You might want to get in touch with Tomas Holmqvist, who contacted us some times ago for a similar problem: http://archives.andrew.net.au/lm-sensors/msg29831.html I think I remember that the LPC47M15x and LPC47M192 are mostly compatible (would need to verify with the datasheets whether this applied to the HWM block as well). If this is the case, it would probably make sense to join your forces and write a single driver for both chips. Thanks, -- Jean Delvare
