make bcm2835_defconfig

enable both driver via make menuconfig

make savedefconfig

mv defconfig arch/arm/configs/bcm2835_defconfig.2

diff -u arch/arm/configs/bcm2835_defconfig 
arch/arm/configs/bcm2835_defconfig.2 > config.patch

manually add only the relevant changes from config.patch in 
arch/arm/configs/bcm2835_defconfig

generate the patch as usual

goal is to have simple patch which only contains the 2 driver changes 
without any clean-up changes
