I'm trying to read data from a SGTL5000 audio CODEC, which has 16-bit addresses and 16-bit wide data registers.

Unless I'm missing something, it looks impossible to read these registers using i2cget, because it only supports 8-bit addresses. Is there any other similar tool, or should I patch i2cget to support 16-bit addresses?

Regards,
Craig McQueen

If you're running Linux why are you trying to use i2cget to interact
with the register map?  There's a driver for the device using regmap...
