Jonathan Cameron db8fa7311d iio:adc:vf610 ensure correct handing of interruption of wait for completion
Issue highlighted by smatch warning:

CHECK   drivers/iio/adc/vf610_adc.c
drivers/iio/adc/vf610_adc.c:466 vf610_read_raw() warn: unsigned 'ret' is never less than zero.

As wait_for_completion_interruptible_timeout can return -ERESTARTSTSYS, if
interrupted, ret must be signed.

Lars-Peter Clausen bdc8cda1d0 iio:adc: Add Xilinx XADC driver
The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This driver
supports both interfaces and internally has a small abstraction layer that hides
the specifics of these interfaces from the main driver logic.

The ADC has a couple of internal channels which are used for voltage and
temperature monitoring of the FPGA as well as one primary and up to 16 channels
auxiliary channels for measuring external voltages. The external auxiliary
channels can either be directly connected each to one physical pin on the FPGA
or they can make use of an external multiplexer which is responsible for
multiplexing the external signals onto one pair of physical pins.

The voltage and temperature monitoring channels also have an event capability
which allows to generate a interrupt when their value falls below or raises
above a set threshold.

Buffered sampling mode is supported by the driver, but only for AXI-XADC since
the ZYNQ XADC interface does not have capabilities for supporting buffer mode
(no end-of-conversion interrupt). If buffered mode is supported the driver will
register two triggers. One "xadc-samplerate" trigger which will generate samples
with the configured samplerate. And one "xadc-convst" trigger which will
generate one sample each time the CONVST (conversion start) signal is asserted.

Lars-Peter Clausen 588858c4df devicetree: Add Xilinx XADC binding documentation
The Xilinx XADC is a ADC that can be found in the series 7 FPGAs from Xilinx.
The XADC has a DRP interface for communication. Currently two different
frontends for the DRP interface exist. One that is only available on the ZYNQ
family as a hardmacro in the SoC portion of the ZYNQ. The other one is available
on all series 7 platforms and is a softmacro with a AXI interface. This binding
document describes the bindings for both of them since the bindings are very
similar.

Each of them needs:
	* A address range where the registers are mapped
	* An interrupt number for the device interrupt
	* A clock. For the the ZYNQ hardmacro interface this is the modules PCAP
	  clock, for the AXI softmacro it is the AXI bus interface clock.

Additionally the bindings specify whether an external multiplexer is used and in
which mode it is used. The devicetree bindings also describe which external
channels are connected and in which configuration.

osc_extent_wait can be stuck in scenario like this:

1) thread-1 held an active extent
2) thread-2 called flush cache, and marked this extent as "urgent"
   and "sync_wait"
3) thread-3 wants to write to the same extent, osc_extent_find will
   get "conflict" because this extent is "sync_wait", so it starts
   to wait...
4) cl_writeback_work has been scheduled by thread-4 to write some
   other extents, it has sent RPCs but not returned yet.
5) thread-1 finished his work, and called osc_extent_release()->
   osc_io_unplug_async()->ptlrpcd_queue_work(), but found
   cl_writeback_work is still running, so it's ignored (-EBUSY)
6) thread-3 is stuck because nobody will wake him up.

This patch allows ptlrpcd_work to be rescheduled, so it will not
miss request anymore

John L. Hammond add882a8b5 lustre/mdc: fix bad ERR_PTR usage in mdc_locks.c
In mdc_intent_open_pack() return an ERR_PTR() rather than NULL when
ldlm_prep_enqueue_req() fails. In mdc_intent_getattr_async() check the
return value of mdc_intent_getattr_pack() using IS_ERR(). Clean up the
includes in mdc_locks.c.

John L. Hammond ec9bca9c51 lustre/clio: honor O_NOATIME
Add a ci_noatime bit to struct cl_io. In ll_io_init() set this bit if
O_NOATIME is set in f_flags. Ensure that this bit is propagated down
to lower layers. In osc_io_read_start() don't update atime if this bit
is set. Add sanity test 39n to check that passing O_NOATIME to open()
is honored.

Alexey Lyashkov 6caea2f980 lustre/mdc: use ibits_known mask for lock match
Before revalidating a lock on the client, mask the lock bits against
the lock bits supported by the server (ibits_known), so newer clients
will find valid locks given by older server versions.

Greg Kroah-Hartman d3dae4ad18 Fourth set of IIO fixes for the 3.14 kernel.
A single line patch fixing a regression that was introduced in 3.13 in the
 reworking of the mxs touch screen and ADC drivers to be interrupt rather
 than polling driven.  It resulted in a stray double reporting of the release
 coordinate in the touch screen driver.  The bug lay in the adc side
 of the driver which left the statemachine in the wrong state.
