hwdrv_apci1564.c had numerous lines over the column limit. This patch
splits all such lines to bring them in compliance with coding style.

A handful of variables here were being initialized to 0 upon declaration,
however they are always then set to another value before their first use,
so initialization here is useless and we can remove it.

Just make a helper function so that you can call it like this:
static void outl_1564_timer(struct addi_private *devpriv, unsigned int cmd,
unsigned int reg)
{
outl(cmd, devpriv->i_IobaseAmcc + APCI1564_TIMER, reg);
}
Then the caller becomes:
outl_1564_timer(devpriv, cmd, APCI1564_TCW_PROG);

^^^
Should be "devpriv->i_IobaseAmcc + APCI1564_TIMER + reg" obviously.

This patch introduces a simple helper function, outl_1564_timer(), to
allow several lines which violate the character limit to be shortened.
A handful of other lines that are too long are appropriately split as
well.

A handful of variables here were being initialized to 0 upon declaration,
however they are always then set to another value before their first use,
so initialization here is useless and we can remove it.

Avoid forward declarations. Put the function itself here.
Do a function for APCI1564_DIGITAL_IP as well.
outl_1564_digital_ip()
inl_1564_digital_ip()
To be honest, I'm not sure how much the 1564 adds to the name. The
names should match of course.
I wonder if this line is buggy?:
outl(0x0, devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP_INTERRUPT_MODE1); /* Disable the and/or interrupt */
Should it be?
outl(0x0, devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP + APCI1564_DIGITAL_IP_INTERRUPT_MODE1);
You would need to read the specs to be sure.
Anyway, take some more time with this and play with different ways to
clean it up.
regards,
dan carpenter

Hey Dan!
Thanks a lot, I really appreciate all of the really good feedback. It's getting late now, but tomorrow I'll work on tidying everything up based on all of these comments and double check that hardware spec as well.
Thanks,

Greg,
You're right and that's totally my bad! In all honesty, I sent this as v2 of my original cleanup patch (without even
changing the subject :( ) when really, that was a mistake because it's pretty much a different patch entirely (although with
the same ultimate end goal). It needs further changes (based on Dan's comments) anyway, so when I send in the next version,
the subject will be changed appropriately. Sorry for my oversight, it won't happen again.
Thanks,
Chase

This patch introduces a handful of outl and inl helper functions with the
ultimate goal of improving code readability and allowing several lines
which violate the character limit to be shortened in a sane way.

This patchset serves as a replacement to my previous cleanup patchset for
hwdrv_apci1564.c
Dan,
After spending a little bit more time with this and trying out different
ways of cleaning this up, I decided that making helper functions for all
of the most common register sets would look the best, but I haven't made
a helper for a few of the least common inl/outl calls because if I did,
the sheer number of helper functions would get quite ridiculous.
Let me know if you think my selections of what to make into helper
functions seems appropriate.
Thanks,
Chase

We can use these inl and outl helper functions to improve code
readability and shorten several lines to under the character limit.

I checked over this all several times so I hope it is correct. I welcome
feedback on anything here
Thanks,

Yeah. You're right... It's kind of a lot of helper functions.
I wonder if we could just do something like:
static void outl_amcc(struct addi_private *devpriv, unsigned int cmd,
unsigned int reg)
{
outl(cmd, devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP + reg);
}
And then change APCI1564_DIGITAL_IP_INTERRUPT_MODE1 to be:
#define APCI1564_DIGITAL_IP_INTERRUPT_MODE1 (0x4 + 0x4)
The only problem with that would be i_APCI1564_Reset(). Is
i_APCI1564_Reset() buggy? Ian or Hartley might know. Take a look at
other comedi drivers as well to see what they do.

I like this idea. Just to clarify though, basically all of the macros would
change to something like
#define APCI1564_DIGITAL_IP 0x4 #define APCI1564_DIGITAL_IP_INTERRUPT_MODE1 (0x4 + 0x4) #define APCI1564_DIGITAL_IP_INTERRUPT_MODE2 (0x4 + 0x8) #define APCI1564_DIGITAL_IP_IRQ (0x4 + 0x10) #define APCI1564_DIGITAL_OP 0x18 #define APCI1564_DIGITAL_OP_RW 0x18 #define APCI1564_DIGITAL_OP_INTERRUPT (0x18 + 0x4) #define APCI1564_DIGITAL_OP_IRQ (0x18 + 0xc)
etc... and then we just have the single helper function
(the corrected version from your follow up email) and then
the calls would be something to the effect of:
outl_amcc(devpriv, cmd, APCI1564_DIGITAL_IP_INTERRUPT_MODE1);
or whichever macro is appropriate? It definitely trims down
the length of the function calls by removing the dereference of
devpriv and the addition to get the proper register...I like that.

I agree. I'll look into the other addi-data drivers (the layout of each
appears pretty similar) or see if Ian or Hartley can shed more light on the
reset function, because I have a sneaking suspicion that a good few of the lines
in it already are buggy, and it seems like there's a chance that it's not clearing
all of the registers that it should be, either. I could be wrong about that though.
At any rate, I'll see what I can do.
Thanks,
Chase

Ah shoot, well that was a copy/paste trainwreck. Let's try that again, the macros would
look something like:
#define APCI1564_DIGITAL_IP 0x4
#define APCI1564_DIGITAL_IP_INTERRUPT_MODE1 (0x4 + 0x4)
#define APCI1564_DIGITAL_IP_INTERRUPT_MODE2 (0x4 + 0x8)
#define APCI1564_DIGITAL_IP_IRQ (0x4 + 0x10)
#define APCI1564_DIGITAL_OP 0x18
#define APCI1564_DIGITAL_OP_RW 0x18
#define APCI1564_DIGITAL_OP_INTERRUPT (0x18 + 0x4)
#define APCI1564_DIGITAL_OP_IRQ (0x18 + 0xc)
There, that's better. Sorry about that.
Thanks,
Chase

This patch introduces a few simple outl and inl helper functions to allow
several lines which violate the character limit to be shortened
appropriately. It also changes a few macro values which represented
offset values from a single unique base value to instead represent the value
of that base plus the offset. This is to simplify the use of these macros
in the new helper functions.

All right, here's another shot at this. Dan, I took your outl_amcc idea
and did a version for the outl/inl calls based from devpriv->iobase as well.
I changed all of the macros which only offset from one base value as you
had mentioned as well, and the result is starting to look very good.
The only outl/inl calls which still look a little gross (see PATCH v2 2/2) are
the ones involving DIGITAL_OP_WATCHDOG, TIMER, or any of the COUNTER macros,
just because they use a common set of offset macros so simplifying
those calls in the same way as the rest isn't possible. What are your
thoughts on this version of the patchset?
This is version 2 of [PATCH 1/2] Staging: comedi: introduce outl_1564_* and
inl_1564_* helper functions in hwdrv_apci1564.c
2: Changed helper functions from {outl,inl}_1564_*() to
{outl,inl}_{amcc,iobase}()

Use the newly created helper functions to improve code readability and shorten
several lines to under the character limit.

I've reviewed this as best as I can, but I know it's a bear to review.
If there is some logical way that you'd like me to split this up into separate
patches to make it easier to review, please let me know.
Also, Dan, as best as I can possibly tell, i_APCI1564_Reset() is absolutely
buggy. When making up this patch, I made the changes that seem correct (and
somewhat obvious) from looking at the other addi-data drivers, the other
functions in this file, and the hardware specs that I could find, but
unfortunately I have no way to test the code.
This patch is version 2 of [PATCH 2/2] Staging: comedi: use outl_1564_* and
inl_1564_* helper functions in hwdrv_apci1564.c
2: Helper functions changed.

You can't change these without changing the callers. This bit needs to
be in patch 2/2. You should probably just merge both patches anyway
because presumably this one adds some GCC warnings about unused static
functions.

You need to put this into the commit message... You can't change how
the code works without at least mentioning it in the commit.
It would be easier to review these patches if you introduced the helpers
first and switched everything to use them. Then in 2/2 you changed the
defines to the combined versions.

This isn't indented correctly. It should be:
outl_amcc(devpriv, 0x0,
APCI1564_DIGITAL_OP_WATCHDOG + APCI1564_TCW_PROG);
[tab][tab][tab][space][space]APCI1564_DIGITAL_OP_WATCHDOG...
The same thing in a couple other places as well.

Chase,
Sorry for jumping in here late.
I think if you just tidy up the register map defines it would help. Some of them
are actually used incorrectly anyway.
For instance, these two define the "base" offset for the digital input registers,
which is also to digital input register, and the offset from the "base" to the
interrupt mode1 register.
#define APCI1564_DIGITAL_IP 0x04
#define APCI1564_DIGITAL_IP_INTERRUPT_MODE1 4
One use of the APCI1564_DIGITAL_IP_INTERRUPT_MODE1 define is in
i_APCI1564_ConfigDigitalInput():
outl(data[2],
devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP +
APCI1564_DIGITAL_IP_INTERRUPT_MODE1);
But in i_APCI1564_Reset () it is used as:
outl(0x0, devpriv->i_IobaseAmcc + APCI1564_DIGITAL_IP_INTERRUPT_MODE1);
So in the first example the driver is writing to a register at offset 0x08 (0x04 + 4) but
the second is writing to a register at offset 0x04 (4), which is really the digitial input
register.
I suggest you just fix the register map defines so they are the "real" offsets to each
register and not a mix of real offsets and adders to those offsets.
I would also rename them to help with the > 80 char lines.
Something like this:
/*
* devpriv->i_IobaseAmcc Register map
*/
#define APCI1564_DI_REG 0x04
#define APCI1564_DI_INT_MODE1_REG 0x08
#define APCI1564_DI_INT_MODE2_REG 0x0c
#define APCI1564_DI_INT_STATUS_REG 0x10
#define APCI1564_DI_IRQ_REG 0x14
#define APCI1564_DO_REG 0x18
#define APCI1564_DO_INT_CTRL_REG 0x1c
#define APCI1564_DO_INT_STATUS_REG 0x20
#define APCI1564_DO_IRQ_REG 0x24
#define APCI1564_WDOG_REG 0x28
#define APCI1564_WDOG_RELOAD_REG 0x2c
#define APCI1564_WDOG_TIMEBASE_REG 0x30
#define APCI1564_WDOG_CTRL_REG 0x34
#define APCI1564_WDOG_STATUS_REG 0x38
#define APCI1564_WDOG_IRQ_REG 0x3c
#define APCI1564_WDOG_WARN_TIMEVAL_REG 0x40
#define APCI1564_WDOG_WARN_TIMEBASE_REG 0x44
#define APCI1564_TIMER_REG 0x48
#define APCI1564_TIMER_RELOAD_REG 0x4c
#define APCI1564_TIMER_TIMEBASE_REG 0x50
#define APCI1564_TIMER_CTRL_REG 0x54
#define APCI1564_TIMER_STATUS_REG 0x58
#define APCI1564_TIMER_IRQ_REG 0x5c
#define APCI1564_TIMER_WARN_TIMEVAL_REG 0x60
#define APCI1564_TIMER_WARN_TIMEBASE_REG 0x64
/*
* devpriv->iobase Register map
*/
#define APCI1564_TCW_REG(x) (0x00 + ((x) * 20))
#define APCI1564_TCW_RELOAD_REG(x) (0x04 + ((x) * 20))
#define APCI1564_TCW_TIMEBASE_REG(x) (0x08 + ((x) * 20))
#define APCI1564_TCW_CTRL_REG(x) (0x0c + ((x) * 20))
#define APCI1564_TCW_STATUS_REG(x) (0x10 + ((x) * 20))
#define APCI1564_TCW_IRQ_REG(x) (0x14 + ((x) * 20))

#define APCI1564_TCW_WARN_TIMEBASE_REG(x) (0x1c + ((x) * 20))
You will probably want to split this into a couple patches to make reviewing
easier. Maybe do it by subdevice: digital input, digital output, watchdog, timer,
then the counters.
Regards,
Hartley

I'm totally confused about this series...
Chase, can you resend any outstanding patches that I haven't applied of
yours, as these different revisions and threads don't make much sense
right now.

Greg,
Yes, admittedly this whole thing has gotten a little messy :P sorry for all the confusion.
I've finally spoken with Hartley about how to best clean this driver, and so I will submit
a final patchset to you as soon as I finish up with it. Until then, please just disregard
all prior patches to hwdrv_apci1564.c from me, as the one I send next will supersede all of them
and I will clearly mark it as such for you.
Thanks,
Chase
