Some platforms (e.g. OpenFirmware) want to know when a particular chip
added or removed, so that the platforms could add their specifics for
non-platform devices, like I2C or SPI GPIO chips.
This patch implements the notifier for chip addition and removal events.

I'm no
Some platforms (e.g. OpenFirmware) want to know when a particular chip
added or removed, so that the platforms could add their specifics for
non-platform devices, like I2C or SPI GPIO chips.
This patch implements the notifier for chip addition and removal events.
