Add pending patches which add a PSE driver for the PSE setup found on
most of Realtek-based switches. An MCU with a Realtek-defined firmware
and protocol fronts one or more PSE chips (from Realtek or Broadcom) as
a management controller.
The driver provides both I2C/SMBus and UART communication, which varies
among our supported switches. There is no need for complicated userspace
handling anymore, the PSE setup is defined in the device tree and
interfaced in userspace via ethtool, netlink and netifd support.
Those patches have progressed far enough upstream, the bindings are
reviewed. Thus, we can keep this intermediate version downstream to open
it up earlier for usage. Only little changes are expected til the final
version lands.
