This converts the bit-banged GPIO SPI driver to looking up and using GPIO descriptors to get a handle on GPIO lines for SCK, MOSI, MISO and all CS lines. All existing board files are converted in one go to keep it all consistent. With these conversions I rarely find any interrim steps...
The simple power sequence provider sets a value for multiple GPIOs in one go so it is better to use the API already provided by the GPIO descriptor API instead of open coding the same logic. http://vger.kernel.org/majordomo-info.html...
