Can you include the i2c aliases for hsi2c_12 and hsi2c_8 (added by Tudor
previously)? This will ensure userspace compatibility with the existing Pixel
userspace builds.
Feel free to do so in a follow-up patch, but I'd prefer the aliases get
included in the same kernel release that these devices were added in (v6.9).
Thanks,
Will
