GPMC provides 2 interrupts for NAND use. i.e. fifoevent and termcount.
Use IRQ domain for this. NAND device tree node can then
get the necessary interrupts by using gpmc as the interrupt parent.
Legacy boot uses gpmc_get_client_irq to get the
NAND interrupts from the GPMC IRQ domain.
Get rid of custom bitmasks and use IRQ domain for that
as well.

That FIFO resizing logic was added to support OMAP5
ES1.0 which had a bogus default FIFO size. I can't
remember the exact size of default FIFO, but it was
less than one bulk superspeed packet (<1024) which
would prevent USB3 from ever working on OMAP5 ES1.0.
However, OMAP5 ES1.0 support has been dropped by
commit aa2f4b16f8 ("ARM: OMAP5: id: Remove ES1.0

Simply document new compatibility string.
As a previous patch adds a generic R-Car Gen2 compatibility string
there appears to be no need for a driver updates.
By documenting this compat string it may be used in DTSs shipped, for
example as part of ROMs. It must be used in conjunction with the Gen2
fallback compat string. At this time there are no known differences between
the r8a7792 IP block and that implemented by the driver for the Gen2
fallback compat string. Thus there is no need to update the driver as the
use of the Gen2 fallback compat string will activate the correct code in
the current driver while leaving the option for r8a7792-specific driver
code to be activated in an updated driver should the need arise.

Add fallback compatibility string for R-Car Gen 1 and 2.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, e.g. Gen 2 and 3. But beyond that it's unclear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.

The source and destination masters are reflecting buses or their layers to
where the different devices can be connected. The patch changes the master
names to reflect which one is related to which independently on the transfer
direction.
The outcome of the change is that the memory data width is now always limited
by a data width of the master which is dedicated to communicate to memory.
The patch will not break anything since all current users have the same data
width for all masters. Though it would be nice to revisit avr32 platforms to
check what is the actual hardware topology in use there. It seems that it has
one bus and two masters on it as stated by Table 8-2, that's why everything
works independently on the master in use. The purpose of the sequential patch
is to fix the driver for configuration of more than one bus.
The change is done in the assumption that src_master and dst_master are
reflecting a connection to the memory and peripheral correspondently on avr32
and otherwise on the rest.

This VDMA is a soft ip, which can be programmed to support
32 bit addressing or greater than 32 bit addressing.
When the VDMA ip is configured for 32 bit address space
the buffer address is specified by a single register
(0x5C for MM2S and 0xAC for S2MM channel).
When the VDMA core is configured for an address space greater
than 32 then each buffer address is specified by a combination of
two registers.
The first register specifies the LSB 32 bits of address,
while the next register specifies the MSB 32 bits of address.
For example, 5Ch will specify the LSB 32 bits while 60h will
specify the MSB 32 bits of the first start address.
So we need to program two registers at a time.
This patch adds the 64 bit addressing support to the vdma driver.

* Documentation
- Fix a typo in in_proximity_raw description.
- Add some missing docs for iio_buffer_access_funcs.
* Tools
- update iio_event_monitor names to match new stuff.
- make generic_buffer look for triggers ending in -trigger as we let these in
for a number of drivers a long time back and now it is a fairly common
option.
Drivers
* staging wide
- convert bare unsigned usage to unsigned int to comply with coding style.
* non staging wide:
- since boiler plate gpio handling of interrupts has been moved into the
ACPI core we don't need to include gpio/consumer.h in a load of drivers so
drop it.
* ad7606
- fix an endian casting sparse warning.
* ak8975
- fix a possible unitialized warning from gcc.
- drop and unused field left over from earlier cleanups
- fix a missing regulator_disable on exit.
* at91-sama5d2
- typo and indentation
- missing IOMEM dependency.
- cleanup mode register usage by avoidling erasing whole thing when changing
the sampling frequency.
* bmc150
- use the core demux and available_scan_masks to simplify buffer handling
- optimize the transfers in the trigger handler now we have a magic function
to emulate bulk reads (under circumstances met here). This matters with some
rather dumb i2c adapters in particular.
- use a single regmap_conf for all bus types as they were all the same.
* bmg160
- use the core demux and available_scan_masks to simplify the buffer handling
- optimize the transfers in the trigger handler now we have a magic funciton
to emulate bulk rads (under circumstances met here).
- drop gpio interrupt probing from the driver (ACPI) as now handled by the
ACPI core.
* ina2xx-adc
- update the CALIB register when RShunt changes.
- fix scale for VShunt - in reality this error canceled out when used.
* isl29028
- use regmap to retrieve the struct device instead of carrying a second
copy of it around.
* kxcjk-1013
- use core demux
- optimize i2c transfers in the trigger handler.
* mcp4531
- refactor to use a pointer to access model parameters instead of indexing
into the array each time.
* mma8452
- style fixes
- avoid swtiching to active whenever the config changes
- add missin i2c_device_id for mma8451
* mpu6050
- fix possible NULL dereference.
- fix the name / chip_id used when ACPI used (otherwise reports as NULL).
* ms5611
- fix a missing regulator_disable that left the regulator on during removal.
* mxc4005
- drop gpio interrupt handling for ACPI case from driver as the core now
handles this case.
* st-sensors
- note that there are only ever a maximum of 3 axis on current st-sensors
so just allocate a fixed sized buffer big enough for that.
* tpl0102
- change the i2c_check_functionality condition to bring it inline with other
IIO users as EOPNOTSUPP.
* tsl2563
- replace deprecated flush_scheduled_work

DT bindings should either use a unit address and a reg property
or none of them. Since either of them aren't really useful for
such a simple device like this one remove the unit address.

The ARM Versatile has an optional daughterboard, if this is
mounted, we need to be able to access its system controller.
Put in a documentation blurb for this.
