- Subject: [PATCH] ARM: dts: sun7i: add bluetooth module to CubieTruck DTS
- The CubieTruck has an AMPAK AP6210 WiFi+Bluetooth module. The
- Bluetooth part is a BCM20710 IC connected to UART2 in the A20
- SoC. The IC also takes a 32.768 KHz low power clock input, a power
- enable signal and a wake signal via GPIO.
- The Bluetooth module supports out-of-band interrupt signaling via
- GPIO, but this is not supported in this patch.
