net: dsa: microchip: common spi probe for the ksz series switches - part 2

This patch series aims to refactor the ksz_switch_register routine to have the
common flow for the ksz series switch. And this is the follow up patch series.

First, it tries moves the common implementation in the setup from individual
files to ksz_setup. Then implements the common dsa_switch_ops structure instead
of independent registration. And then moves the ksz_dev_ops to ksz_common.c,
it allows the dynamic detection of which ksz_dev_ops to be used based on
the switch detection function.

Finally, the patch updates the ksz_spi probe function to be same for all the
ksz_switches.

As of now, there are two spi probes, one ksz8795_spi.c and other
ksz9477_spi.c. This patch combines two files into single ksz_spi.c. The
difference between the two are regmap config and struct ksz8. The regmap
config is assigned based on the platform data. And struct ksz8 is left
untouched, as it is used only ksz8795.c. It can be used for all
other switches also in future.

Bonding: add per-port priority support

This patch set add per-port priority for bonding failover re-selection.

The first patch add a new filed for bond_opt_value so we can set slave
value easier. I will update the bond_option_queue_id_set() setting
in later patch.

The second patch add the per-port priority for bonding. I defined
it as s32 to compatible with team prio option, which also use a s32
value.

v3: store slave_dev in bond_opt_value directly to simplify setting
    values for slave.

v2: using the extant bonding options management stuff instead setting
    slave prio in bond_slave_changelink() directly.
====================
Signed-off-by: NDavid S. Miller <davem@davemloft.net>

Add per port priority support for bonding active slave re-selection during
failover. A higher number means higher priority in selection. The primary
slave still has the highest priority. This option also follows the
primary_reselect rules.

This option could only be configured via netlink.

Currently, bond_opt_value are mostly used for bonding option settings. If
we want to set a value for slave, we need to re-alloc a string to store
both slave name and vlaue, like bond_option_queue_id_set() does, which
is complex and dumb.

As Jon suggested, let's add a union field slave_dev for bond_opt_value,
which will be benefit for future slave option setting. In function
__bond_opt_init(), we will always check the extra field and set it
if it's not NULL.

The perout function is used to generate a 1PPS signal, synchronized
to the PHC.  This is accomplished by a using the hardware oneshot
functionality, which is reset by a timer.

The external timestamp function is set up for a 1PPS input pulse,
and uses a timer to poll for temestamps.

Both functions use the SYNC_OUT/SYNC_IN1 pin, so cannot run
simultaneously.
