12c957dc94 staging: unisys: visorbus: allow visorhba device to be used for kdump
This patch saves off the create_bus and create_device controlvm messages
for the visorhba device, so that they can be resurrected and used in the
kdump kernel.

After this patch, a crash dump can be generated using:

    # service kdump start
    # echo 1 > /proc/sys/kernel/sysrq
    # echo c > /proc/sysrq-trigger

c732623b0b staging: unisys: visorbus: tolerate larger-than-expected controlvm channel
Use the dynamic size of the controlvm channel (struct channel_header.size)
instead of the statically computed sizeof(struct controlvm_channel) when
determining the valid bounds for visorchannel_read() and
visorchannel_write().

This prevents an observed problem where kdump was failing because
controlvm_channel.local_crash_msg_offset was pointing beyond the statically
computed size of the channel, even though the channel was physically large
enough.  This was causing visorchannel_read() to unecessarily fail, because
we thought we were attempting to access memory outside of the channel.

a8deaef370 staging: unisys: visorbus: fix payload memory usage in controlvm channel
Previously if controlvm message payloads (indicated in controlvm message
via struct controlvm_message.hdr.payload_vm_offset) were contained within
the bounds of the channel memory, we would fail to process any controlvm
message that contained payload data.  Reason is, the request_mem_region()
would fail, because it overlapped the channel memory.  Since
request_mem_region() doesn't actually serve a functional purpose anyway,
this was simply removed.

Drop visornic_timeout_reset_workqueue by using system_wq.

Since there is only one work item per devdata and different
devdatas do not need to be ordered, increase of concurrency

bbb7bace03 snic: correctly check for array overrun on overly long version number
The snic version number is expected to be 4 decimals in the form like a
netmask string with each number stored in an element in array v.
However, there is an off-by-one check on the number of elements in v
allowing one to pass a 5 decimal version number causing v[4] to be
referenced, causing a buffer overrun.  Fix the off-by-one error by
comparing to i > 3 rather than 4.

a6d24143fc qlogicpti: Return correct error code
The return value of of_ioremap on failure should be -ENODEV and not
-1.

Found using Coccinelle. A simplified version of the semantic patch
used is:

//<smpl>
@@
expression *e;
@@

e = of_ioremap(...);
if (e == NULL) {
...
return
- -1
+ -ENODEV
;
}
//</smpl>

The single call site only checks that the return value is less than 0,
hence no change is required at the call site.

Pass the channel information to the util drivers that need to defer

the following issue reported by Vitaly:

Commit 3cace4a616 ("Drivers: hv: utils: run polling callback always in
interrupt context") removed direct *_transaction.state = HVUTIL_READY
assignments from *_handle_handshake() functions introducing the following
race: if a userspace daemon connects before we get first non-negotiation
request from the server hv_poll_channel() won't set transaction state to
HVUTIL_READY as (!channel) condition will fail, we set it to non-NULL on
the first real request from the server.

Update extcon for 4.6

Detailed description for patchset:
1. Add new EXTCON_CHG_USB_SDP type
- SDP (Standard Downstream Port) USB Charging Port
  means the charging connector.a

2. Add the VBUS detection by using GPIO on extcon-palmas
- Beaglex15 board uses the extcon-palmas driver
  But, beaglex15 board need the GPIO support for VBUS
  detection.

3. Fix the minor issue of extcon drivers

949024d670 ARM: dts: porter: remove enable prop from HS-USB device node
In  the final versions of the Porter board (called "PORTER_C") Renesas
decided to get rid  of the Maxim Integrated MAX3355 OTG chip and didn't
add any other provision to differ the host/gadget mode, so we'll have to
remove  no longer valid "renesas,enable-gpio" property from the HS-USB
device node.  Hopefully, the earlier revisions of the board were never
seen in the wild...

ec3c13e4ac Third set of IIO new device support, features and cleanups for the 4.6 cycle.
Good to see several new contributors in this set - and more generally a
 number of new 'faces' over this whole cycle.
 
 Staging movements
 * hmc5843
   - out of staging.
 * periodic RTC trigger
   - driver dropped.  This is an ancient driver (brings back some memories ;)
   that was always somewhat of a bodge. Originally there was a driver that
   never went into mainline that supported large numbers of periodict timers
   on the PXA270 via this route. Discussions to have a generic periodic
   timer subsystem never went anywhere.  At the time RTC periodic
   interrupts were real - now they are emulated using high resolution
   timers so with the HRT driver this has become pointless.
 
 New device support
 * mpu6050 driver
   - Add support for the mpu6500.
 * TI tpl0102 potentiometer
   - new driver.
 * Vybrid SoC DAC
   - new driver.  The ADC on this SoC has been supported for a while, this
     adds a separate driver for the DAC.
 
 New Features
 * hmc5844
   - Attributes to configure the bias current (typically part of a self test)
     This could be done before via a somewhat obscure custom interface.
     This at least makes it easy to tell what is going on.
   - Document all custom attributes.
 * mpu6050
   - Add support for calibration offset control and readback.
 * ms5611
   - power regulator support.  This is always one that gets added the
     first time someone has a board that needs it.  Here it was needed,
     hence it was added.
 
 Cleanups / minor fixes
 * tree wide
   - clean up all the myriad different return values in response to a
     failure of i2c_check_functionality.  After discussions everyone seemed
     happy wiht -EOPNOTSUPP which seems to describe the situation well.
     I encouraged a tree wide cleanup to set a good example in future for
     this.
 * core
   - Typos in the iio_event_spec documentation in iio.h
 * afe4403
   - select REGMAP_SPI to avoid dependency issues
   - mark suspend/resume as __maybe_unused to avoid warnings
 * afe4404
   - mark suspend/resume as __maybe_unused to avoid warnings
 * atlas-ph-sensor
   - switch the regmap cache type from linear to rbtree to gain reading of
     registers on initial startup.  It's not immediately obvious, but
     regmap flat is meant for high performances cases so doesn't read these
     registers.
   - use regmap_bulk_read in one case where it was using
     i2c_smbus_read_i2c_block_data directly (unlike everything else that was
     through regmap).
 * ina2xx
   - stype cleanups (lots of them!)
 * isl29018
   - Get the struct device back from regmap rather than storing another
     copy of it in the private data.  This cleanup makes sense in a number
     of other drivers so patches may well follow.
 * mpu6050
   - style cleanups (lots of them!)
   - improved return value handling
   - use usleep_range to avoid the usual issues with very short msleeps.
   - add some missing documentation.
 * ms5611
   - use the probed device name for the device rather than the driver name.
   - select IIO_BUFFER to avoid dependency issues
 * palmas
   - drop IRQF_EARLY_RESUME as no longer needed after genirq changes.

21330497f3 clk: ti: Add support for dm814x ADPLL
On dm814x we have 13 ADPLLs with 3 to 4 outputs on each. The
ADPLLs have several dividers and muxes controlled by a shared
control register for each PLL.

Note that for the clocks to work as device drivers for booting on
dm814x, this patch depends on "ARM: OMAP2+: Change core_initcall
levels to postcore_initcall" that has already been merged.

Also note that this patch does not implement clk_set_rate for the
PLL, that will be posted later on when available.

Pull d_inode/d_flags race fix from Al Viro.

I love this fix.  Not only does it fix the race in the dentry type
handling, it entirely gets rid of the nasty and subtle memory ordering
rules for d_type and d_inode, and replaces them with the basic dentry
locking rules (sequence numbers under RCU, d_lock elsewhere).
