platform/x86: ISST: Fix return value on last invalid resource

2024-08-20T11:19:09Z

When only the last resource is invalid, tpmi_sst_dev_add() is returing error even if there are other valid resources before. This function should return error when there are no valid resources. Here tpmi_sst_dev_add() is returning "ret" variable. But this "ret" variable contains the failure status of last call to sst_main(), which failed for the invalid resource. But there may be other valid resources before the last entry. To address this, do not update "ret" variable for sst_main() return status. If there are no valid resources, it is already checked for by !inst below the loop and -ENODEV is returned.

platform/surface: aggregator: Fix warning when controller is destroyed in probe

2024-08-13T08:20:19Z

There is a small window in ssam_serial_hub_probe() where the controller is initialized but has not been started yet. Specifically, between ssam_controller_init() and ssam_controller_start(). Any failure in this window, for example caused by a failure of serdev_device_open(), currently results in an incorrect warning being emitted. In particular, any failure in this window results in the controller being destroyed via ssam_controller_destroy(). This function checks the state of the controller and, in an attempt to validate that the controller has been cleanly shut down before we try and deallocate any resources, emits a warning if that state is not SSAM_CONTROLLER_STOPPED. However, since we have only just initialized the controller and have not yet started it, its state is SSAM_CONTROLLER_INITIALIZED. Note that this is the only point at which the controller has this state, as it will change after we start the controller with ssam_controller_start() and never revert back. Further, at this point no communication has taken place and the sender and receiver threads have not been started yet (and we may not even have an open serdev device either). Therefore, it is perfectly safe to call ssam_controller_destroy() with a state of SSAM_CONTROLLER_INITIALIZED. This, however, means that the warning currently being emitted is incorrect. Fix it by extending the check.

platform/surface: aggregator_registry: Add support for Surface Laptop 6

2024-08-13T08:01:20Z

Add SAM client device nodes for the Surface Laptop Studio 6 (SL6). The SL6 is similar to the SL5, with the typical battery/AC, platform profile, and HID nodes. It also has support for the newly supported fan interface.

Add SAM client device nodes for the Surface Laptop Studio 2 (SLS2). The SLS2 is quite similar to the SLS1, but it does not provide the touchpad as a SAM-HID device. Therefore, add a new node group for the SLS2 and update the comments accordingly. In addition, it uses the new fan control interface.

The new ROG Ally X functions the same as the previus model so we can use the same method to ensure the MCU USB devices wake and reconnect correctly. Given that two devices marks the start of a trend, this patch also adds a quirk table to make future additions easier if the MCU is the same. Signed-off-by: Luke D.
