Make MediaTek's controller driver capable of controlling power
supplies and reset pin of a downstream component in power-on and
power-off process.
Some downstream components (e.g., a WIFI chip) may need an extra
reset other than PERST# and their power supplies, depending on
the requirements of platform, may need to controlled by their
parent's driver. To meet the requirements described above, I add this
feature to MediaTek's PCIe controller driver as an optional feature.
NAK, strong NAK. This should be done in a generic way because nothing
here is specific to Mediatek.
You just implement power sequencing of devices through quirks specific
to one controller.
Work with others to provide common solution.
