Can you show some example how we could use this new code for example with an existing I2C/SPI slave driver? Let's say the device uses few GPIOs, one for interrupt and other for triggering firmware download. In addition to that it needs a special parameters that can be extracted running the "_DSM" method of the device. Normally the driver would get this stuff from the platform data or from Device Tree but how it is done with these patches?
