[PATCH 2/3] arm64: tegra: wire up Bluetooth on Jetson TX1 module

From: Tomasz Maciej Nowak
Date: Wed Aug 21 2024 - 15:06:43 EST


From: Tomasz Maciej Nowak <tmn505@xxxxxxxxx>

P2180 modules have Bluetooth in form of BCM4354 chip, and kernel driver
supports this one, so enable it for all users. The necessary firmware
can be obtained from Jetson Linux Archive. bcm4354.hcd file is located
in "Driver Package (BSP)" in
nv_tegra/l4t_deb_packages/nvidia-l4t-firmware_<version>_arm64.deb
archive.
