Merge tag 'powerpc-5.11-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux

2020-12-17T21:34:25+00:00

Pull powerpc updates from Michael Ellerman:

 - Switch to the generic C VDSO, as well as some cleanups of our VDSO
   setup/handling code.

 - Support for KUAP (Kernel User Access Prevention) on systems using the
   hashed page table MMU, using memory protection keys.

 - Better handling of PowerVM SMT8 systems where all threads of a core
   do not share an L2, allowing the scheduler to make better scheduling
   decisions.

 - Further improvements to our machine check handling.

 - Show registers when unwinding interrupt frames during stack traces.

 - Improvements to our pseries (PowerVM) partition migration code.

 - Several series from Christophe refactoring and cleaning up various
   parts of the 32-bit code.

 - Other smaller features, fixes & cleanups.

Pull driver core updates from Greg KH:
 "Here is the big driver core updates for 5.11-rc1

  This time there was a lot of different work happening here for some
  reason:

   - redo of the fwnode link logic, speeding it up greatly

   - auxiliary bus added (this was a tag that will be pulled in from
     other trees/maintainers this merge window as well, as driver
     subsystems started to rely on it)

   - platform driver core cleanups on the way to fixing some long-time
     api updates in future releases

   - minor fixes and tweaks.

  All have been in linux-next with no (finally) reported issues. Testing
  there did helped in shaking issues out a lot :)"

usb: host: sl811: Switch to use platform_get_mem_or_io()

2020-12-10T15:31:46+00:00

Switch to use new platform_get_mem_or_io() instead of home grown analogue.
Note, the code has been moved upper in the function to allow farther cleanups,
such as resource sanity check.

usb: oxu210hp-hcd: Fix memory leak in oxu_create

2020-12-09T14:25:21+00:00

usb_create_hcd will alloc memory for hcd, and we should
call usb_put_hcd to free it when adding fails to prevent
memory leak.

usb: ehci-omap: Fix PM disable depth umbalance in ehci_hcd_omap_probe

2020-12-09T13:33:45+00:00

The pm_runtime_enable will decrement the power disable depth. Imbalance
depth will resulted in enabling runtime PM of device fails later.  Thus
a pairing decrement must be needed on the error handling path to keep it
balanced.

xhci: Give USB2 ports time to enter U3 in bus suspend

2020-12-09T13:32:03+00:00

If a USB2 device wakeup is not enabled/supported the link state may
still be in U0 in xhci_bus_suspend(), where it's then manually put
to suspended U3 state.

Just as with selective suspend the device needs time to enter U3
suspend before continuing with further suspend operations
(e.g. system suspend), otherwise we may enter system suspend with link
state in U0.

xhci-pci: Allow host runtime PM as default for Intel Maple Ridge xHCI

2020-12-09T13:32:03+00:00

Intel Maple Ridge is successor of Titan Ridge Thunderbolt controller. As
Titan Ridge this one also includes xHCI host controller. In order to
safe energy we should put it to low power state by default when idle.
For this reason allow host runtime PM for Maple Ridge.

xhci-pci: Allow host runtime PM as default for Intel Alpine Ridge LP

2020-12-09T13:32:03+00:00

The xHCI controller on Alpine Ridge LP keeps the whole Thunderbolt
controller awake if the host controller is not allowed to sleep.
This is the case even if no USB devices are connected to the host.

Add the Intel Alpine Ridge LP product-id to the list of product-ids
for which we allow runtime PM by default.
