Linus Torvalds 10fdfee7f7 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input updates from Dmitry Torokhov:
 "The most notable item is addition of support for Synaptics RMI4
  protocol which is native protocol for all current Synaptics devices
  (touchscreens, touchpads).  In later releases we'll switch devices
  using HID and PS/2 protocol emulation to RMI4.

  You will also get:
   - BYD PS/2 touchpad protocol support for psmouse
   - MELFAS MIP4 Touchscreen driver
   - rotary encoder was moved away from legacy platform data and to
     generic device properties API, devm_* API, and can now handle
     encoders using more than 2 GPIOs
   - Cypress touchpad driver was switched to devm_* API and device
     properties
   - other assorted driver fixes"

Stefan Agner 4774f40093 Input: ad7879 - move header to platform_data directory
The header file is used by the SPI and I2C variant of the driver.
Therefore, move it to a more generic place under platform_data.

Bjorn Helgaas 288e6eaa06 gpio: Include linux/gpio.h instead of asm/gpio.h
Most arches have an asm/gpio.h that merely includes linux/gpio.h.  The
others select ARCH_HAVE_CUSTOM_GPIO_H, and when that's selected,
linux/gpio.h includes asm/gpio.h.

Therefore, code should include linux/gpio.h instead of including asm/gpio.h
directly.

Remove includes of asm/gpio.h, adding an include of linux/gpio.h when
necessary.

This is a follow-on to 7563bbf89d ("gpiolib/arches: Centralise
bolierplate asm/gpio.h").

Paul Gortmaker fa83af7e8f blackfin: fix ifdef fustercluck in mach-bf538/boards/ezkit.c
This file has lots and lots of ifdef, around structure decls
and structure usages.  The failure issue was that we would
build the BF538-EZKIT_defconfig and get:

 arch/blackfin/mach-bf538/boards/ezkit.c:924:3: error: 'bfin_lq035q1_device'
 undeclared here (not in a function)

even though the same ifdef _appeared_ to enable both the struct
declaration and the code that used it.  Yet cpp was telling us we
didn't have the struct, but we still had the usage of it.

However, _appeared_ is the operative word.  After marking all the
anonymous #endif with their parent #ifdef config options, it was
_then_ clear that there was a misplaced #endif that was hiding
the struct declaration.

The real guts of the patch boils down to this:

-#endif
+#endif /* CONFIG_MTD_M25P80 */
+#endif /* CONFIG_SPI_BFIN5XX */
 [...]
-#endif  /* spi master and devices */

but since I had to tag the #endif with their respective #ifdef
options to find this misplaced SPI endif, it would be silly to
then go and delete them all.  So they stay.

Mike Frysinger 2f7d63f909 Blackfin: boards: clean up redundant/dead spi resources
The default for the Blackfin SPI driver is 8 bits and dma disabled,
so many of the bfin5xx_spi_chip resources are redundant.  So punt
those parts.

Further, drivers should themselves be declaring 16 bit transfers,
so for those that do, and for the ones which no longer do 16 bit
transfers, drop the bfin5xx_spi_chip resources.

Mike Frysinger 1a5c226528 Blackfin: clean up mach header includes
The main asm/blackfin.h header will pull in mach/blackfin.h to get
all the fun Blackfin defines.  So having any of the sub-mach headers
trying to include asm/blackfin.h makes no sense -- punt it.

The mach/blackfin.h header takes care of including the part-specific
def headers which in turn will include any other needed def file.
Similarly, it takes care of pulling in the part-specific cdef header.
So move this logic out of the blackfin.h when necessary.

Further, make sure the cdef headers do not waste time including the
def headers again.

Since all parts need the common def/cdef headers, move this logic
out of the part-specific headers and into the mach/blackfin.h file.

Finally, we need to split the BF539 def header since the BF538 does
not have MXVR and we don't want to expose those MMRs.

So now all parts should have the same behavior:
	mach/blackfin.h
		asm/def_LPBlackfin.h
		part-specific def.h
		if ! asm
			asm/cdef_LPBlackfin.h
			part-specific cdef.h
And the sub def/cdef headers only tail into what they need.

and then fixing up asm/irqflags.h manually.
