The Fully-Programmable Input/Output Array (FPIOA) device controls pin
multiplexing on the K210. The FPIOA can remap any supported function to any
multifunctional IO pin. It can also perform basic GPIO functions, such as
reading the current value of a pin. However, GPIO functionality remains
largely unimplemented (in favor of the dedicated GPIO peripherals).

This normalizes the documentation to conform to kernel-doc style [1]. It
also moves the documentation for pinctrl_ops inline, and adds argument and
return-value documentation. I have kept the usual function style for these
comments. I could not find any existing examples of function documentation
inside structs.

The pinmux property allows for smaller and more compact device trees,
especially when there are many pins which need to be assigned individually.
Instead of specifying an array of strings to be parsed as pins and a
function property, the pinmux property contains an array of integers
representing pinmux groups. A pinmux group consists of the pin identifier
and mux settings represented as a single integer or an array of integers.
Each individual pin controller driver specifies the exact format of a
pinmux group. As specified in the Linux documentation, a pinmux group may
be multiple integers long. However, no existing drivers use multi-integer
pinmux groups, so I have chosen to omit this feature. This makes the
implementation easier, since there is no need to allocate a buffer to do
endian conversions.
Support for the pinmux property is done differently than in Linux. As far
as I can tell, inversion of control is used when implementing support for
the pins and groups properties to avoid allocating. This results in some
duplication of effort; every property in a config node is parsed once for
each pin in that node. This is not such an overhead with pins and groups
properties, since having multiple pins in one config node does not occur
especially often. However, the semantics of the pinmux property make such a
configuration much more appealing. A future patch could parse all config
properties at once and store them in an array. This would make it easier to
create drivers which do not function solely as callbacks from
pinctrl-generic.
This commit increases the size of the sandbox build by approximately 48
bytes. However, it also decreases the size of the K210 device tree by 2
KiB from the previous version of this series.
The documentation has been updated from the last Linux commit before it was
split off into yaml files.

The VIM3 on-board MCU can mux the PCIe/USB3.0 shared differential
lines using a FUSB340TMX USB 3.1 SuperSpeed Data Switch between
an USB3.0 Type A connector and a M.2 Key M slot.
The PHY driving these differential lines is shared between
the USB3.0 controller and the PCIe Controller, thus only
a single controller can use it.
This adds this dynamic switching right before booting Linux
and the configuration steps in the boards documentation.

- I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
because using drivers/net/fsl_mdio.c leads in none existent
udevice mdio@3320
instead boards with DM ETH support should use now this
driver.
- remove RFC tag
Commit-notes:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This Code should be removed if all boards are converted
to DM/DTS.
- add the DM based qe uec driver under drivers/net/qe
- Therefore copied the files uccf.c uccf.h uec.h from
drivers/qe. So there are a lot of Codingstyle problems
currently. I fix them in next version if this RFC
patch is OK or it needs some changes.
- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
Used a lot of functions from drivers/qe/uec.c
- seperated the PHY specific code into seperate file

- s5p4418_nanopi2.h: "CONFIG_" removed from several s5p4418/nanopi2
specific defines because the appropriate values do not need to be
