[PATCHv2 0/4] Add Altera A10SR Status & Control Monitor

[tthayer]

From: Thor Thayer <tthayer@opensource.altera.com>

This patch series adds the Altera Arria10 DevKit System Resource
chip's Status and Control Monitor to the A10SR Multi-Function
Device. An earlier patch added this to the hwmon class which
wasn't the proper place so this functionality is added to the
misc directory.
Version 2 changes the DT names from -mon to -monitor for better
readability and clarity and changed the previous version from
modular to built-in.

I reason I preprend a10sr_ is to distinguish this GPIO from the other 
GPIOs when binding to our LEDs (see below). I think the LEDs need a 
unique node name (unless I'm not understanding something).

A less important reason I use a10sr_gpio on the node name is that I can 
cat the /sys/class/gpio/gpioxxx/label and see that it is associated with 
the a10sr instead of one of our other general GPIOs. Is there a better 
way to distinguish these?

The reason I use _ for the node name is that the DTC fails if I 
reference a node name with "-" but works OK for "_". For instance, I get 
an error if the LEDs reference "a10sr-gpio" but "a10sr_gpio" compiles ok.

I reason I preprend a10sr_ is to distinguish this GPIO from the other 
GPIOs when binding to our LEDs (see below). I think the LEDs need a 
unique node name (unless I'm not understanding something).

A less important reason I use a10sr_gpio on the node name is that I can 
cat the /sys/class/gpio/gpioxxx/label and see that it is associated with 
the a10sr instead of one of our other general GPIOs. Is there a better 
way to distinguish these?

The reason I use _ for the node name is that the DTC fails if I 
reference a node name with "-" but works OK for "_". For instance, I get 
an error if the LEDs reference "a10sr-gpio" but "a10sr_gpio" compiles ok.

Thanks for reviewing!

You are confusing DTS labels and node names. Labels are global and
just convenience for the DTS source only instead of using full paths
(and can be anything you want). The node name is local to the level it
is at.

label should come from the label property I think. This is one of the
problems with the GPIO sysfs interface and why it is being replaced
with the char dev interface.

Again, I'm talking node names. You are talking labels. And yes, DTS
labels can't use '-'.
