[PATCH v1 1/1] iio: adc: mxs-lradc-adc: Get rid of OF specifics

[Andy Shevchenko]

First of all, the additional conversion from vIRQ, and this is exactly
what is returned by platform_get_irq_byname(), to vIRQ is not needed.
Hence, drop no-op call to irq_of_parse_and_map().

Second, assign the firmware node instead of of_node.

Confusing sentence form.  Perhaps:

First, the additional conversion from vIRQ (returned by platform_get_irq_byname())
to vIRQ is not needed.

Hi,

Seems sensible to me, but I'd like a sanity check from someone more
familiar with this driver.

Thanks,

Jonathan

This one has been outstanding for a few weeks. I'd still like
an Ack or similar form someone who knows this device well.

If no one has looked at it in a week or so I'll just go with
my judgement and pick it up.

#include <linux/property.h> needs to be included, otherwise the build fails.

I tried to apply the same change inside

If you send a v2 with "#include <linux/property.h>" then you can add:

I stand corrected, the fwnode assignment is done fore the IIO parent's parent,
it's needed...

So just to be sure. You got it before the above change applied, correct?

I'm wondering how this all LRADC was supposed to work. The IRQs are assigned
based on abstract numbering without any IRQ domain behind it. This is not how
it's designed in Linux. Adding Ksenija and Marek to shed a light.

Correct. This warning is an old one. See:

Any news on this one? Maybe I need to resend with the better commit message?

Ah, I only read last messages in the thread and didn't realized that I have
some ARs to accomplish. OK, v2 will come soon, thanks!

After reading more of the thread I think this patch should be in a different
form, so no v2 soon, needs more investigations.
