[PATCH net v2 0/2] net: stmmac: dwmac-spacemit: Fix wrong macro definition

[Inochi Amaoto]

Fix Wrong macro definition of the Spacemit K3.

Changed from v1:
- https://lore.kernel.org/netdev/20260618064143.1102179-1-inochiama@gmail.com
1. Separate the patch into two patches
2. Use the right macro name for the LPI interrupt.

Inochi Amaoto (2):
  net: stmmac: dwmac-spacemit: Fix wrong phy interface definition
  net: stmmac: dwmac-spacemit: Fix wrong irq definition

[PATCH net v2 1/2] net: stmmac: dwmac-spacemit: Fix wrong phy interface definition

[Inochi Amaoto]

The current MII interface register definition from the vendor is wrong,
use the right number for the macro. Also, correct the interface mask
in spacemit_set_phy_intf_sel() so it can update the register with the
right number

[PATCH net v2 2/2] net: stmmac: dwmac-spacemit: Fix wrong irq definition

[Inochi Amaoto]

The current irq definition of the wake irq and the lpi irq
is wrong, replace them with the right number and name.

This isn't strictly-speaking necessary as this is 0 and val is already 0, maybe
compilers can figure it out and this leaves us with more self-documenting code ?

So I'm ok with that personally,
