[PATCH 1/6] staging: comedi: addi_apci_1564: remove eeprom support code

[Chase Southwood]

Reading the eeprom on this board is not necessary.  All information
required is in the boardinfo.

Remove the eeprom support code which is not really useful here.

[PATCH 3/6] staging: comedi: addi_apci_1032: board has 32 digital inputs

[Chase Southwood]

This board always has 32 digital inputs. Remove the test when
initializing the subdevice.

Also, since this board is the only one supported by this driver,
remove the boardinfo about the digital inputs and just use the
data directly in the subdevice init.

Hartley,

As far as I can tell from reading the I/O Mapping you sent me, these bar
numbers are correct, but it seems a bit odd, so please offer correction
if I am interpreting the document incorrectly.

Ian and Hartley,

The auto_attach() function is starting to look much better now.  My next patchset
will be geared towards only allocating subdevices which are actually used.

I'm sure the original resources are correct, so since 
this_board->i_IorangeBase1 is non-zero:

	dev->iobase = pci_resource_start(pcidev, 1);
	devpriv->i_IobaseAmcc = pci_resource_start(pcidev, 0);

I suspect the member name 'i_IobaseAmcc' is just a hangover from the 
distant past and could just be changed to 'iobasemain' or something, 
since most of the code seems to use it.

Maybe this depends on the revision of the board, though.  The documents 
Chase saw were for APCI1564 revision D, but the PCI BAR assignments 
might have been different for earlier revisions of the board.

All the driver code I've ever seen for this board (including one of 
ADDI-DATA's own Linux drivers, which no longer seems to be available for 
download) has used PCI BARs 0 and 1 with the same functions as the 
comedi driver.

Most "off-the-shelf" PCI interface chips reserve at least PCI BAR 0 for 
their own registers.  The clearest image I've found of this board seems 
to have an Altera ACEX FPGA with built-in PCI interface, so it might not 
have that restriction on BAR 0.

http://pcqt.com/DAQ/images/apci-1564-400.jpg

I think it's best to stick with the existing BAR assignments until 
proved otherwise.

[Chase Southwood]

Hartley,

Ah geez...my brain got all tangled looking at old git commits for
other addi-data drivers.  I apologize for this silly mistake.  I'll
fix that title and send a new version of the patchset tomorrow.

Thanks,
Chase

Re: [PATCH 4/6] staging: comedi: addi_apci_1564: simplify the PCI bar reading and don't read the unused bars

[Chase Southwood]

Hartley and Ian,

Yes, I had a feeling I should have gone with what was present, but my
desire to follow the documentation I wasn't too familiar with won out
:P

I'll spin a new revision of this patchset ASAP with this changed back
and all of my bad titles (oof...) fixed as well and I'll make sure to
be more careful in the future.

Thanks your all of the assistance and patience,
Chase

[PATCH 3/6 v2] staging: comedi: addi_apci_1564: board has 32 digital inputs

[Chase Southwood]

This board always has 32 digital inputs. Remove the test when
initializing the subdevice.

Also, since this board is the only one supported by this driver,
remove the boardinfo about the digital inputs and just use the
data directly in the subdevice init.

The description needs fixing as it's back to using PCI bar 0 and 1. 
Also, there's a typo: doon't -> don't. :)

Other than Ian's comment on patch 4/6 everything looks good to me.

Ian and Hartley,

Thanks so much, I greatly appreciate the review.  I'll fix the
changelog for patch 4 and send once more (as I assume that's easier
for Greg).  Also, I should know better about the cover letter as
well...I was once told not to send them for strictly cleanup patchsets
(as Greg can't do anything with them and cleanups should be obvious)
but I've gotten in the habit of not doing a cover letter for any
patchsets.  I will send cover letters (and be more careful about my
other mistakes) in the future.

Thanks,
Chase

Chase,

Good job on the cleanup you have done so far.

The cover letter does not get committed as part of the patch set. But
when you are submitting a series it give a convenient  place to add
the sign off tag for a series. Also, if you would have done a cover letter
for this series you would have probably spotted the subject line issues
in patches 5 and 6.

Keep up the good work!

Hartley

Hartley,

Yes, you raise very good points.  In any case, I have added cover
letters to my submitting checklist so hopefully everything will be a
lot easier for everyone next go round.

Thanks,
Chase

[PATCH 6/6 v3] staging: comedi: addi_apci_1564: remove use of devpriv->s_EeParameters

[Chase Southwood]

This driver no longer reads the eeprom to find the board specific data,
all the necessary data is in the boardinfo. Use the boardinfo directly
instead of passing through devpriv->s_EeParameters.

2: Incorrect patch title fixed.

3: I apparently failed to redo this patch properly when I changed PATCH 4/6 and
it no longer applied.  Just noticed this, and verified that the whole series
applies now.

Same here, it's great to see all of this cleanup happening.  Maybe
someday it can move out of staging...  :)

Thanks everyone! :) Yeah, I suppose it would be nice to see comedi
graduate, eh?  AFAICT, it looks like it's been hanging around in
staging a while...

Thanks,
