    Subject[PATCH 5.16 0637/1039] arm64: dts: rockchip: Fix Bluetooth on ROCK Pi 4 boards
    Date
    From: Jagan Teki <jagan@amarulasolutions.com>

    [ 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.
