[PATCH 0/2] arm64: dts: amlogic: add libretech cottonwood support

This patchset adds support for the Libretech cottonwood board family.
The 2 boards are based on the same PCB, with an RPi B form factor.

The "Alta" board uses an a311d while the "Solitude" variant uses an s905d3.

This patchset depends on the usb support for the gl3510 [0]
Without it, there will be dt check warnings and usb may not come up properly.

Early u-boot support may be found here [1]. It will be submitted after
DT is accepted in Linux. As usual with Amlogic, u-boot must be packaged
with closed source binaries ([2] for the a311d, [3] for the s905d3)

Prebuilt bootloaders are available from libretech [4].

The devices are shipped with libretech's u-boot pre-flashed in SPI NOR.
If necessary, the boot source may be changed to MMC using the onboard
switch.

Happy hacking ...
