i.MX arm32 DT changes for 5.3:
 - New board support: iMX6-based Kontron SMARC-sAMX6i, i.MX7D based
   Meerkat96 board, and NXP LS1021A-TSN board.
 - A series from Andrey Smirnov to update vf610-zii-dev and
   imx7d-zii-rpu2 board, fixing UART2 pin assignment and stdout-path,
   adding QSPI device, and dropping unused pinmux.
 - Update imx6sl and imx6qdl device tree to assign corresponding clocks
   instead of dummy clock.
 - Update i.MX6/7 boards from NXP to assign corresponding power supply
   for LDOs.
 - Update i.MX6/7 device trees to enable SNVS poweroff key support
   according to board design.
 - Update coresight DT binding for i.MX7 according to consolidations
   for CoreSight replicator and funnel.
 - A series from Marek Vasut to update M53Menlo board on various devices
   like UART, USB, ethernet PHY, GPIOs etc.
 - Enable USBOTG support for imx7ulp and evk board.
 - A series from Peter Robinson to update imx6sx-udoo board, switching
   to SPDX License Identifier, enabling I2C devices and bluetooth
   support.
 - Add video capture support for i.MX53 and imx53-smd board.
 - Add PXP device for i.MX6UL.
 - Other random small updates on various boards.
