[PATCH v2 0/2] Enable uart and bluetooth for Xperia devices

[Petr Hodina via B4 Relay]

This fixes the uart instances defined in the dts so the serial
console will now work if uart is attached to Rx pin on the uSD pinout.
Also now enables bluetooth.

[PATCH v2 1/2] arm64: dts: qcom: sdm845-sony-xperia-tama: Correct uart instances

[Petr Hodina via B4 Relay]

From: Petr Hodina <petr.hodina@protonmail.com>

Change the uart instances:
- uart6 is for bluetooth
- uart9 is for serial console (available on the uSD pinout)

Most OSes assume serial0 is for console UART. Bluetooth interface uses
UART interface. uart6 is standard debug console and uart9 bluetooth on
SDM845 devices.
