Is the ACPI probe smart enough to deal with two different drivers registering for the *same* HID? I haven't seen any precedent, e.g. the RT6777 uses a different ACPI HID for its I2C and SPI modes.
I2C and SPI buses, when they are looking for a driver with an ID that matches a device declared in ACPI, will iterate over drivers that belong to the bus only (bus_for_each_drv()). It is not possible for an I2C driver to be matched during SPI device enumeration or vice versa.
Thanks, David
