Hallo. These Oops and kernel panic were observed on a Zaurus (spitz) machine (ARMv5, PXA270).Looks similar to "Re: [PATCH v2] Input: Make ADS7846 independent on regulator"I don't see any trace in that thread. But yes, I was testing your patch from this thread. Without it, ADS7846 does not work on spitz (ADS7846 does not have any dedicated regulator there). I want to add .needs_regulator bool to ads7846.c and send the patch again to the list.
Please, don't... I thought we've finished discussing the regulator issue... Instead of patching the driver and the platform data and the board file, you should do _either_ of the following: 1) add regulator definition for ads7846 into the board file 2) enable the CONFIG_REGULATOR_DUMMY in your kernel configuration 3) use regulator_use_dummy_regulator() call in the board file. Using either of the above, you will not need the patch for ads7846, only for the board file. -- Regards, Igor.
