Differing from the EVM, we add the virtual ethernet controller device below &icssg1 instead of the top level. Besides being slighly more accurate, this has the advantage that the node is implicitly disabled when &icssg1 has status = "disabled" (which the TQMa64xxL bootloader adds as a fixup when running on an AM64x variant without ICSSG support), thus avoiding leaving the ethernet device in EPROBE_DEFER limbo forever. Signed-off-by: Matthias Schiffer --- k3-am642-evm.dts uses "ti-pruss/am64x-sr2-*" filenames instead of "ti-pruss/am65x-sr2-*", however it is not clear to me where these would come from - I'm not aware of any firmwares named like that. So far, these firmwares are not in mainline linux-firmware; TI's reference BSPs include firmware from ti-linux-firmware [1], and the same "am65x-sr2" firmwares are used on AM65x and AM64x SoCs.
