Hello Magnus and Geert, list, this patch series enable the creation of a spidev device though which interface to a MAXREFDES4# MAX11100-ADC evaluation kit connected to Genmai CON2 expansion header. The series is not intended for inclusion but will probably serve as base for future integration of MAX11100 ADC driver. The series is based on branch "genmai-gpio-and-pfc" of Geert's tree at git://git.kernel.org/pub/scm/linux/kernel/git/geert/renesas-drivers.git and target Linux v3.18 The series fix a compilation error for RZ gpio driver and register a gpio based SPI master on CON2 pins. The test bed is setup as: P11_11 (CN2 pin 5) connected as CS P11_10 (CN2 pin 6) connected as MISO P11_9 (CN2 pin 7) connected as SCLK P11_8 (CN2 pin 8) connected as AIN The ADC input is connected to gpio port 11 pin 8 (gpio863) and ADC functionalities have been tested reading the results of successive analog-to-digital conversions and verifying they match the gpio863 output value.
