phy: ti: phy-omap-usb2: Fix NULL pointer dereference for SRP

2024-01-30T17:11:11Z

If the external phy working together with phy-omap-usb2 does not implement send_srp(), we may still attempt to call it. This can happen on an idle Ethernet gadget triggering a wakeup for example: configfs-gadget.g1 gadget.0: ECM Suspend configfs-gadget.g1 gadget.0: Port suspended. Triggering wakeup ...

phy: ti: gmii-sel: Fix register offset when parent is not a syscon node

2023-11-16T11:27:50Z

When the node for this phy selector is a child node of a syscon node then the property 'reg' is used as an offset into the parent regmap. When the node is standalone and gets its own regmap this offset is pre-applied. So we need to track which method was used to get the regmap and not apply the offset in the standalone case.

phy: Drop unnecessary of_match_device() calls

2023-10-13T10:17:53Z

If probe is reached, we've already matched the device and in the case of DT matching, the struct device_node pointer will be set. Therefore, there is no need to call of_match_device() in probe.

phy: Explicitly include correct DT includes

2023-07-17T06:22:56Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

phy: ti: gmii-sel: Allow parent to not be syscon node

2023-07-14T12:54:31Z

If the parent node is not a syscon type, then fallback and check if we can get a regmap from our own node. This no longer forces us to make the parent of this node a syscon node when that might not be appropriate.
