2024-06-21MIPS: dts: loongson: Add ISA nodeJiaxun Yang1-0/+7
ISA node is required by Loongson64 platforms to initialize PIO support. Kernel will hang at boot without ISA node. Cc: [email protected] Signed-off-by: Jiaxun Yang <[email protected]> Signed-off-by: Thomas Bogendoerfer <[email protected]>
2024-06-21MIPS: dts: loongson: Fix GMAC phy nodeJiaxun Yang1-2/+4
phy-mode should be rgmii-id to match hardware configuration. Also there should be a phy-handle to reference phy node.

Device binds to proper PCI ID (LOONGSON, 0x7a03), already listed in DTS, so checking for some other compatible does not make sense. It cannot be bound to unsupported platform.
