We need to add CONFIG to load the serdev Bluetooth driver from the DTS hints. Bluetooth must be configured as built into the kernel, otherwise some components will be loaded in the wrong order. WLAN must be configured as a kernel module, otherwise the driver will not be loaded properly by the SDIO subsystem. If it is started too early, there is no root file system (if initrd is not present) with the required brcm/BCM4330B1.hcd firmware. The pcf8563 driver should not be enabled because it can interrupt the 32 kHz clock after the modules are already powered on, depending on the random driver probe sequence. Signed-off-by: H.
