[PATCH 00/12] Add support for PSE port priority

[Kory Maincent]

From: Kory Maincent (Dent Project) <kory.maincent@xxxxxxxxxxx>

This series brings support for port priority in the PSE subsystem.
PSE controllers can set priorities to decide which ports should be
turned off in case of special events like over-current.

This series also adds support for the devm_pse_irq_helper() helper,
similarly to devm_regulator_irq_helper(), to report events and errors.
Wrappers are used to avoid regulator naming in PSE drivers to prevent
confusion.

Patches 1-3: Cosmetics.
Patch 4: Adds support for last supported features in the TPS23881 drivers.
Patches 5-7: Add support for port priority in PSE core and ethtool.
Patches 8-9: Add support for port priority in PD692x0 and TPS23881 drivers.
Patches 10-11: Add support for devm_pse_irq_helper() helper in PSE core and
               ethtool.
Patch 12: Adds support for interrupt and event report in TPS23881 driver.

This patch series is based on the fix sent recently:
