f747a1fe78 regulator: pwm-regulator: Remove obsoleted property
In "[3d7ef30] regulator: pwm-regulator: Simplify voltage to duty-cycle
call" we stopped using max_duty_cycle, so we can retire it from device
data and DT.

There is no need to deprecate this property, as it hasn't hit Mainline
yet.

3692db3a90 regulator: max8973: add support to configure ETR from DT
The MAX8973/MAX77621 feature an Enhanced Transient Response(ETR)
circuit that is enabled through software. The enhanced transient
response reduces the voltage droop during large load steps by
temporarily allowing all three phases to fire in unison, slewing
total inductor current faster than would normally be possible if
all three phases continued to operate 120deg out of phase. The
enhanced transient response detector features two selectable
sensitivity settings, which select the output voltage slew rate
during load transients that triggers the ETR circuit. The sensitivity
of the ETR detector is set by the CKADV[1:0] bits in the CONTROL2
register.

Add support to configure the ETR through platform data from DT.
Update the DT binding document accordingly.

Maximum speed supported by spfi is limited to 1/4 of the spfi clock.

But in some SoCs the maximum speed supported by the spfi block can
be limited to less than 1/4 of the spfi clock. In such cases we have
to define the limit in the device tree so that the driver can pick
it up.

ARCH_CFLAGS variables that are appended to the respective kbuild
variables. The user still has the final say via the KCPPFLAGS, KAFLAGS

5c755fe142 Merge branch 'for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/nab/target-pending
Pull SCSI target updates from Nicholas Bellinger:
 "It's been a busy development cycle for target-core in a number of
  different areas.

  The fabric API usage for se_node_acl allocation is now within
  target-core code, dropping the external API callers for all fabric
  drivers tree-wide.

  There is a new conversion to RCU hlists for se_node_acl and
  se_portal_group LUN mappings, that turns fast-past LUN lookup into a
  completely lockless code-path.  It also removes the original
  hard-coded limitation of 256 LUNs per fabric endpoint.

  The configfs attributes for backends can now be shared between core
  and driver code, allowing existing drivers to use common code while
  still allowing flexibility for new backend provided attributes.

  The highlights include:

   - Merge sbc_verify_dif_* into common code (sagi)
   - Remove iscsi-target support for obsolete IFMarker/OFMarker
     (Christophe Vu-Brugier)
   - Add bidi support in target/user backend (ilias + vangelis + agover)
   - Move se_node_acl allocation into target-core code (hch)
   - Add crc_t10dif_update common helper (akinobu + mkp)
   - Handle target-core odd SGL mapping for data transfer memory
     (akinobu)
   - Move transport ID handling into target-core (hch)
   - Move task tag into struct se_cmd + support 64-bit tags (bart)
   - Convert se_node_acl->device_list[] to RCU hlist (nab + hch +
     paulmck)
   - Convert se_portal_group->tpg_lun_list[] to RCU hlist (nab + hch +
     paulmck)
   - Simplify target backend driver registration (hch)
   - Consolidate + simplify target backend attribute implementations
     (hch + nab)
   - Subsume se_port + t10_alua_tg_pt_gp_member into se_lun (hch)
   - Drop lun_sep_lock for se_lun->lun_se_dev RCU usage (hch + nab)
   - Drop unnecessary core_tpg_register TFO parameter (nab)
   - Use 64-bit LUNs tree-wide (hannes)

9bdc771f2c Merge tag 'acpica-4.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPICA updates from Rafael Wysocki:
 "Additional ACPICA material for v4.2-rc1

  This will update the ACPICA code in the kernel to upstream revision
  20150619 (a bug-fix release mostly including stable-candidate fixes)
  and restore an earlier ACPICA commit that had to be reverted due to a
  regression introduced by it (the regression is addressed by
  blacklisting the only known system affected by it to date).

  The only new feature added by this update is the support for
  overriding objects in the ACPI namespace and a new ACPI table that can
  be used for that called the Override System Definition Table (OSDT).
  That should allow us to "patch" the ACPI namespace built from
  incomplete or incorrect ACPI System Definition tables (DSDT, SSDT)
  during system startup without the need to provide replacements for all
  of those tables in the future.

  Specifics:

   - Fix system resume problems related to 32-bit and 64-bit versions of
     the Firmware ACPI Control Structure (FACS) in the firmare (Lv
     Zheng)

   - Fix double initialization of the FACS (Lv Zheng)

   - Add _CLS object processing code to ACPICA (Suravee Suthikulpanit)

   - Add support for the (currently missing) new GIC version field in
     the Multiple APIC Description Table (MADT) (Hanjun Guo)

   - Add support for overriding objects in the ACPI namespace to ACPICA
     and OSDT support (Lv Zheng, Bob Moore, Zhang Rui)

   - Updates related to the TCPA and TPM2 ACPI tables (Bob Moore)

   - Restore the commit modifying _REV to always return "2" (as required
     by ACPI 6) and add a blacklisting mechanism for systems that may be
     affected by that change (Rafael J Wysocki)

   - Assorted fixes and cleanups (Bob Moore, Lv Zheng, Sascha Wildner)"

18d78b64fd ACPI / init: Make it possible to override _REV
The platform firmware on some systems expects Linux to return "5" as
the supported ACPI revision which makes it expose system configuration
information in a special way.

For example, based on what ACPI exports as the supported revision,
Dell XPS 13 (2015) configures its audio device to either work in HDA
mode or in I2S mode, where the former is supposed to be used on Linux
until the latter is fully supported (in the kernel as well as in user
space).

Since ACPI 6 mandates that _REV should return "2" if ACPI 2 or later
is supported by the OS, a subsequent change will make that happen, so
make it possible to override that on systems where "5" is expected to
be returned for Linux to work correctly one them (such as the Dell
machine mentioned above).

Pull fuse updates from Miklos Szeredi:
 "This is the start of improving fuse scalability.

  An input queue and a processing queue is split out from the monolithic
  fuse connection, each of those having their own spinlock.  The end of
  the patchset adds the ability to clone a fuse connection.  This means,
  that instead of having to read/write requests/answers on a single fuse
  device fd, the fuse daemon can have multiple distinct file descriptors
  open.  Each of those can be used to receive requests and send answers,
  currently the only constraint is that a request must be answered on
  the same fd as it was read from.

  This can be extended further to allow binding a device clone to a
  specific CPU or NUMA node.

  Based on a patchset by Srinivas Eeda and Ashish Samant.  Thanks to
  Ashish for the review of this series"
