[PATCH net-next v4 00/11] Add TJA1120 support

[PATCH net-next v4 00/11] Add TJA1120 support

[Radu Pirea (NXP OSS)]

Hello everyone,

This patch series got bigger than I expected. It cleans up the
next-c45-tja11xx driver and adds support for the TJA1120(1000BaseT1
automotive phy).

Master/slave custom implementation was replaced with the generic
implementation (genphy_c45_config_aneg/genphy_c45_read_status).

The TJA1120 and TJA1103 are a bit different when it comes to the PTP
interface. The timestamp read procedure was changed, some addresses were
changed and some bits were moved from one register to another. Adding
TJA1120 support was tricky, and I tried not to duplicate the code. If
something looks too hacky to you, I am open to suggestions.

Cheers,
Radu P

Changes in v4:
- rebased on top of net-next/main
- dropped "net: phy: c45: detect 100BaseT1 and 1000BaseT1 PMA abilites".
 Already part of upstream.

Changes in v3:
- merged "net: phy: nxp-c45-tja11xx: add *_reg_field functions" in
 "net: phy: nxp-c45-tja11xx: prepare the ground for TJA1120"
- rephrased the commit message for "net: phy: nxp-c45-tja11xx: remove RX
 BIST frame counters"

Changes in v2:
- dropped "net: phy: nxp-c45-tja11xx: fix the PTP interrupt
 enablig/disabling"
- added error msgs to nxp_c45_set_reg_field and nxp_c45_clear_reg_field
- used phy_err instead of phy_warn in nxp_c45_write_reg_field and
 nxp_c45_read_reg_field
- removed null checks for .driver_data and its fields
- added 100BT1 and 1000BT1 features bit
- replaced .features with .get_features
- dropped changed on TJA1103 EXT TS behaviour
- improved timestamp reading workarounds
- merged patch "net: phy: nxp-c45-tja11xx: timestamp reading workaround for
 TJA1120" to 9 and 12
- implemented PCS reset workaround in link_change_notify callback

[PATCH net-next v4 01/11] net: phy: nxp-c45-tja11xx: use phylib master/slave implementation

[Radu Pirea (NXP OSS)]

Remove the custom implementation of master/save setup and read status
and use genphy_c45_config_aneg and genphy_c45_read_status since phylib
has support for master/slave setup and master/slave status.

[PATCH net-next v4 03/11] net: phy: nxp-c45-tja11xx: prepare the ground for TJA1120

[Radu Pirea (NXP OSS)]

Between TJA1120 and TJA1103 the hardware was improved, but some register
addresses were changed and some bit fields were moved from one register
to another.

Introduce the nxp_c45_reg_field structure and its associated functions to
abstract the differences between the PHYs.

Remove the defined bits and register addresses that are not common
between TJA1103 and TJA1120 and replace them with reg_fields and
register addresses from phydev->drv->driver_data.

[PATCH net-next v4 04/11] net: phy: nxp-c45-tja11xx: use get_features

[Radu Pirea (NXP OSS)]

PHY_BASIC_T1_FEATURES are not the right features supported by TJA1103
anymore.
For example ethtool reports:
	[root@alarm ~]# ethtool end0
	Settings for end0:
	        Supported ports: [ TP ]
	        Supported link modes:   100baseT1/Full
	                                10baseT1L/Full

10baseT1L/Full is not supported by TJA1103 and supported ports list is
not completed. The PHY also have a MII port.

genphy_c45_pma_read_abilities implementation can detect the PHY features
and they look like this.
[root@alarm ~]# ethtool end0
Settings for end0:
        Supported ports: [ TP    MII ]
        Supported link modes:   100baseT1/Full
        Supported pause frame use: Symmetric
        Supports auto-negotiation: No
        Supported FEC modes: Not reported
        Advertised link modes:  100baseT1/Full
        Advertised pause frame use: Symmetric
        Advertised auto-negotiation: No
        Advertised FEC modes: Not reported
        Speed: 100Mb/s
        Duplex: Full
        Auto-negotiation: off
        master-slave cfg: forced master
        master-slave status: master
        Port: Twisted Pair
        PHYAD: 1
        Transceiver: external
        MDI-X: Unknown
        Supports Wake-on: g
        Wake-on: d
        Link detected: yes
        SQI: 7/7

[PATCH net-next v4 06/11] net: phy: nxp-c45-tja11xx: enable LTC sampling on both ext_ts edges

[Radu Pirea (NXP OSS)]

The external trigger configuration for TJA1120 has changed. The PHY
supports sampling of the LTC on rising and on falling edge.

[PATCH net-next v4 07/11] net: phy: nxp-c45-tja11xx: read egress ts on TJA1120

[Radu Pirea (NXP OSS)]

The egress timestamp FIFO/circular buffer work different on TJA1120 than
TJA1103.

For TJA1103 the new timestamp should be manually moved from the FIFO to
the hardware buffer before checking if the timestamp is valid.

For TJA1120 the hardware will move automatically the new timestamp
from the FIFO to the buffer and the user should check the valid bit, read
the timestamp and unlock the buffer by writing any of the buffer
registers(which are read only).

Another change for the TJA1120 is the behaviour of the EGR TS IRQ bit.
This bit was a self-clear bit for TJA1103, but now should be cleared
before reading the timestamp.

[PATCH net-next v4 08/11] net: phy: nxp-c45-tja11xx: handle FUSA irq

[Radu Pirea (NXP OSS)]

TJA1120 and TJA1103 have a set of functional safety hardware tests
executed after every reset, and when the tests are done, the IRQ line is
asserted. For the moment, the purpose of these handlers is to acknowledge
the IRQ and not to check the FUSA tests status.

[PATCH net-next v4 10/11] net: phy: nxp-c45-tja11xx: read ext trig ts on TJA1120

[Radu Pirea (NXP OSS)]

On TJA1120, the external trigger timestamp now has a VALID bit. This
changes the logic and we can't use the TJA1103 procedure.

For TJA1103, we can always read a valid timestamp from the registers,
compare the new timestamp with the old timestamp and, if they are not the
same, an event occurred. This logic cannot be applied for TJA1120 because
the timestamp is 0 if the VALID bit is not set.

[PATCH net-next v4 11/11] net: phy: nxp-c45-tja11xx: reset PCS if the link goes down

[Radu Pirea (NXP OSS)]

During PTP testing on early TJA1120 engineering samples I observed that
if the link is lost and recovered, the tx timestamps will be randomly
lost. To avoid this HW issue, the PCS should be reseted.

Resetting the PCS will break the link and we should reset the PCS on
LINK UP -> LINK DOWN transition, otherwise we will trigger and infinite
loop of LINK UP -> LINK DOWN events.
