I've downloaded the kernel from https://github.com/Digilent/linux-digilent.git and try to recompile the kernel by,
> make xilinx_zynq_defconfig
However, at the final stage, it reports a lot of errors in clock_divider.o and most of the errors are related to adv7511.
What's wrong with it? How should I recompile the kernel correctly? And how should I patch the kernel?
Could you show me step by step?
