[PATCH net-next 0/2] net: ethernet: renesas: infrastructure preparations for upcoming driver

[PATCH net-next 0/2] net: ethernet: renesas: infrastructure preparations for upcoming driver

[Wolfram Sang]

Before we upstream a new driver, Niklas and I thought that a few
cleanups for Kconfig/Makefile will help readability and maintainability.
Here they are, looking forward to comments.

[PATCH net-next 1/2] net: ethernet: renesas: group entries in Makefile

[Wolfram Sang]

A new Renesas driver shall be added soon. Prepare the Makefile by
grouping the specific objects to the Kconfig symbol for better
readability. Improve the file description a tad while here.

[PATCH net-next 2/2] net: ethernet: renesas: drop SoC names in Kconfig

[Wolfram Sang]

Mentioning SoCs in Kconfig descriptions tends to get stale (e.g. RAVB is
missing RZV2M) or imprecise (e.g. SH_ETH is not available on all
R8A779x). Drop them instead of providing vague information. Improve the
file description a tad while here.

It's not a big deal, but assuming that keeping the SoC list up2date
requires too much effort, I would still keep it, with some additional
wording specifying it's partial and potentially inaccurate.

Such list could be an useful starting point for an integrator looking
for the correct driver for his/her SoC.

Cheers,

Paolo

Apparently it was too much effort...

For modern DT-based systems, it's much easier to look up compatible
values.
