[PATCH net-next 00/19] net: ethernet: ti: clean up and optimizations

Hi All,

This is a preparation series for introducing new switchbase TI CPSW driver which
was originally introduced [1][2] by Ilias Apalodimas <ilias.apalodimas@linaro.org>
and also discussed in private mails and at Netdev x13 confernce.

Following discussions and suggestions (mostly by Andrew and Ivan) we going
to introduce the new driver which is operating in dual-emac mode
by default, thus working as 2 individual network interfaces.
When both interfaces joined the bridge - CPSW driver will enter a switch
mode and discard dual_mac configuration. The CPSW will be switched back
to dual_mac mode if any port leaves the bridge. All configuration is going to be
implemented via switchdev API.

Hence overall change is already very big I'm sending prerequisite patches which
are mostly minor fixes/clean ups and code refactoring to separate common parts
to be reused by both drivers.
Probably the most serious change from functional point of view is Patch 11.

These patches were NFS boot tetested on TI AM335x/AM437x/AM5xx boards.

These patches can be found at:
git@git.ti.com:~gragst/ti-linux-kernel/gragsts-ti-linux-kernel.git
branch: lkml-5.1-cpsw-clean-up

Functional new cpsw_switch driver (still fighting with few issues) can be found:
git@git.ti.com:~gragst/ti-linux-kernel/gragsts-ti-linux-kernel.git
branch: lkml-5.1-switch-tbd
