Since the regualtor can't change voltage specifying the voltage here
isn't going to achieve anything - to get the voltage reported through
get_voltage() you need to put the voltage in the platform data for the
fixed regulator.

In the ADC regulator patch you called the supply vdd (though the chip
normally calls it vadc so that's the better name)...
Extra ' too.

I'm not sure both the #define and the variable make sense here...

Since the regualtor can't change voltage specifying the voltage here
isn't going to achieve anything - to get the voltage reported through
get_voltage() you need to put the voltage in the platform data for the
fixed regulator.

Um.. this happened as I have seperated NURI-board platform patch for
ADC and PMIC.
After ADC patch, that name became ("vdd", "s5p-adc").
I'll let them either be merged or be disjoint completely.
Anyway, do you think "vadc" is better than "vdd" for ADC drivers? The
circuit schematics says the pin on the consumer side is "VDD33_ADC"
(VDD 3.3V for ADC).

Anyway, I've got a question about using __initdata for platform_data entries.
Using __initdata on this entry and other max8997's platform_data did
not create any SECTION MISMATCH warnings.
"Documentation/DocBook/kernel-hacking.tmpl" says, __initdata means
that the content of it may be free'd after boot.
However, the MAX8997 driver uses platform_data's entry (variables
defined in "static struct max8997_platform_data __initdata
nuri_max8997_pdata)
in its normal functions other than its probe function, which are often
called after boot.
Probably, I'm thinking wrong in some place; however, it seems that
there should be SECTION MISMATCH warnings as the MAX8997 driver uses
the pdata, which is declared to be __initdata, in non-_init function.
Or, is it safe to use platform_data (by dev_get_platdata) out of probe
in drivers even if the platdata is declared to be __initdata in the
platform files?
I just can't sure whether I should let probe function copy
platform-data used by non-probe functions to its own local data
assuming that the content may be freed (assuming that the SECTION
MISMATCH warning is not "complete".) or just believe the completeness
of gcc's SECTION MISMATCH warning.
Cheers!

You may as well get it right to start off with, there's no harm
defining a supply that doesn't get used.

If that's what the pin is called on the package that is the best name
to use.

Right, but there's no point in doing both - either use the #define
everywhere or use the variable everywhere but having both seems
excessive.

Will it be possible to move PMIC specific defines to a common file and
make appropriate calls in the board-specific file?
In that way, we can re-use this PMIC code on some other boards (e.g.
Insignal low-cost board Origen featuring Exynos4210 also features MAX8997).

Why not do this in an initcall or in the device registration? This
looks like working around a limitation of the ntc_thermistor driver
which should be fixed as part of a mainline merge for that.

This looks like debug that was left in by mistake.

This looks good, though you should also be able to make the supply lists
into __initdata.

If the board is similar enough in design to be sharing the PMIC code
that sounds like it should be sharing a lot more of the board setup
code.

If the board is similar enough in design to be sharing the PMIC code
that sounds like it should be sharing a lot more of the board setup
code.

Origen board details can be found at http://www.origenboard.org/
Under 'Documents' section, there are some schematics for the board.
As for other peripherals, I am not sure how much similar this is w.r.t.
NURI (I don't have NURI board schematics).

Right, and we can't really make the assessment about sharing the code if
we can't do a contrast and compare between the two schematics (or look
at the resulting code).

Yes, we have tried creating PMIC defines at a seperated file in our
local repositories (still doing so in those repositories).
However, that ended up creating multiple PMIC defines (one PMIC define
file for each board); the connections between LDO# and devices are
different.

Well, I cannot find enough information to match PMIC device data from
the schematics in that 'Documents' section. It appears that they
provide every information but the PMIC-related.

In that case, we can first post the Origen board support and PMIC code
on the ML, then we would see if we can consolidate.
That looks more logical as per Mark's suggestion also.

Right, not just yet. I should've added comment about the patch just
being applied to "next".
I've added it as it was told to be applied to "next" in lm-sensors by
Guenter Roeck yesterday.

Um... I think I can put this away to a common plat-samsung/dev-ntc.c
as I've seen many S5PC110/S5PV210/Exynos4 devices using NTC attached
to the CPU's ADC ports.
However, I won't be able to put that part into the NTC driver because
using S3C-ADC is plat-samsung specific method and NTC thermistor
itself is a general thermistor device not specific to S3C. Maybe, I
can do so after we've got a common ADC framework.

Hi Tushar,
When you need to add similar or same functionality on your board, you can/should move it in common part.
Maybe 'should'...basically, nobody will apply same function into both place...
Thanks.
Best regards,

Yes, but it's not just the location of the code - I was mostly noticing
the fact that it was doing something that's clearly supposed to be a
probe() method in the main read function. It'd be better if there were
an explicit probe() and corresponding remove() interface.
I also note that this callback based stuff won't work terribly well with
device tree.

Yes, we really need to get that ADC stuff sorted soon :(
