This series adds new bindings and a device-tree file for the Smartlabs
SML-5442TW set-top box. The original attempt [1] was 15-months ago but
nothing has really changed apart from a change to yaml bindings.
The QCA9377 BT device does not have bindings and early experiments to add
them are partially successful but need further work. I have dropped the
gpio-hog from the device-tree and will submit changes to add BT once the
supporting bits exist elsewhere in the kernel.
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;

The SmartLabs SML-5442TW is broadly similar to the 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
- GPIOX_17 is forced high to enable the QCA9377 module

Can you can create a P231 .dtsi that can be shared between the two?
I'd really like to keep all of these designs that are based on Amlogic
ref designs using shared .dtsi whereever possible.
