Browse Source 
Backport qca8k new feature:
- Ageing configuration support
- Add 2 missing counter on qca8337
- Convert to regmap
- Standardize define and code with GENMASK AND BITFILED macro
- Add mdb add/del support

Subject: regmap: allow to define reg_update_bits for no bus configuration
Some device requires a special handling for reg_update_bits and can't use
the normal regmap read write logic. An example is when locking is
handled by the device and rmw operations requires to do atomic operations.
Allow to declare a dedicated function in regmap_config for
reg_update_bits in no bus configuration.

Subject: net: dsa: qca8k: convert to GENMASK/FIELD_PREP/FIELD_GET
Convert and try to standardize bit fields using
GENMASK/FIELD_PREP/FIELD_GET macros. Rework some logic to support the
standard macro and tidy things up. No functional change intended.

Subject: net: dsa: qca8k: initial conversion to regmap helper
Convert any qca8k set/clear/pool to regmap helper and add
missing config to regmap_config struct.
Read/write/rmw operation are reworked to use the regmap helper
internally to keep the delta of this patch low. These additional
function will then be dropped when the code split will be proposed.
Ipq40xx SoC have the internal switch based on the qca8k regmap but use
mmio for read/write/rmw operation instead of mdio.
In preparation for the support of this internal switch, convert the
driver to regmap API to later split the driver to common and specific
code. The overhead introduced by the use of regamp API is marginal as the
internal mdio will bypass it by using its direct access and regmap will be
used only by configuration functions or fdb access.

Subject: net: dsa: qca8k: add additional MIB counter and make it dynamic
We are currently missing 2 additionals MIB counter present in QCA833x
switch.
QC832x switch have 39 MIB counter and QCA833X have 41 MIB counter.
Add the additional MIB counter and rework the MIB function to print the
correct supported counter from the match_data struct.

Subject: net: dsa: qca8k: add set_ageing_time support
qca8k support setting ageing time in step of 7s. Add support for it and
set the max value accepted of 7645m.
Documentation talks about support for 10000m but that values doesn't
make sense as the value doesn't match the max value in the reg.

Subject: net: dsa: qca8k: add support for mdb_add/del
Add support for mdb add/del function. The ARL table is used to insert
the rule. The rule will be searched, deleted and reinserted with the
port mask updated. The function will check if the rule has to be updated
or insert directly with no deletion of the old rule.
If every port is removed from the port mask, the rule is removed.
The rule is set STATIC in the ARL table (aka it doesn't age) to not be
flushed by fast age function.
