net: phy: c45 baset1: do not skip aneg configuration if clock role is not specified

2022-08-09T03:54:28+00:00

In case master/slave clock role is not specified (which is default), the aneg registers will not be written. The visible impact of this is missing pause advertisement. So, rework genphy_c45_baset1_an_config_aneg() to be able to write advertisement registers even if clock role is unknown.

net: phy: Add 10BASE-T1L support in phy-c45

2022-05-01T16:45:35+00:00

This patch is needed because the BASE-T1 uses different registers for status, control and advertisement to those already employed in the existing phy-c45 functions. Where required, genphy_c45 functions will now check whether the device supports BASE-T1 and use the specific registers instead: 45.2.7.19 BASE-T1 AN control register, 45.2.7.20 BASE-T1 AN status, 45.2.7.21 BASE-T1 AN advertisement register, 45.2.7.22 BASE-T1 AN LP Base Page ability register, 45.2.1.185 BASE-T1 PMA/PMD control register.
