This makes the patch a bit more complicated than we would like so let's explain why the current approach was used. The different address ranges between the two variants can be represented with 7 different sets of #ifdefs like the following: #if IS_ENABLED(CONFIG_DWMAC_QCOM_VER3) # define MTL_CHAN_BASE_ADDR 0x00008000 # define MTL_CHAN_BASE_OFFSET 0x1000 #else # define MTL_CHAN_BASE_ADDR 0x00000d00 # define MTL_CHAN_BASE_OFFSET 0x40 #endif This won't be acceptable for upstream inclusion since it would be nice to enable both variants simultaneously without recompiling. The next approach that was checked was to have a function pointer embedded inside a structure that does the appropriate conversion based on the variant that's in use. However, some of the function definitions are like the following: void emac3_set_rx_ring_len(void __iomem *ioaddr, u32 len, u32 chan) We can't do a container_of() with an __iomem address. Changing these functions to pass in an extra regular structure had a cascading effect across the different variants, and the change was quickly becoming large. It would also be hard to test and review. So the approach that was decided to go with here is to take the existing dwmac4_XXX callbacks, rename it to do_XXX, and do the following: static void do_XXX(..., int addr_offset) { // Code from existing dwmac4 implementation. } static inline void emac3_XXX(...) { do_XXX(..., EMAC3_ADDR_OFFSET(...)); } static inline void dwmac4_XXX(...) { do_XXX(..., DWMAC4_ADDR_OFFSET(...)); } Prior to the introduction of this patch, dwmac4_dma_init_channel() and dwmac410_dma_init_channel() already had the problem of copy and paste with trivial changes made. While changes are being made here, this patch also fixes a bad comment that was in dwmac4_config_cbs (s/high/low).

While at it refactor it slightly to be more readable, including fixing the typo in the variable name.
