[PATCH 0/3] arm64: hi6220-hikey: Fix Bluetooth support

[Marcel Holtmann]

Hi Ulf,

> The commit ea452678734e ("arm64: dts: hikey: Fix WiFi support") indeed managed
> to fix the WiFi support for the Hikey board. However, it also caused the
> Bluetooth to break.
> 
> The reason to the problem is because part of the fixes for WiFi, involved
> explicitly to start manage the external clock for the TI WiLink chip, as it's
> needed to properly power on/off WiFi. Then, because the Bluetooth driver,
> hci_ll, don't manage the clock, it fails to initialize Bluetooth.
> 
> This small series add support and DT bindings for the external clock, now
> properly managed by the hci_ll driver during power on/off. On top of that, the
> external clock is added to the Bluetooth DT node in the Hikey DTS file.
> 
> The regression has been reported by John Stultz, running a Hikey board with
> UEFI based boot. I have confirmed that there is no regressions with u-boot as
> we still don't have bluetooth working on that set up. I intend to fix that as
> well, although in second step and not being part of a fixup series.
> 
> John, can you please confirm/test this on your Hikey board using UEFI!?
> 
> Perhaps this can go in via the bluetooth git, when respective patches has got
> an ack. Or whatever you think is best.
