phy: core: Reword the comment specifying the units of max_link_rate to be Mbps

2021-06-14T05:50:17+00:00

In some subsystems (eg. CAN, SPI), the max link rate supported can be less
than 1 Mbps and if the unit for max_link_rate is Mbps then it can't be
used. Therefore, leave the decision of units to be used, to the producer
and consumer.

phy: Add DisplayPort configuration options

2020-01-14T05:20:19+00:00

Allow DisplayPort PHYs to be configured through the generic
functions through a custom structure added to the generic union.
The configuration structure is used for reconfiguration of
DisplayPort PHYs during link training operation.

The parameters added here are the ones defined in the DisplayPort
spec v1.4 which include link rate, number of lanes, voltage swing
and pre-emphasis.

Add the DisplayPort phy mode to the generic phy_mode enum.

phy: fix build breakage: add PHY_MODE_SATA

2019-01-13T05:07:14+00:00

Commit 49e54187ae0b ("ata: libahci_platform: comply to PHY framework") uses
the PHY_MODE_SATA, but that enum had not yet been added. This caused a
build failure for me, with today's linux.git.

Also, there is a potentially conflicting (mis-named) PHY_MODE_SATA, hiding
in the Marvell Berlin SATA PHY driver.

Fix the build by:

    1) Renaming Marvell's defined value to a more scoped name,
       in order to avoid any potential conflicts: PHY_BERLIN_MODE_SATA.

    2) Adding the missing enum, which was going to be added anyway as part
       of [1].
