[PATCH 2/2] arm64: dts: ls1012a: add DTS for TQMLS1012al module with MBLS1012AL board

Alexander Stein alexander.stein at ew.tq-group.com
Mon Apr 28 23:40:54 PDT 2025 

From: Matthias Schiffer <matthias.schiffer at tq-group.com>

Add initial support for TQMLS1012AL module mounted on MBLS1012AL.
It supports UART1 for console, PCIe, I2C, USB, µSD card (default), SATA
and QSPI.
There is an alternative ordering option which provides an eMMC instead of
an SD card. This uses a different DT instead.
Due missing Packet Forwarding Engine (PFE) driver support, there is no
support for Ethernet so far.
