Subject: [PATCH net-next v3 00/12] Add TJA1120 support

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 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
