Geert Uytterhoeven 4ffb75c2dc ARM: nspire: Remove unneeded nspire_map_io()
nspire_map_io() just calls debug_ll_io_init().

If machine_desc.map_io is not set, devicemaps_init() in the
common ARM code will call debug_ll_io_init(), so nspire_map_io() and the
initialization of .map_io can be removed.

Linus Torvalds f64d6e2aaa DeviceTree update for 4.8:
- Removal of most of_platform_populate() calls in arch code. Now the DT
 core code calls it in the default case and platforms only need to call
 it if they have special needs.
 
 - Use pr_fmt on all the DT core print statements.
 
 - CoreSight binding doc improvements to block name descriptions.
 
 - Add dt_to_config script which can parse dts files and list
 corresponding kernel config options.
 
 - Fix memory leak hit with a PowerMac DT.
 
 - Correct a bunch of STMicro compatible strings to use the correct
 vendor prefix.
 
 - Fix DA9052 PMIC binding doc to match what is actually used in dts
 files.

Daniel Lezcano d683b9dcc8 clocksource/drivers/nspire: Add the COMPILE_TEST option
Change the Kconfig option logic to fullfil with the current approach.

A new Kconfig option is added, CONFIG_NSPIRE_TIMER and is selected by the
platform. Then the clocksource's Kconfig is changed to make this option
selectable by the user if the COMPILE_TEST option is set. Otherwise, it is
up to the platform's Kconfig to select the timer.

Linus Torvalds e88fa1b8b0 ARM: SoC cleanups for v4.6
A few simple cleanups across multiple platforms, not much standing out:
 
 - lpc32xx removes its private implementation of the clk API, after
   generic code was merged in 4.5
 - all unused Makefile.boot files get removed
 - a number of simplifications for shmobile
 - asm/clkdev.h gets replaced with the asm-generic version after
   all mach/clkdev.h implementations are gone

Luis R. Rodriguez f6e45661f9 dma, mm/pat: Rename dma_*_writecombine() to dma_*_wc()
Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.

Build tested successfully with allmodconfig.

The following Coccinelle SmPL patch was used for this simple
transformation:

@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@

-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)

@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@

-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)

@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@

-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)

We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

Uwe Kleine-König 543c5040f5 ARM: make arrays containing machine compatible strings const
The definition

	static const char *axxia_dt_match[] __initconst = {
		...

defines a changable array of constant strings. That is you must not do:

	*axxia_dt_match[0] = 'k';

but

	axxia_dt_match[0] = "different string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

	const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

Linus Torvalds dfc25e4503 ARM: SoC: cleanups for 3.15
These cleanup patches are mainly move stuff around and should all

 be based on top to avoid conflicts.
 
 Notable changes are:
 
 * We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
   longer used. (Uwe Kleine-König)
 * The Qualcomm MSM platform is split out into legacy mach-msm and
   new-style mach-qcom, to allow easier maintainance of the new
   hardware support without regressions. (Kumar Gala)
 * A rework of some of the Kconfig logic to simplify multiplatform
   support (Rob Herring)
 * Samsung Exynos gets closer to supporting multiplatform (Sachin
   Kamat and others)
 * mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
 * at91 gains some common clock framework support (Alexandre Belloni,
   Jean-Jacques Hiblot and other French people).
