3b2435192f MAINTAINERS: drop OMAP USB and MUSB maintainership
Now that I have switched to another company, I won't
be able to help by maintaining OMAP USB Support and/or
the MUSB driver.

OMAP USB Support is left Orphaned. MUSB's new
maintainer will be Bin Liu from Texas Instruments
who has accepted to take over starting with v4.6.

Pull networking fixes from David Miller:
 "Looks like a lot, but mostly driver fixes scattered all over as usual.

  Of note:

   1) Add conditional sched in nf conntrack in cleanup to avoid NMI
      watchdogs.  From Florian Westphal.

   2) Fix deadlock in nfnetlink cttimeout, also from Floarian.

   3) Fix handling of slaves in bonding ARP monitor validation, from Jay
      Vosburgh.

   4) Callers of ip_cmsg_send() are responsible for freeing IP options,
      some were not doing so.  Fix from Eric Dumazet.

   6) Fix vlan handling in mv88e6xxx DSA driver, from Vivien Didelot.

      Alexander Duyck.

   9) SKB leaks and other problems in arc_emac driver, from Alexander
      Kochetkov.

  10) tcp_v4_inbound_md5_hash() releases listener socket instead of
      request socket on error path, oops.  Fix from Eric Dumazet.

  11) Missing socket release in pppoe_rcv_core() that seems to have
      existed basically forever.  From Guillaume Nault.

  12) Missing slave_dev unregister in dsa_slave_create() error path,
      from Florian Fainelli.

  15) Fix races in tcp/dccp listener socket dismantle, from Eric
      Dumazet.

  16) Don't set IFF_TX_SKB_SHARING in vxlan, geneve, or GRE, it's not
      legal.  These drivers modify the SKB on transmit.  From Jiri Benc.

  17) Fix regression in the initialziation of netdev->tx_queue_len.
      From Phil Sutter.

  18) Missing unlock in tipc_nl_add_bc_link() error path, from Insu Yun.

1926e54f11 MAINTAINERS: Update mailing list for Renesas ARM64 SoC Development
Update the mailing list used for development of support for ARM64
Renesas SoCs.

This is a follow-up for a similar change for other Renesas SoCs and
drivers uses by Renesas SoCs.  The ARM64 SoC entry was not updated in
that patch as it was not yet present in mainline.

The motivation for the mailing list update is that Renesas SoCs are now
much wider than the SH architecture and there is some desire from some
for the linux-sh list to refocus on discussion of the work on the SH
architecture.

   - new driver supporting ADC0831, ADC0832, ADC0834 and ADC0838 ADCs.
 * TI ads1015
   - new driver, note that there is an existing hwmon driver. The long term
     intention is to probably remove the hwmon driver but for now we just have
     guards in place to ensure this driver is not built if that one is enabled.
 * TI afe4403
   - new driver for this heart rate monitor / pulse oximeter front end chip.
 * TI afe4404
   - new driver for this heart rate monitor / pulse oximeter front end chip.
 
 Staging Graduations
 * mxs-lradc
   - A combined general purpose and touch screen (input) device driver.
     Originally held in staging to allow reworking into and MFD but as
     that wasn't happening and isn't an absolute requirement we are moving
     it out of staging.
 
 Driver new features
 * ms5611
   - triggered buffer support
   - IIO_CHAN_INFO_SCALE to aid the triggered buffer support.
 
 Driver cleanups / reworks / fixes
 * ad5064
   - Use an enum for the register map layout to allow support of additional
     chips (precursor to the new support listed above).
   - Structural driver changes to allow support of the slightly different
     handling for the ltc parts above.
 * ad5933
   - drop an exceptional & unnecessary for a function pointer.
 * ad7606
   - Cleanup the repeated copies of pm ops.
   - consolidate the various channels specs via a sport of rearranging so only
     one version is needed.
 * atlas ph sensor
   - add select IRQ_WORK
 * hmc8543 (soon to move out of staging)
   - Comment style fixes
   - functionality of suspend and resume was swapped.
 * spear-adc
   - use devm_clk_dev instead of managing the clk lifetime by hand.
 
 Core
 * Use new dmaengine_terminate_sync call to avoid a theoretical race.
 * Fix docs for mlock in struct iio_dev as it is correctly taken in some
   drivers (docs used to say for core only).
 * Add a helper function for calculating the scan index storage size within
   the core cutting out some cut and paste versions of the same code.

97a445dad3 iio: Add IIO support for the DAC on the Apex Embedded Systems STX104
The Apex Embedded Systems STX104 is a 16-channel 16-bit analog input and
2-channel 16-bit analog output PC/104 card. The STX104 incorporates a
large one mega-sample FIFO.

This driver provides IIO support for the 2-channel DAC on the STX104.
The base port addresses for the devices may be configured via the "base"
module parameter array.

96173cc6a4 regulator: Rename files for max77686 and max77802 drivers
The max77686 and max77802 regulator drivers are for sub-devices of a MFD
driver for some PMIC blocks. But the same object file name (max77686.o)
was used for both the common MFD driver and the max77686 regulator one.

This confuses kbuild if both drivers are built as module causing the MFD
driver to not be copied when installing the modules.

Also, max77{686,802} are a quite generic name for MFD subdevices drivers
so it is better to rename them to max77{686,802}-regulator like it's the
case for most regulator drivers.

3c702e9987 gpio: add a userspace chardev ABI for GPIOs
A new chardev that is to be used for userspace GPIO access is
added in this patch. It is intended to gradually replace the
horribly broken sysfs ABI.

Using a chardev has many upsides:

- All operations are per-gpiochip, which is the actual
  device underlying the GPIOs, making us tie in to the
  kernel device model properly.

- Hotpluggable GPIO controllers can come and go, as this
  kind of problem has been know to userspace for character
  devices since ages, and if a gpiochip handle is held in
  userspace we know we will break something, whereas the
  sysfs is stateless.

- The one-value-per-file rule of sysfs is really hard to
  maintain when you want to twist more than one knob at a time,
  for example have in-kernel APIs to switch several GPIO
  lines at the same time, and this will be possible to do
  with a single ioctl() from userspace, saving a lot of
  context switching.

We also need to add a new bus type for GPIO. This is
necessary for example for userspace coldplug, where sysfs is
traversed to find the boot-time device nodes and create the
character devices in /dev.

This new chardev ABI is *non* *optional* and can be counted
on to be present in the future, emphasizing the preference
of this ABI.

The ABI only implements one single ioctl() to get the name
and number of GPIO lines of a chip. Even this is debatable:
see it as a minimal example for review. This ABI shall be
ruthlessly reviewed and etched in stone.

The old /sys/class/gpio is still optional to compile in,
but will be deprecated.

Unique device IDs are created using IDR, which is overkill
and insanely scalable, but also well tested.

API/ABI changes.  However, catching all changes in Documentation/ABI/
and include/uapi/ produces a large volume of mail to linux-api, rather
than only API/ABI changes.  Drop those two entries, but leave
include/linux/syscalls.h and kernel/sys_ni.c to catch syscall-related
changes.
