[PATCH 2/3] arm64: dts: freescale: add initial device tree for MBa93xxLA SBC board

From: Alexander Stein
Date: Fri Jun 09 2023 - 09:29:40 EST

This adds support for TQMa93xx module and MBa93xxLA SBC board.
TQMa93xx is a SOM using i.MX93 SOC. The SOM features PMIC, RAM, e-MMC and
some optional peripherals like SPI-NOR, RTC, EEPROM, gyroscope and
secure element.
TQMa93xxLA is a solder on type SOM and can be used directly on MBa93XXLA.
TQMa93xxCA is a feature compatible, socketable type SOM.
