[PATCH v1 2/2] Bluetooth: btnxpuart: Update firmware names

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This updates the firmware names of 3 chipsets: w8987, w8997, w9098.
These changes are been done to standardize chip specific firmware
file names.
To allow user to use older firmware file names, a new device tree
property has been introduced called firmware-name, which will override
the hardcoded firmware names in the driver.
