Hi, I'm writing a Linux audio driver for an Intel platform which requires an ACPI firmware node in order to enumerate the device. Other Intel drivers [0] use the i2c-ACPIHID:00 naming convention so I have followed this by setting the CID in my ACPI DSDT table to be "TDA7802". However, I am led to believe this is incorrect [1], and I should assign an official HID.
Do ST have an official ACPI HID for the TDA7802 amplifier? If so, what is it?
Many thanks,
Thomas
