Bluetooth: btintel: Combine setting up MSFT extension

2021-08-05T14:03:30+00:00

This patch combines the setting up MSFT extension for the legacy and TLV based bootloader into the common function based on hw_variant. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Fix the legacy bootloader returns tlv based version

2021-08-05T14:03:30+00:00

From the ThP, it supports both legacy and TLV based HCI_Intel_Read_Version command after downloading the operational firmware, and it causes the driver to choose the wrong setup routines and missing firmware/ddc file. So, as a workaround, this patch checks the fw variant from the TLV based version, and if the device is legacy bootloader device, the legacy HCI_Intel_Read_Version command is used to get the legacy version information and run the legacy bootloader setup with it.

Bluetooth: btintel: Refactoring setup routine for bootloader devices

2021-08-05T14:03:29+00:00

This patch refactors the setup routines for legacy and TLV based bootloader devices to the combined setup, and move the related functions from btusb to btintel. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Add combined set_diag functions

2021-08-05T14:03:29+00:00

This patch adds a combined set_diag functions. It also changes the btintel_set_diag_mfg() to static since it is no longer used by others. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Fix the LED is not turning off immediately

2021-08-05T14:03:29+00:00

Some platforms have an issue with BT LED when the interface is down or BT radio is turned off, which takes 5 seconds to BT LED goes off. This command turns off the BT LED immediately. This patch sends the Intel vendor command to turn off the LED. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Fix the first HCI command not work with ROM device

2021-08-05T14:03:29+00:00

The some legacy ROM controllers have a bug with the first HCI command sent to it returning number of completed commands as zero, which would stall the command processing in the Bluetooth core. As a workaround, send HCI Rest command first which will reset the controller to fix the issue. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann

Bluetooth: btintel: Refactoring setup routine for legacy ROM sku

Bluetooth: btintel: Add combined setup and shutdown functions

2021-08-05T14:03:29+00:00

There are multiple setup and shutdown functions for Intel device and the setup function to be used is depends on the USB PID/VID, which makes difficult to maintain the code and increases the code size. This patch adds combined setup and shutdown functions to provide a single entry point for all Intel devices and choose the setup functions based on the information read with HCI_Intel_Read_Version command. Starting from TyP device, the command and response parameters for HCI_Intel_Read_Version command are changed even though OCF remains same. However, the legacy devices still can handle the command without error even if it has a extra parameter, so to simplify the flow, the new command format is used to read the version information for both legacy and new (tlv based) format. Also, it also adds a routine to setup the hdev callbacks in btintel. Signed-off-by: Tedd Ho-Jeong An Signed-off-by: Marcel Holtmann
