Merge tag 'at91-dt-6.20' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into soc/dt
Microchip AT91 device tree updates for v6.20
This update includes:
- update the SAMA7D65 flexcom nodes to add the missing i2c, spi, and usart
child nodes; the flexcom child nodes were also updated with DMA
properties
- add basic support for the PCB8385 board, based on LAN966X SoC
- drop usb_a9g20-dab-mmx.dtsi as it is not used anywhere in the tree
