Hi Conor,

Thanks for the review.

I apologize for the missing commit message; I will add a proper 
description in v2.

Regarding the email address, my Nuvoton mail adds a corporate 
confidentiality disclaimer to outgoing
external mail, so I use my personal address for sending kernel patches.

Noted. I will add the `num-cs` and `resets` properties in v2.

Understood, I will remove the flash child node from the example in v2.

Thanks,
Chi-Wen Weng
