mscc: ocelot: add support for SerDes muxing configuration
The Ocelot switch has currently an hardcoded SerDes muxing that suits only
a particular use case. Any other board setup will fail to work.
To prepare for upcoming boards' support that do not have the same muxing,
create a PHY driver that will handle all possible cases.
A SerDes can work in SGMII, QSGMII or PCIe and is also muxed to use a
given port depending on the selected mode or board design.
The SerDes configuration is in the middle of an address space (HSIO) that
is used to configure some parts in the MAC controller driver, that is why
we need to use a syscon so that we can write to the same address space from
different drivers safely using regmap.
This breaks backward compatibility but it's fine because there's only one
board at the moment that is using what's modified in this patch series.
This will break git bisect.
Even though this patch series is about SerDes __muxing__ configuration, the
DT node is named serdes for the simple reason that I couldn't find any
mention to SerDes anywhere else from the address space handled by this
driver.
v4:
- add reviewed-by,
- format the patch series with -M for identifying renamed files,
- add parent info in DT binding of the SerDes IP,
- move to macros SERDES[16]G(X) instead of multiple SERDES[16]G_[012345]
constants,
- move to SERDES[16]G_MAX being the last VALID macro of a type, so
migrate to <= conditions instead of < when iterating,
- create a SERDES_MUX_SGMII and SERDES_MUX_QSGMII macro so the muxing
configurations are a tad more readable,
- use a bunch of unsigned int instead of int,
- return -EOPNOTSUPP for SERDES6G/PCIe until it's supported,
- simplify condition when there is an error code returned by
devm_of_phy_get,
v3:
- add Paul Burton's Acked-By on MIPS patches so that the patch series can
be merged in the net tree in its entirety,
v2:
- use a switch case for setting the phy_mode in the SerDes driver as
suggested by Andrew,
- stop replacing the value of the error pointer in the SerDes driver,
- use a dev_dbg for the deferring of the probe in the SerDes driver,
- use constants in the Device Tree to select the SerDes macro in use with
a port,
- adapt the SerDes driver to use those constants,
- add a header file in include/dt-bindings for the constants,
- fix space/tab issue,

Previously, the SerDes muxing was hardcoded to a given mode in the MAC
controller driver. Now, the SerDes muxing is configured within the
Device Tree and is enforced in the MAC controller driver so we can have
a lot of different SerDes configurations.
Make use of the SerDes PHYs in the MAC controller to set up the SerDes
according to the SerDes<->switch port mapping and the communication mode
with the Ethernet PHY.

In commit ec3ed293e7 ("net_sched: change tcf_del_walker() to take idrinfo->lock")
we move fl_hw_destroy_tmplt() to a workqueue to avoid blocking
with the spinlock held. Unfortunately, this causes a lot of
troubles here:
1. tcf_chain_destroy() could be called right after we queue the work
but before the work runs. This is a use-after-free.
2. The chain refcnt is already 0, we can't even just hold it again.
We can check refcnt==1 but it is ugly.
3. The chain with refcnt 0 is still visible in its block, which means
it could be still found and used!
4. The block has a refcnt too, we can't hold it without introducing a
proper API either.
We can make it working but the end result is ugly. Instead of wasting
time on reviewing it, let's just convert the troubling spinlock to
a mutex, which allows us to use non-atomic allocations too.

This traffic scheduler allows traffic classes states (transmission
allowed/not allowed, in the simplest case) to be scheduled, according
to a pre-generated time sequence. This is the basis of the IEEE
802.1Qbv specification.
Example configuration:
tc qdisc replace dev enp3s0 parent root handle 100 taprio \
num_tc 3 \
map 2 2 1 0 2 2 2 2 2 2 2 2 2 2 2 2 \
queues 1@0 1@1 2@2 \
base-time 1528743495910289987 \
sched-entry S 01 300000 \
sched-entry S 02 300000 \
sched-entry S 04 300000 \
clockid CLOCK_TAI
The configuration format is similar to mqprio. The main difference is
the presence of a schedule, built by multiple "sched-entry"
definitions, each entry has the following format:
sched-entry <CMD> <GATE MASK> <INTERVAL>
The only supported <CMD> is "S", which means "SetGateStates",
following the IEEE 802.1Qbv-2015 definition (Table 8-6). <GATE MASK>
is a bitmask where each bit is a associated with a traffic class, so
bit 0 (the least significant bit) being "on" means that traffic class
0 is "active" for that schedule entry. <INTERVAL> is a time duration
in nanoseconds that specifies for how long that state defined by <CMD>
and <GATE MASK> should be held before moving to the next entry.
This schedule is circular, that is, after the last entry is executed
it starts from the first one, indefinitely.
The other parameters can be defined as follows:
- base-time: specifies the instant when the schedule starts, if
'base-time' is a time in the past, the schedule will start at
base-time + (N * cycle-time)
where N is the smallest integer so the resulting time is greater
than "now", and "cycle-time" is the sum of all the intervals of the
entries in the schedule;
- clockid: specifies the reference clock to be used;
The parameters should be similar to what the IEEE 802.1Q family of
specification defines.
