e7c5e08db0 kernel: ar8216: add get_features method
Modifying PHY capabilities in the probe function broke with upstream
commit 92ed2eb7f4b7 ("net: phy: probe the PHY before determining the
supported features").

AR8316 switches only support 10/100 Mbit/s link modes because of this
change.

Provide a get_features method for the PHY driver, so Gigabit link mode
will be advertised to link partners again.

47f17b0662 generic: ar8216: fix unknown packet flooding for ar8229/ar8236
ar8229 and ar8236 don't allow unknown unicast/multicast frames and
broadcast frames to be flooded to cpu port. This isn't desired behavior
for swconfig as we treat it as a standalone switch.
Current code doesn't enable unicast frame flooding for ar8229 and uses
wrong setup for ar8236. This commit fixes both of them by enabling port
0 flooding for all unknown frames.

3f79aaa297 generic ar8xxx: increase VLAN table for AR83x7
The Atheros AR8327 and AR8337 have (according to their datasheet) a
VLAN table with a maximum of 4096 entries.

Currently, there's a hard limit of 128 VLANs, which is the same as
for most other Atheros switches. Increase this limit only for the
AR83x7 series and modify some shared functions to allow them to work
with a variable max VLAN count.

01c0d7f86f generic: ar8216: group MIB counters and use two basic ones only by default
There are too many MIB counters that almost nobody needs since commit
d6366ce366 ("generic: ar8216: mib_work_func: read all port mibs
everytime").

In the worker function to poll MIB data, it deals with all ports instead
of only one port every time, which introduces too many mdio operations
that it becomes a heavy CPU load even on not-emulated MDIO bus.

This commit groups MIB counters and enable only TxBytes and RxGoodBytes
by default (both of which are necessary to get swconfig led working.)
and adds an swconfig attribute to allow enabling all counters if users
need them.

LEDs can enable them with qca,mib-poll-interval dts property or with

c8c2ef1d49 generic: ar8216: do a software reset for switch during hw_init
This applies to ar8216 and ar8236. QCA's newer U-boot will enable
the switch mdio master for FE switches which makes phy inaccessible
from CPU mdio. (e.g. on TP-Link TL-WR941N v7 Chinese version which
uses QCA9558+AR8236.) For these devices PHY probing is broken and
mdio device probing is a must. We also need to disable switch mdio
master in driver for later PHY initialization.

Do a soft reset during hw_init so that mdio master can be disabled
and expose PHYs to CPU mdio for later PHY accessing.

9fc506e9b2 generic: ar8216: add support for get_port_stats()
Partially reverts commit eff3549c58.

AR7240 and AR9341 have buggy hardware switch LED trigger. The AR7240
one doesn't blink and the blinking of port0/port5 is reversed on
AR9341 if we swap PHY0 and PHY4. (Only blinking is reversed, which
means LED for PHY0 will lit when PHY0 is link up and will blink when
PHY4 has active link and vice versa.) On these two chips a software
swconfig LED trigger is required.

This commit adds swconfig port stats back but:
 1. move checking of mib_t/rxb_id into ar8xxx_chip since we can't
    distinguish ar7240sw and ar8216 using only chip id.
 2. don't update mib counter in get_port_stat. This function is called
    every 0.01s and this capturing procedure will take up a lot of CPU.
    We already have a mib_work_func updating mib counters every 2s so
    return the saved counter instead of fetching new data. The blinking
    rate will be weird but it should solve the previously mentioned CPU
    time problem.

0598ec0abc generic: ar8216: add support for ar724x/ar933x builtin switch
This builtin switch is a bugless ar8216 with different mib counters

Atheros uses the same device ID and it's impossible to distinguish

Atheros FE switches have a builtin mdio master available for PHY

ar8229 is the builtin switch in ar934x and later chips. There is

This commit added support for the builtin ar8229. The only thing

Only add its support for mdio-device probing method because the

CHROMIUM: drivers: ar8216: prevent device duplication in ar8xxx_dev_list

If probe is called twice, once for PHY0 and a second time for PHY4,
the same switch device will be added twice to ar8xxx_dev_list, while
supposedly this list should have one element per hardware switch present
in the system.

While no negative impact have been observed, it does happen if a
platform instanciates these two PHYs from device-tree, as an example.

CHROMIUM: drivers: ar8216: sync mib_work cancellation

ar8xxx_mib_stop() is called from ar8xxx_phy_remove(), so we want to make
sure the work doesn't run after priv is freed / the device ceases to
exist.

e9455c561d generic: ar8216: improve ar8xxx_is_possible check
The commit "generic: ar8216: add sanity check to ar8216_probe"
(774da6c7a4) stated that PHY IDs
should be checked at address 0-4. However, the PHY 4 was
never check by the loop. This patch extends the check to be
similar to the Atheors SDK. It tries all 4 ports and skips
unconnected PHYs if necessary. If it cannot find any familiar
PHYs, it will prevent the phy driver from initializing.

This patch is necessary for the C-60. It doesn't have a
PHY at port 3, so this caused the check in ar8xxx_is_possible
to fail. As a result, the ethernet ports on the C-60 didn't
work.

3a03c08c82 AR8216: improve mmd register access
Combine all bus operations for one MMD access in one function.
Protecting all these bus operations with one lock also helps
to avoid potential issues due to bus operations intercepting
the register and data write.

d3776bdfc9 AR8216: make ARL age time configurable
The default TTL for address resolution table entries is 5 minutes
for all members of the AR8216 family. This can cause issues if
e.g. Wifi clients roam to another AP and their MAC appears on
another switch port suddenly. Then the client may not be reachable
until the old ARL entry expires.
I would have expected the switch to invalidate old entries if it
detects the same MAC on another port. But that's not the case.

Therefore make the TTL for ARL entries configurable.
The effective TTL will always be a multiple of 7 seconds.

76e1efc042 AR8216: don't display MIB counters if all are empty
For unused switch ports all MIB values are zero. Displaying ~40 empty
MIB counters is just confusing and makes it hard to read the output of
swconfig dev <dev> show.
Therefore, if all MIB counters for a port are zero, just display
an info that the MIB counters are empty.

00e599b0b7 ar8216: add ARL table flushing per port
Adds functions for flushing ARL table entries per port.

Successfully tested on AR8327. Implementation for AR8216/AR8236/AR8316
is based on the AR8236 datasheet and assumes that the three chips
share a common ATU register layout.
Compile-tested only for AR8216/AR8236/AR8316.

2666403c3a ar8216: add reading ARL table for AR8216/AR8236/AR8316
Adds the chip-specific part of reading ARL table for AR8216/AR8236/AR8316.

It's based on the AR8236 datasheet and compile-tested only as I couldn't
find datasheets for AR8216/AR8316 and don't own devices with these chips.

The existing ar8216_atu_flush implementation was used for all three
chip types, therefore I guess they share a common ATU register layout.

More testing would be appreciated.

Add global read-only swconfig attribute "arl_table" to display the

So far the chip-specific part is implemented for AR8327/AR8337 only
as I don't have the datasheets for the other AR8XXX chips.

6ce848f622 ar8216: decrease page switch wait time
Until a few years ago the page switch wait time was set to msleep(1)
what was changed to usleep_range(1000, 2000) later.

I can not imagine that a low-level operation like switching page
on register level takes so much time.
Most likely the value of 1ms was initially set to check whether
it fixes an issue and then remained w/o further checking whether
also a smaller value would be sufficient.

Now the wait time is set to 5us and I successfully tested this on
AR8327. IMHO 5us should be plenty of time for all supported chips.
However I couldn't test this due to missing hardware.

If other chips should need a longer wait time we can add the
wait time as a parameter to the ar8xxx_chip struct.

74146c62c0 ar8216: fix ATU flushing
The functionality to flush the address translation table contains two bugs
which luckily compensate each other.
1. Just setting the operation is not sufficient to perform the flushing.
   The "active" bit needs to be set to actually trigger an action.
   For the vtu operations this is implemented correctly.
2. ar8xxx_phy_read_status is called every 2s by the phy state machine
   to check for link changes. This would have caused an ATU flush
   every 2s.

Fix the chip-specific ATU flush functions and remove the ATU flush call
from ar8xxx_phy_read_status.
