-Subject: [PATCH] BCM270X_DT: Add pi3-miniuart-bt DT overlay
-
-Switch Pi3 Bluetooth function to use the mini-UART (ttyS0) and restore
-UART0/ttyAMA0 over GPIOs 14 & 15. Note that this may reduce the maximum
-usable baudrate.
-
-It is also necessary to edit /lib/systemd/system/hciuart.server and
-replace ttyAMA0 with ttyS0.
-
-If cmdline.txt uses the alias serial0 to refer to the user-accessable port
-then the firmware will replace with the appropriate port whether or not
-this overlay is used.
