About testing A64 DE2 patches

Hi, kernel people,

I am testing A64 DE2 patches from the list below, series v4, with my 
NanoPi A64 and 4.15

https://patchwork.kernel.org/project/linux-arm-kernel/list/?submitter=173461&page=1

and I'm getting the following issue regarding SRAM:

sunxi-de2-clks 1000000.clock: Error couldn't map SRAM to device

Here is my full dmesg https://pastebin.com/SQvDfJF0

Thanks
