| * net: dsa: microchip: fill regmap_config nameGeorge McCollister2019-08-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | Use the register value width as the regmap_config name to prevent the following error when the second and third regmap_configs are initialized. "debugfs: Directory '${bus-id}' with parent 'regmap' already present!" Signed-off-by: George McCollister <[email protected]> Reviewed-by: Marek Vasut <[email protected]> Signed-off-by: David S.

W=1 drivers/net/dsa/microchip/ksz_common.c:23:6: warning: no previous prototype for ‘...’ [-Wmissing-prototypes] Note that the order of the headers cannot be swapped, as that would trigger missing forward declaration errors, which would indicate the way forward is to merge the two headers into one.

* net: dsa: microchip: Factor out regmap config generation into common headerMarek Vasut2019-06-271-0/+32
| | | | | | | | | | | | | | The regmap config tables are rather similar for various generations of the KSZ8xxx/KSZ9xxx switches. Introduce a macro which allows generating those tables without duplication. Note that $regalign parameter is not used right now, but will be used in KSZ87xx series switches.

* net: dsa: microchip: Dispose of ksz_io_opsMarek Vasut2019-06-271-36/+14
| | | | | | | | | | | | | Since the driver now uses regmap , get rid of ad-hoc ksz_io_ops abstraction, which no longer has any meaning. Moreover, since regmap has it's own locking, get rid of the register access mutex.

| | | | | | | | | | | | | Add background MIB counter reading support. Port MIB counters should only be read when there is link. Otherwise it is a waste of time as hardware never increases those counters. There are exceptions as some switches keep track of dropped counts no matter what.

Break KSZ9477 DSA driver into two files in preparation to add more KSZ switch drivers. Add common functions in ksz_common.h so that other KSZ switch drivers can access code in ksz_common.c.
