[RESEND PATCH 0/2] Add bluetooth support for Orange Pi 3

[RESEND PATCH 0/2] Add bluetooth support for Orange Pi 3

[megous]

From: Ondrej Jirman <megous@megous.com>

(Re-send for Maxime, with already applied patches dropped. Nothing new.)

This series implements bluetooth support for Xunlong Orange Pi 3 board.

The board uses AP6256 WiFi/BT 5.0 chip.

Summary of changes:

- add more delay to let initialize the chip
- let the kernel detect firmware file path
- add new compatible and update dt-bindings
- update Orange Pi 3 / H6 DTS

Please take a look.

thank you and regards,
  Ondrej Jirman

[RESEND PATCH 1/2] arm64: dts: allwinner: h6: Add pin configs for uart1

From: Ondrej Jirman <megous@megous.com>

Orange Pi 3 uses UART1 for bluetooth. Add pinconfigs so that we can use
them.

[RESEND PATCH 2/2] arm64: dts: allwinner: orange-pi-3: Enable UART1 / Bluetooth

[megous]

From: Ondrej Jirman <megous@megous.com>

The board contains AP6256 WiFi/BT module that has its bluetooth part
connected to SoC's UART1 port. Enable this port, and add node for the
bluetooth device.

Bluetooth part is named bcm4345c5.

You'll need a BCM4345C5.hcd firmware file that can be found in the
Xulongs's repository for H6:

https://github.com/orangepi-xunlong/OrangePiH6_external/tree/master/ap6256

The driver expects the firmware at the following path relative to the
firmware directory:

  brcm/BCM4345C5.hcd
