So, please run this before make clean. So, for building it, you will do: $ ./scripts/config -e CONFIG_VIDEO_ATOMISP_ISP2401 && make -j modules_prepare $ make -j4 clean && make -j4 $ sudo make modules_install INSTALL_MOD_STRIP=1 && sudo make install This won't change the regulator detection, but it should hopefully use the ISP2401-specific code, with seems to be needed for your device. Ah, when replying, could you please use an emailer that won't be breaking long lines? Your emailer is currently breaking lines longer than 80 columns, with is quite annoying when checking log results ;-) Thanks, Mauro
