Hello Paolo,
I believe one of my teammates is currently working on adding a KVM
selftest for SEV and SEV-ES.
Thanks,
Ashish

Quite similar to the regulator bindings found in "rockchip-pcie-host.txt",
this allows optional regulators to be attached and controlled by the
PCIe RC driver.

v2 -- Use regulator bulk API rather than multiple calls (MarkB).
v1 -- Bindings are added for fixed regulators that may power the EP device.
-- The brcmstb RC driver is modified to control these regulators
during probe, suspend, and resume.
-- 7216 type SOCs have additional error repor
This distinction is required for an imminent commit.

If any downstream device may wake up during S2/S3 suspend, we do not want
to turn off its power when suspending.

Whereas most PCIe HW returns 0x on illegal accesses and the like,
by default Broadcom's STB PCIe controller effects an abort. This simple
handler determines if the PCIe controller was the cause of the abort and if
so, prints out diagnostic info.
Example output:
brcm-pcie 8b2.pcie: E
Control of EP regulators by the RC is needed because of the chicken-and-egg
situation: although the regulator is "owned" by the EP and would be best
handled on its driver, the EP cannot be discovered and probed unless its
regulator is already turned on.

Masami,
Can you review this patch, and also, should this go to -rc and stable?

A quick background for Greg and others who haven't seen the Sept-Oct
discussion between me and Johan on the linux-usb ML: I am the hardware
engineer who designed the FT2232D-based DUART28C adapter board, and it
was my desire to have this custom FT2232D adapter supported in mainline
Linux that trigg
