Subject[PATCH 1/3] mfd: Add WM1811 support
Date
The WM1811 is mostly register compatible with the WM8994 and WM8958,
providing a high performance audio hub CODEC in a small form factor
suitable for ultra compact system designs.

Due to the ASoC cross dependencies it seems like it'll be easier to
merge this via ASoC - Samuel, does this make sense to you?
