The default sizes are 1 cell for address and size, so this will give
you warnings. You either need to adjust the entries here or add a
parent node setting the sizes to 2 cells.
Thanks Rob.
tegra210.dtsi already has address and size set to 2 cells in parent node
of sata.
Do you mean to add parent node and address and size cells set to 2 in
this yaml example as well?
+ interrupts = <GIC_SPI 23 IRQ_TYPE_LEVEL_HIGH>;
The error is because you need the include files for these defines.
Will add header file for interrupts in yaml example.
