- Subject: [PATCH 17/25] net: mediatek: remap iobase address
- The iobase address from dts node is actually physical address. It's
- identical to the virtual address in ARM platform. This is ok because this
- driver was used only by ARM platforms (mt7622/mt7623 ...).
- But now this driver will be used by mt7621 which is a MIPS SoC. For MIPS
- platform the physical address space is mapped to KSEG0 and KSEG1 and this
- makes the virtual address apparently not idential to its physical address.
- To solve this issue, this patch replaces dev_read_addr with dev_remap_addr
- to get the remapped iobase address.
