net: pcs: altera-tse: don't set the speed for 1000BaseX

2022-11-30T04:29:55+00:00

When disabling the SGMII mode bit, the PCS defaults to 1000BaseX mode.
In that mode, we don't need to set the speed since it's always 1000Mbps.

net: pcs: altera-tse: use read_poll_timeout to wait for reset

2022-11-30T04:29:55+00:00

Software resets on the TSE PCS don't clear registers, but rather reset
all internal state machines regarding AN, comma detection and
encoding/decoding. Use read_poll_timeout to wait for the reset to clear
instead of manually polling the register.

net: pcs: add new PCS driver for altera TSE PCS

2022-09-05T09:16:53+00:00

The Altera Triple Speed Ethernet has a SGMII/1000BaseC PCS that can be
integrated in several ways. It can either be part of the TSE MAC's
address space, accessed through 32 bits accesses on the mapped mdio
device 0, or through a dedicated 16 bits register set.

This driver allows using the TSE PCS outside of altera TSE's driver,
since it can be used standalone by other MACs.

net: pcs: xpcs: propagate xpcs_read error to xpcs_get_state_c37_sgmii

2022-07-22T02:01:16+00:00

While phylink_pcs_ops :: pcs_get_state does return void, xpcs_get_state()
does check for a non-zero return code from xpcs_get_state_c37_sgmii()
and prints that as a message to the kernel log.

However, a non-zero return code from xpcs_read() is translated into
"return false" (i.e. zero as int) and the I/O error is therefore not
printed. Fix that.
