Btw, as for pins marked X... If the gpio controller has some register that specify which pins are not available to use as GPIOs, then just read that register, check its value and return -ENODEV from the .request() gpiolib callback. This is easily doable for QE/CPM gpio controllers (they have option registers), but nobody cares to check them. -- Anton Vorontsov email: [EMAIL PROTECTED] irc://irc.freenode.net/bd2 _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@ozlabs.org https://ozlabs.org/mailman/listinfo/linuxppc-dev
