It appears that GPIO DW APB driver wasn't touched for a long time. Here is the fix for long standing issue, i.e. missed module alias to make the driver be loaded automatically. On top of above a lot small clean ups here and there. The series based on the v3 by Serge Semin which he sent earlier. Driver has been tested on Intel Galileo Gen2 with AT25 SPI EEPROM using it for a chip select.
