XHCI specification 1.1 does not require xHCI-compliant controllers
to always enable hardware USB2 LPM. However, the current xHCI
driver always enable it when seeing HLC=1.
This patch supports an option for users to control disabling
USB2 Hardware LPM via DT/ACPI attribute.
This option is needed in

pci_target_state() calls device_may_wakeup() which checks whether
or not the device may wake up the system from sleep states, but
pci_target_state() is used for runtime PM too.
Since runtime PM is expected to always enable remote wakeup if
This patch uses the previously introduced macro called
request_declared_muxed_region() to synchronize access to
the I/O port pair 0xcd6 / 0xcd7 on SB800.
These I/O ports are also used by i2c-piix4 and sp5100_tco,
so synchronization is necessary. The other drivers will also
be modified to use the
In order to make request_*muxed_region() behave more like
mutex_lock(), a possible failure case needs to be eliminated.
When drivers do not properly share the same I/O region, e.g.
one is using request_region() and the other is using
request_muxed_region(), the kernel didn't warn the user about

i2c: piix4: Add support for multiplexed main adapter in SB800
The regression caused sp5100_tco fail to
Add a new IORESOURCE_ALLOCATED flag that is automatically used
when alloc_resource() is used internally in kernel/resource.c
and free_resource() now takes this flag into account.
The core of __request_region() was factored out into a new function
called __request_declared_region() that needs
Use the new request_declared_muxed_region() macro to
synchronize access to the I/O port pair 0xcd6 / 0xcd7.
At the same time, remove the long lifetime request_region()
call to reserve these I/O ports, so the sp5100_tco watchdog
driver can also load.
This fixes an old regression in Linux 4.4-rc4,
Use the new request_declared_muxed_region() macro to synchronize
accesses to the SB800 I/O port pair (0xcd6 / 0xcd7) with the
PCI quirk for isochronous USB transfers and with the i2c-piix4
driver.
At the same time, remove the long lifetime request_region() call
to reserve these I/O ports,
