The context is wrong here, could you regen the series on top of
net-next (and resend with [PATCH net-next v9] in the subject while
at it)?

Hi Jakub,

Thanks,  I will resent with [PATCH net-next v9].
My series of patches will depend on Hal's minimal system[1] and william's syscon patch[2], and this context comes from their patch.

[1]: https://patchwork.kernel.org/project/linux-riscv/cover/20230320103750.60295-1-hal.feng@starfivetech.com
[2]: https://patchwork.kernel.org/project/linux-riscv/cover/20230315055813.94740-1-william.qiu@starfivetech.com

Do I need to remove their context?


Best regards,
Samin

If the conflict is just on MAINTAINERS it should be safe to ignore.
Resend your patches on top of net-next as if their patches didn't
exist. Stephen/Linus will have not trouble resolving the conflict.

I see, I'll send net-next as you suggest.

required: goes after properties:

Just like in example-schema.
