Arnd Bergmann 70db384cd6 staging: comedi: avoid using timeval
Comedi uses 32-bit seconds for its timestamps, on both 32-bit and
64-bit machines. For all I can tell, this was originally meant as
a 'timespec', which would overflow in 2038 because of the use of
a signed 'long' on 32-bit machines, but it is now used as an
array of two unsigned 'lsampl_t' values in comedilib, which will
only overflow in 2106, on both 32-bit and 64-bit machines.

In an effort to get rid of all uses of 'struct timeval' in the kernel,
this replaces the internal code with a call to ktime_get_real_ts64()
and a comment at the location of the conversion.

H Hartley Sweeten 931987a0c6 staging: comedi: addi_apci_1564: clarify change-of-state interrupt support
This board supports change-of-state interrupts on digital inputs 4 to 19
not 0 to 15.

The current code "works" but it could set inappropriate bits in the mode1
and mode2 registers that setup which channels are enabled. It also doesn't
return the status of the upper 4 channels (19 to 16).

Fix the comment and mask the mode1/mode2 values so that only the interrupt
capable channels can be enabled.

Add the SDF_LSAMPL flag to the subdevice so that 32-bit samples are used
instead of 16-bit ones. This allows returning the upper 4 channels. Use
the remaining bits in the sample to return "event" flags to the user.

The timer and counter subdevices can also generate interrupts and are a bit
hacked. They don't currently follow the comedi API and they use send_sig()
to let the task that know that the interrupt occured. The "event" flags will
be used instead when these subdevices are fixed.

Ian Abbott 457bec0f73 staging: comedi: plx9080.h: tidy up some comments
Use the usual block comment style and remove some excess spaces from
single-line comments.  Remove some obvious stuff about register offsets
being zero relative.  Remove some text about the original history of the
file, as it bears hardly any resemblance to it now.

Ian Abbott eb89333146 staging: comedi: drivers: add PLX PCI 9080 DMATHR register values
Add macros in "plx9080.h" that define values for the DMATHR register
values.  Use the prefix `PLX_DMATHR_` for the macros.  Make use of the
`BIT(x)` and `GENMASK(h,l)` macros to define the values.

Ian Abbott 3dcf1b5596 staging: comedi: drivers: re-do PLX PCI 9080 DMACSRx register values
Replace the existing macros in "plx9080.h" that define values for the
DMACSR0 and DMACSR0 registers.  Use the prefix `PLX_DMACSR_` for the
macros.  Make use of the `BIT(x)` macro to define the values.

Ian Abbott dde90d89ae staging: comedi: drivers: re-do PLX PCI 9080 DMADPRx register values
Replace the existing macros in "plx9080.h" that define values for the
DMADPR0 and DMADPR1 registers.  (A little-endian version of the register
value is also placed in the `next` member of `struct plx_dma_desc`.)
Use the prefix `PLX_DMADPR_` for the macros.  Make use of the `BIT(x)`
and `GENMASK(h,l)` macros to define the values.

Ian Abbott df04d3aa02 staging: comedi: plx9080.h: add hard-coded PCIHIDR register value
For the PLX PCI 9080, the read-only PCIHIDR register is hard-coded with
the value `0x908010b5`.  Add a macro `PLX_PCIHIDR_9080` that expands to
this value.
