Hi Jonas, I applied your four patches for the Odroid M1S to the mainline kernel [1], compiled it using the kernel configuration from the Hardkernel Ubuntu Server Image [2], and then attempted to boot into the official Generic AArch64 image on mmcblk0 using a dtb file and an Arch Linux initrd by manually copying the kernel and dtb file to the boot partition and booting manually with the vendor's U-Boot [3]. The booting process was successful! However, the network interface is not working. Here is the relevant dmesg output: ---- [ 6.694455] rk_gmac-dwmac fe010000.ethernet: IRQ eth_lpi not found [ 6.695030] rk_gmac-dwmac fe010000.ethernet: IRQ sfty not found [ 6.702424] rk_gmac-dwmac fe010000.ethernet: clock input or output?
