Hi Marcel and Loïc,

This is already partially supported in the hci_bcm driver.
Today this driver registers a platform_driver(legacy/ACPI) and a
serdev_device_driver (new/DT).
The platform driver retrieves the gpios and mainly uses them in pm ops.
Once the ACPI for serdev will be supported, this plat driver should be
removed.
The serdev driver does no support this yet because I used the RPi3
as dev platform. But this is something we want to have as well.
Making ACPI serdev aware and turning BTH0 into serdev nodes is really the next step. That would allow us to simplify the drivers and remove duplicate code. Do you still have access to ACPI based tablets with Broadcom chips? It would be great if you can take a stab at this.
I have access to an Asus T100TA with Broadcom chipset and I recently
started to work on the ACPI part of SerDev.
I hope to send patches for it soon.
Regards,
Frédéric Danis
