The ultimate goal is just to prevent the compile error that currently occurs when I2C isn't selected on LPC32XX but UDC is. It's an invalid config combination, not easy to prevent by current Kconfig mechanism. >> @@ -412,6 +411,15 @@ config USB_CNS3XXX_OHCI >> Enable support for the CNS3XXX SOC's on-chip OHCI controller. >> It is needed for low-speed USB 1.0 device support. >> >> +config USB_OHCI_LPC32XX_PNX4008 >> + bool "LPC32XX or PNX4008 OHCI Module" >> + depends on USB_OHCI_HCD >> + depends on USB_ISP1301 >> + ---help--- >> + Enable support for the LPC32XX or PNX4008 SOC's on-chip >> + OHCI controller. >> + It is needed for low-speed USB 1.0 device support. > > Instead you introduce a new symbol to control whether or not ohci-nxp.c > gets compiled.

This issue could be resolved in a different way: Have you followed the discussion at linux-arm-kernel@xxxxxxxxxxxxxxxxxxx on 2012-08-20, Subject "i2c: pnx: Fix bit definitions"? If nothing unexpected turns out, PNX4008 should probably be removed altogether. (Practically abandoned arch for 6 years.) Easily possible for v3.7. Then, the resulting solution is much simpler and Sebastian's patch obsolete.
