![]() 0 is used in all pinfunction definitions when a config register is not available, for example imx25-pinfunc.h. If a configuration value is used for such a pinfunction the driver will always write it to the configuration register if it is not -1. For a 0 configuration register the configuration value is written to offset 0x0. This can lead to a crashing/hanging system without any warning message. This patch checks for 0 config register and sets the internal value to -1. If the configuration value is not NO_PADCTL this leads to an error message that applying the configuration failed.
