drivers/gpio/pca953x.c doesn't register itself with the OF GPIO infrastructure (plus the driver has an absolutely bogus linux,gpio-base stuff, heh). As an example of how to do the OF GPIO properly, see arch/powerpc/platforms/83xx/mcu_mpc8349emitx.c:mcu_gpiochip_add(). Though, soon there will be an easier way to register I2C/SPI chips with the OF GPIO infrastructure.
