On the other hand, arch/arm is getting soo big that we need to do something about this - and one solution is to avoid unnecessary definitions that we're not using. Another good idea is to put definitions along side the drivers which they're relevant to - maybe in a local driver-name.h file which driver-name.c includes, or maybe even within driver-name.c if they're not excessive. This has the advantage of distributing the "bloat" to where its actually used, and means that the driver isn't dependent so much on arch/arm or even the SoC itself. Take a look at arch/arm/mach-vexpress/include/mach/ct-ca9x4.h and arch/arm/mach-vexpress/include/mach/motherboard.h - these are the only two files which contain platform definitions which are actually used for Versatile Express. Compare that with arch/arm/mach-realview/include/mach/platform.h which contains lots more... -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
