[PATCH v5 0/5] arm64: dts: qcom: support SDM845 HDK

[Dmitry Baryshkov]

Lantronix HDK845 aka Qualcomm SDM845-HDK is a hardware development kit
for the Qualcomm SDM845 / SDA845 platform. It uses the modem-less
version of the chip (SDA845) and provides a rich set of the peripherals
and connectors. The DSI panel is an optional addon, so it is being split
to a separate overlay. To (hopefully) ease merging, the overlay is split
to a separate patch as it depends on the panel. The base DT doesn't have
external dependencies.
