Hey Xo, For some reason I didn't get this mail from you. Luckily I saw it in patchwork.

We already set these aliases in aspeed-g5.dtsi, so you shouldn't need this patch.

Make numbering for I2C buses consistent across boots by assigning aliases to all the bus blocks in the peripheral, including the ones that are currently disabled. This way, Linux reserves bus numbers for buses that are disabled, instead of filling in those number gaps with logical I2C buses from muxes.
