phy: core: add debugfs files

2023-05-19T17:53:52+00:00

Add a debugfs root for phy class, and create a debugfs directory under the root when create phy, then phy drivers can add debugfs files. Signed-off-by: Chunfeng Yun Link: https://lore.kernel.org/r/20230513092218.21139-1-chunfeng.yun@mediatek.com Signed-off-by: Vinod Koul

phy: Add devm_of_phy_optional_get() helper

2023-02-03T05:22:49+00:00

Add an optional variant of devm_of_phy_get() that also takes care of printing real errors, so drivers no longer have to open-code this operation.

phy: Remove unused phy_optional_get()

2023-02-03T05:22:49+00:00

There were never any upstream users of this function since its introduction almost 10 years ago. Besides, the dummy for phy_optional_get() should have returned NULL instead of an error code.

phy: Add LVDS configuration options

2022-04-20T07:29:50+00:00

This patch allows LVDS PHYs to be configured through the generic functions and through a custom structure added to the generic union. The parameters added here are based on common LVDS PHY implementation practices. The set of parameters should cover all potential users.

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 media type and speed serdes configuration interfaces

2021-03-17T06:43:19+00:00

Provide new phy configuration interfaces for media type and speed that allows e.g. PHYs used for ethernet to be configured with this information.

phy: Add new PHY attribute max_link_rate

2020-09-16T12:08:02+00:00

Add new PHY attribute max_link_rate to struct phy_attrs. This indicates maximum link rate supported by PHY (in Mbps).

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. Signed-off-by: Yuti Amonkar Reviewed-by: Maxime Ripard Reviewed-by: Jyri Sarha Signed-off-by: Kishon Vijay Abraham I

phy: core: Add consumer device link support

In order to enforce suspend/resume ordering, this commit creates link between phy consumers and phy devices. This link avoids to suspend phy before phy consumers.
