    kernel: 5.10: backport qca8k new feature
    
    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.

+
+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.

+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.

+From ba8f870dfa635113ce6e8095a5eb1835ecde2e9e Mon Sep 17 00:00:00 2001

+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.
