Hi guys, I'm thinking probably in a crazy idea, I hope someone can help me or kill definitely this idea from my mind. I'll explain a little more, the real problem is I don't know how to add support for an expansion board for IGEP v2 board. I see most of boards adds the support inside the board-xxxxx.c file, for example if the expansion board has a Touchscreen interface using ADS7846/TSC2046 they register ads7846 platform data in board-xxxx.c file. This is ok beacause the ads7846 can be detected and if expansion board is not present the detection fails, but maybe other devices in expansion board can't be detected (for example an I/O expansion). So which is the best form to do this ? I'm thinking in create a kernel module for the expansion board that add all the new features, the expansion board should come with a I2C E2PROM for board ID storage, so the idea is create an i2c driver that reads the E2PROM and if found the Board ID inits all the expansion board devices.
don't know if you are aware of that: http://elinux.org/BeagleBoardPinMux#Expansion_boards also beagle.c board file has support for some expansion boards already, maybe there is some code to be shared. -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
