[PATCH v1 1/3] dts: add Nuvoton sgpio feature

[Jim Liu]

Hi Krzysztof Kozlowski

Thanks for your review.
I am modifying this driver now, and i have some questions.

what's mean "Generic node name." ?
Nuvoton NPCM750 SGPIO module is base on serial to parallel IC (HC595)
and parallel to serial IC (HC165).
and dts node name is followed aspeed dts node name.

Could you give more information??

Best regards,
Jim
