Unfortunately this approach leads to inability to make the bindings modular. Note that distributions compile kernels with allmodconfig*, so the kernel builds with all modules, but _all_ these bindings will be kernel's built-ins. Given that these bindings are needed for every not-so-trivial I2C (or SPI) driver, the approach doesn't seem to scale good enough. You can find more discussion on this matter in this huge thread: http://lkml.org/lkml/2008/10/16/248 And the solution that everybody seem to agree with (SPI driver example): http://lkml.org/lkml/2008/10/30/393 * Well, this is not quite true, but they're very close to allmodconfig. -- Anton Vorontsov email: cbouatmai...@gmail.com irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
