4a5705a9c2 bus: sunxi-rsb: Add Allwinner Reduced Serial Bus (RSB) controller bindings
Reduced Serial Bus is a proprietary 2-line push-pull serial bus supporting
multiple slave devices. It was developed by Allwinner, Inc. and used by
Allwinner and X-Powers, Inc. for their line of PMICs and other peripheral
ICs.

Recent Allwinner SoCs, starting with the A23, have an RSB controller. This
is used to talk to the PMIC, and later with the A80 and A83 platform, the
audio codec IC.

8eb5c87a92 i2c: add ACPI support for I2C mux ports
Although I2C mux devices are easily enumerated using ACPI (_HID/_CID or
device property compatible string match), enumerating I2C client devices
connected through an I2C mux needs a little extra work.

This change implements a method for describing an I2C device hierarchy that
includes mux devices by using an ACPI Device() for each mux channel along
with an _ADR to set the channel number for the device.  See
Documentation/acpi/i2c-muxes.txt for a simple example.

To make this work the ismt, i801, and designware pci/platform devs now
share an ACPI companion with their I2C adapter dev similar to how it's done
in OF.  This is done on the assumption that power management functions will
not be called directly on the I2C dev that is sharing the ACPI node.

   PMU_SPARE2 (0x908) in the same way as on Exynos3250: as a indicator
   the secondary CPU was booted on. The bootloader will set this value
   to non-zero, after sucessfull power up of secondary CPU. In the same
   time this booted CPU will stuck (spin) waiting for software reset.
2. Exynos542x entry address for secondary CPU boot up after system

8e3c595214 mailbox/omap: Add ti,mbox-send-noirq quirk to fix AM33xx CPU Idle
The mailbox framework controls the transmission queue and requires
either its controller implementations or clients to run the state
machine for the Tx queue. The OMAP mailbox controller uses a Tx-ready
interrupt as the equivalent of a Tx-done interrupt to run this Tx
queue state-machine.

The WkupM3 processor on AM33xx and AM43xx SoCs is used to offload
certain PM tasks, like doing the necessary operations for Device
PM suspend/resume or for entering lower c-states during cpuidle.

The CPUIdle on AM33xx requires the messages to be sent without
having to trigger the Tx-ready interrupts, as the interrupt
would immediately terminate the CPUIdle operation. Support for
this has been added by introducing a DT quirk, "ti,mbox-send-noirq"
and using it to modify the normal OMAP mailbox controller behavior
on the sub-mailboxes used to communicate with the WkupM3 remote
processor. This also requires the wkup_m3_ipc driver to adjust
its mailbox usage logic to run the Tx state machine.

NOTE:
- AM43xx does not communicate with WkupM3 for CPU Idle, so is
  not affected by this behavior. But, it uses the same IPC driver
  for PM suspend/resume functionality, so requires the quirk as
  well, because of changes to the common wkup_m3_ipc driver.

a4d8e93c31 usb: patches for v4.4 merge window
This pull request is large with a total of 136 non-merge
 commits. Because of its size, we will only describe the big things in
 broad terms.
 
 Many will be happy to know that dwc3 is now almost twice as fast after
 some profiling and speed improvements. Also in dwc3, John Youn from
 Synopsys added support for their new DWC USB3.1 IP Core and the HAPS
 platform which can be used to validate it.
 
 A series of patches from Robert Baldyga cleaned up uses of
 ep->driver_data as a flag for "claimed endpoint" in favor of the new
 ep->claimed flag.
 
 Sudip Mukherjee fixed a ton of really old problems on the amd5536udc
 driver. That should make a few people happy.
 
 Heikki Krogerus worked on converting dwc3 to the unified device property
 interface.
 
 Together with these, there's a ton of non-critical fixes, typos and
 stuff like that.

The current behavior is to try to get optional clocks and print a

We may need a cleaner way to handle per-device clocks but in the

Merge tag 'firmware/psci-1.0' of git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux into next/drivers

This pull request contains patches that enable PSCI 1.0 firmware
features for arm/arm64 platforms:

- Lorenzo Pieralisi adds support for the PSCI_FEATURES call, manages
  various 1.0 specifications updates (power state id and functions return
  values) and provides PSCI v1.0 DT bindings
- Sudeep Holla implements PSCI v1.0 system suspend support to enable PSCI
  based suspend-to-RAM

* tag 'firmware/psci-1.0' of git://git.kernel.org/pub/scm/linux/kernel/git/lpieralisi/linux:
  drivers: firmware: psci: add system suspend support

50760cad9d ASoC: fsl-asoc-card: add AC'97 support
Add AC'97 support to fsl-asoc-card using generic
ASoC AC'97 CODEC.

The SSI controller will silently enable any TX
AC'97 slots that have their bits set in SLOTREQ
received from CODEC and then will redirect some
of playback samples there.

That's why it is important to make sure that
any of CODEC playback slots that can pull samples
are set to slots 3/4 (standard PCM playback slots).
Currently, this applies to S/PDIF slots as they
were seen to pull samples sometimes even with
S/PDIF output being disabled.

53e597b1d1 ALSA: Remove transfer_ack_{begin,end} callbacks from struct snd_pcm_runtime
While there is nothing wrong with the transfer_ack_begin and
transfer_ack_end callbacks per-se, the last documented user was part of the
alsa-driver 0.5.12a package, which was released 14 years ago and even
predates the upstream integration of the ALSA core and has subsequently
been superseded by newer alsa-driver releases.

This seems to indicate that there is no need for having these callbacks and
they are just cruft that can be removed.
