That's why I'm saying provide an option to turn this behaviour on - I agree that it's useful to be able to show the feature, I just think it's going to catch users out if they're not warned that it's happening somehow. > >> (our priority is accuracy of each IP's functioning rather than having > >> all parts of > >> SMDK playing nice with each other on such h/w design issues) > > That'd be the problem, kind of - it does mean people can get burned when > > they pick up the BSP code and use it as a reference for their systems. > I expect people to replace/modify/inspect board specific code before they > run the BSP on their systems.

To be fair the users doing this the individual drivers do look OK by themselves - there's only a problem when it comes to system integration and that's not going to be obvious unless someone has reviewed the drivers while understanding the clock tree for the chip as a whole. -- To unsubscribe from this list: send the line "unsubscribe linux-samsung-soc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
