[PATCH v2 00/16] realtek: pinctrl and switch LED drivers

[Sander Vanheule]

Revised patch set of an earlier RFC, introducing an MFD driver for the
switch core, and dependent pinctrl and LED drivers. This should allow
users to control the switch port LED to their liking, and make it easier
to configure pin muxes. System LED support is also provided, although
not enabled.

Since the RFC, support for Cypress (RTL835x/RTL839x) as added, in
addition to the already suggested Maple support (RTL833x/RTL838x).

The system LED driver was split of from the core MFD driver, and some
shared logic with the switch port LED driver was put into a separate
unit.

As make-shift documentation to the devicetree interfaces, the
corresponding nodes changes are also implemented, including LED support
for the Zyxel GS1900-8 an GS1900-48 switches.

In addition to driver changes, this patch series also includes a
non-code patch introducing a target TODO file.
