Generator) module generates clock and reset signals used
by other module blocks on SoC.

Hi, is there any mainline kernel or uboot for hisilicon hi3520dv200 or
hi3520dv300? just want some base support to boot , anything close to
mainline is ok :)

Sorry. I wasn't engaged in hi3520d project. I have no detailed information about it.
As far as I know, most of HiSilicon products include a written offer document. You
can check it out and apply for the source code following the instructions.

And you should have signed it off? Care to resend or state that
this is incorrectly attributed to you instead of Pan Wen?

Pan Wen is the main author of this patch. I just made some small modification
with agreement from him. Do I need to resend this patch if it's better to add my
signed-off?

Thanks,

Sure I'll apply the resent one. But you should also make sure to
retain Pan Wen's authorship. I'll go do that when applying it.
