Bluetooth: hci_uart: Add support for Amlogic HCI UART

2024-09-10T16:44:10+00:00

Add a new HCI protocol HCI_UART_AML for the Amlogic Bluetooth controller. It works on the standard H4 protocol via a 4-wire UART interface, with baud rates up to 4 Mbps. The controller supports two types of commands: the TCI commands and the vendor command. The former is for initial setup including setting baud rates, downloading fw, starting chip and etc, while the latter is for dumping firmware versions and setting public address after firmware updates and normal startup. It was verified on board of T602 (S905X4 + W265S2). dmesg: .. [ 5.313450] Bluetooth: HCI UART protocol AML registered [ 6.506052] Bluetooth: hci0: fw_version: date = 42.28, number = 0xb2fd ...

Bluetooth: NXP: Add protocol support for NXP Bluetooth chipsets

2023-04-24T04:51:55+00:00

This adds a driver based on serdev driver for the NXP BT serial protocol based on running H:4, which can enable the built-in Bluetooth device inside an NXP BT chip. This driver has Power Save feature that will put the chip into sleep state whenever there is no activity for 2000ms, and will be woken up when any activity is to be initiated over UART. This driver enables the power save feature by default by sending the vendor specific commands to the chip during setup. During setup, the driver checks if a FW is already running on the chip by waiting for the bootloader signature, and downloads device specific FW file into the chip over UART if bootloader signature is received..
