Added delay requirement between VDD_IN and POWER_EN (400ms min)

“NVIDIA Jetson TX2 NX Product Design Guide” is changed in V1.2
Added delay requirement between VDD_IN and POWER_EN (400ms min)

I already made my custom board (not meet new Spec)

what is purpose of this change?

It’s for 32khz clock stabilization. Please try to fit that.

not so hard but need more cost

I don’t use 32KHz. Can I ignore 400ms delay?
My custom board is designed with 120ms ~ 280ms delay

Please follow latest guide to fix the timing.
