation of the comedi minor
device number.  This means the log message warning of the absence of the
handler now has to be refer to the hardware device instead of the
not-yet-allocated comedi device.

Ian Abbott 206cb10816 staging: comedi: define operations for INSN_CONFIG_DIGITAL_TRIG
The 'addi_apci_1032' driver recently started supporting the
`INSN_CONFIG_DIGITAL_TRIG` configuration instruction, but as no other
drivers were using it before, there was no existing practice of how the
instruction should look.

Define the format to be something a bit more configurable.  In
particular, a subdevice might have more than one trigger requiring an ID
and/or `COMEDI_EV_...` flags to disambiguate them, a trigger might have
more than 32 inputs, and a trigger might need several
`INSN_CONFIG_DIGITAL_TRIG` configuration instructions to configure
completely (if there are more than 32 inputs or if it uses a combination
of edge-triggered and level-triggered inputs).

Ian Abbott b0a2b6d8ac staging: comedi: check data length for INSN_CONFIG_DIGITAL_TRIG
The newly defined format for the `INSN_CONFIG_DIGITAL_TRIG`
configuration instruction expects 6 data values.  Check the length in
`check_insn_config_length()` before calling the comedi subdevice's
`insn_config` handler.

Ian Abbott 33cdce6293 staging: comedi: addi_apci_1032: conform to new INSN_CONFIG_DIGITAL_TRIG
Conform to the new definition of the `INSN_CONFIG_DIGITAL_TRIG`
configuration instruction.

Return an error if the 'trigger number' in `data[1]` is non-zero or if
the configuration operation in `data[2]` is not supported.  Deal with
the 'left-shift' amount in `data[3]`.

The trigger's input channels can only be configured as a set of rising
and falling edges ('OR' mode) or as a set of high and low levels ('AND'
mode).  Preserve the old input channels to the right of the 'left-shift'
value except when switching modes.

(The 'left-shift' support is a bit of an overkill for this driver since
the trigger only has 16 input channels.)

Use the new helpers in the step 3 tests of ni_{ai,ao,cdio}_cmdtest().

Note that all the command triggers in ni_cdio_cmdtest are single source
so the extra tests are not required.
