Can you send me a series that just adds the hardware support for now, so
we can dash this PM issue out separately?
Hi, we need to provide this information to our device.
We face the HW signal issue on various motherboards.
We experiment on many motherboards, and we observe that the restart
signal is different on different motherboard. If device misses the
signal, PCI loss or volume disappearance might happen.
To make power management easier, driver provide the shutdown or reboot
information to the device.
Sorry, I'm not understand what is meaning of "series".
Could you specify what you what me to send you?
Thank you

Hi, after our internal discussion, we can use shutdown flow for reboot
temporarily. Some signal issue will happen (depend on MB), and it can be
fixed by plug in and plug out manually. We will add reboot feature after
PM can pass reboot information to ->shutdown.
