[PATCH v8 0/3] arm64: dts: meson: add dts/bindings for SmartLabs SML-5442TW

[Christian Hewitt]

This series adds new bindings and a device-tree file for the Smartlabs
SML-5442TW set-top box which is based on the P231 reference design.

As requested, I have reworked the device-tree on the p23x-q20x dtsi. I
have also re-added the BT device with new bindings that have now  been
merged in bluetooth-next for inclusion in Linux 5.8. See [1].

v8 - reworked on p23x-q20x dtsi
   - add BT module

v7 - update gpio-led nodes
   - remove gpio-hog for BT enable
   - add bindings acks from Rob

v6 - removed audio nodes again

v5 - typo in card name

v4 - typos/corrections from Andreas
   - convert to yaml bindings
   - add sound node back
   - confirmed gpio-hog is necessary

v3 - change to Smartlabs LLC
   - removed sound node

v2 - removed audio nodes
   - changes soundcard name to "meson-gx-audio"
   - added missing uart-has-rtscts;

[PATCH v8 3/3] arm64: dts: meson: add support for the Smartlabs SML-5442TW

[Christian Hewitt]

The Smartlabs SML-5442TW is based on the Amlogic P231 reference design
but with the following differences:

- The Yellow and Blue LEDs are available but disabled
- The Red and Green LEDs are used to signal off/on status
- uart_AO can be accessed after opening the case; soldered pins exist
- QCA9377 instead of the usual Ampak/Broadcom module
