net: dsa: microchip: Always set regmap stride to 1

2019-10-11T16:36:48+00:00

[ Upstream commit a3aa6e65beebf3780026753ebf39db19f4c92990 ]

The regmap stride is set to 1 for regmap describing 8bit registers already.
However, for 16/32/64bit registers, the stride is 2/4/8 respectively. This
is not correct, as the switch protocol supports unaligned register reads
and writes and the KSZ87xx even uses such unaligned register accesses to
read e.g. MIB counter.

This patch fixes MIB counter access on KSZ87xx.

net: dsa: microchip: fill regmap_config name

2019-08-31T20:19:07+00:00

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!"

The new route handling in ip_mc_finish_output() from 'net' overlapped
with the new support for returning congestion notifications from BPF
programs.

In order to handle this I had to take the dev_loopback_xmit() calls
out of the switch statement.

The aquantia driver conflicts were simple overlapping changes.

net: dsa: microchip: Replace bit RMW with regmap

2019-06-28T02:25:02+00:00

Regmap provides read-modify-write function to update bitfields in
registers. Replace ad-hoc read-modify-write with regmap_update_bits()
where applicable.

net: dsa: microchip: Replace ksz9477_wait_alu_sta_ready polling with regmap

2019-06-28T02:25:02+00:00

Regmap provides polling function to poll for bits in a register. This
function is another reimplementation of polling for bit being clear in
a register. Replace this with regmap polling function. Moreover, inline
the function parameters, as the function is never called with any other
parameter values than this one.
