Subject: Re: [PATCH v3 3/3] ethernet: arc: Add support for specific SoC glue layer device tree bindings

The code changes all look good in this version, but the Kconfig and changelog
are not yet perfect:

Please restrict the changelog line width to something like 70 characters

This should be 'tristate', so you can build it as a loadable module
when ARC_EMAC is also a module. Kconfig will ensure it is set to 'y'
if any other built-in driver selects it, or to 'm' if it is selected
only by drivers that are also modules.

The 'depends on' lines need to be moved below, otherwise you can still
enable ARC_EMAC if OF_IRQ and OF_NET are disabled.
