This is a split-off from the earlier patch set which adds generic pin configuration for the pin controllers that want it. Since we may have a system with mixed generic and custom pin controllers, we pass a boolean in the pin controller ops vtable to indicate if it is generic. ChangeLog v1->v5: - Follow parent patch versioning number system. - Document the semantic meaning of return values from pin config get functions, so we can iterate over pins and check their properties from debugfs as part of the generic config code. - Use proper cast functions in the generic debugfs pin config file. - Expand generic config to optionally cover groups too. ChangeLog v5->v6: - Update to match underlying changes. ChangeLog v6->v7: - Drop DRIVE_OFF parameter, use bias high impedance for this - Delete argument for drive modes push-pull, od and os. These are now just state transitions. - Delete slew rate rising/falling due to discussions on on proper semantics - Drop config wakeup, struct irq_chip does this for now, add back if need be. - Set PIN_CONFIG_END to 0x7fff making room for custom config parameters from 0x8000 and up. - Prefix accessor functions with pinconf_

Say yes here to support GPIO interface on ST-Ericsson U300.
|
|
The names of the two IP block variants supported are
|
|
COH 901 335 and COH 901 571/3. They contain 3, 5 or 7
|
|
ports of 8 GPIO pins each.
