From: Jagan Teki <jagan@xxxxxxxxxxxxxxxxxxxx> [ Upstream commit f471b1b2db0819917c54099ab68349ad6a7e9e19 ] This patch fixes the Bluetooth on ROCK Pi 4 boards. ROCK Pi 4 boards has BCM4345C5 and now it is supported on Mainline Linux, brcm,bcm43438-bt still working but observed the BT Audio issues with latest test. So, use the BCM4345C5 compatible and its associated properties like clock-names as lpo and max-speed. Attach vbat and vddio supply rails as well.
