[PATCH 0/3] arm64: dts: amlogic: t7: Add UART support and enable Bluetooth on VIM4

[Ronald Claveau <linux-kernel-dev@aliel.fr>]

This series adds all UART controllers for the Amlogic T7 SoC and enables
the Bluetooth controller on the Khadas VIM4 board.

The T7 SoC ships with six UART controllers (A through F), but only
uart_a was previously described in the device tree.

  - Patch 1 adds the pinctrl group for UART C, which is needed to route
    its four signals (TX, RX, CTS, RTS) through the correct pads.

  - Patch 2 completes the uart_a node (peripheral clock) and
    repositions it to respect the ascending reg address order required
    by the DT specification. It then adds nodes for UART B through F,
    each with their respective peripheral clock.

  - Patch 3 enables UART C on the Khadas VIM4 board and attaches the
    on-board BCM43438 Bluetooth controller to it, with hardware flow
    control, wakeup GPIOs, LPO clock and power supplies.
