-Subject: [PATCH] ARM: dts: Add Bluetooth nodes for Raspberry Pi
-
-Add device tree nodes for Bluetooth on supported Raspberry Pi boards.
-It's disabled by default and can be enabled by `krnbt=on` dtparam. It's
-an alternative way of configuring Bluetooth, as compared to hciattach or
-btattach. When the dtparam is enabled, the Bluetooth driver is probed
-automatically and doesn't require any additional bring-up scripts.
-
-Note that Raspberry Pi 3 B rev 1.2 doesn't have the required hardware
-flow control pins of UART0 connected to the Bluetooth module, so the
-user should decrease the baudrate by passing `krnbt_baudrate=921600`
-dtparam to make it more stable. It resembles the behavior of the btuart
-script from Raspbian.
-
-The miniuart-bt overlay was modified to support Bluetooth probing with
-device tree, too. It's disabled by default and can be enabled by
-`krnbt=on` parameter of the miniuart-bt overlay.
