When requesting optional GPIO echo line, bail out on error,
so user will know that something wrong with the existing property.

When GPIO APIs return -EPROBE_DEFER there is no need to print the message,
especially taking into consideration that it may repeat several times.
Use dev_err_probe() to avoid log noise in such cases.

The timer along with GPIO API are NULL-aware, there is no need to test
against existing GPIO echo line.

Platform data is a legacy interface to supply device properties
to the driver. In this case we even don't have in-kernel users
for it. Just remove it for good.

Device property API allows to gather device resources from different sources,
such as ACPI. Convert the drivers to unleash the power of device property API.

In most parts of the code the platform device is not used.
Use struct device pointer directly to reduce code size and
increase readability.

Rearrange optional stuff in pps_gpio_setup() so it will go after mandatory one
and with reduced indentation. This will increase readability of the sources.

I'm sorry but I suppose I missed this patch... -_-'

Can you please resend it to me?

Ciao,

Entire series (7 patches) has been Cc'ed to you :-)

> Can you please resend it to me?

Okay, I will resend with Greg included just in case.

Done!

For the future, I recommend to switch to b4 tool (most likely already in your
Linux distribution), so

0/ Install b4 tool (if not yet in distro: `pip install b4` should work)
1/ Find message ID for the thread, for example,
	20210216113154.70852-1-andriy.shevchenko@linux.intel.com (v1)
	20210309112403.36633-1-andriy.shevchenko@linux.intel.com (v1 resend)

2/ `b4 am -s $MESSAGE_ID`, replace $MESSAGE_ID with one of the above
3/ it will download a mailbox that you may apply with `git am ...`
