2016-07-14ARM: s3c64xx: avoid warning about 'struct device_node'Arnd Bergmann1-0/+1
The change to simplify of_platform_populate() had an unintended side-effect of introducing a build warning on s3c64xx: In file included from arch/arm/mach-s3c64xx/mach-s3c64xx-dt.c:18:0: arch/arm/mach-s3c64xx/common.h:27:30: error: 'struct device_node' declared inside parameter list will not be visible outside of this definition or declaration [-Werror] This adds a forward-declaration for the structure name in the header to avoid the warning.

2016-06-28ARM: imx: remove cpu_is_mx*()Arnd Bergmann2-103/+0
The mxc_cpu_type and cpu_is_mx() logic is largely unused, and the few remaining users were easy to convert into simpler code. Now that they are gone, we can remove all those macros as well. The related cpu_is_imx6*() set of function unfortunately is harder to remove, so those are staying around for now.

2016-06-28ARM: imx: remove last call to cpu_is_mx5*Arnd Bergmann1-8/+0
The check for cpu_is_mx51/cpu_is_mx53() in mx51_revision()/mx53_revision() is just a safety precaution, but there are only two callers of this are using it only on the correct CPUs, and none of the other respective functions have this extra check. Removing these lets us kill off the cpu_is_* functions. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
2016-06-28ARM: imx: rework mx27_pm_init() callArnd Bergmann4-7/+5
mx27_pm_init() uses its own initcall, unlike all of the other functions like it. Replacing the initcall with a .init_late() callback makes imx27 more like the others and lets us remove the last caller of cpu_is_mx27().

2016-06-28ARM: imx: deconstruct mx3_idleArnd Bergmann3-44/+24
The imx31 and imx35 idle functions are almost the same, but we currently have to check the cpu type every time. This can be simplified by moving the logic from mx3_cpu_lp_set() into two separate idle functions, removing the last user of cpu_is_mx35.

2016-06-28ARM: imx: deconstruct mxc_rnga initializationArnd Bergmann5-61/+18
The rnga platform device is initialized for all imx31 machines from its own initcall, but is never initialized anywhere else. This moves the platform device creation into both the imx31 dt and non-dt machine init sequences, which has basically the exact same effect as before, but makes it more obvious what is going on, while reducing the amount of code and removing the last user of cpu_is_mx31().

2016-06-21ARM: i.MX: Do not explicitly call l2x0_of_init()Andrey Smirnov5-15/+13
There's no need to explicitly call l2x0_of_init() since it will be called as a part of init_IRQ() (see arch/arm/kernel/irq.c for details). This way we can simplify imx_init_l2cache() and ditch the call to it on i.MX35 (which does not claim compatibility with "arm,pl310-cache") alltogether.

2016-06-21ARM: i.MX: system.c: Tweak prefetch settings for performanceAndrey Smirnov1-2/+6
Update Prefetch Control Register settings to match that of Freescale's Linux tree. As the commit e3addf1b773964eac7f797e8538c69481be4279c states (author Nitin Garg): "... set Prefetch offset to 15, since it improves memcpy performance by 35%. Don't enable Incr double Linefill enable since it adversely affects memcpy performance by about 32MB/s and reads by 90MB/s. Tested with 4K to 16MB sized src and dst aligned buffer..."

2016-06-21ARM: i.MX: system.c: Remove redundant errata 752271 codeAndrey Smirnov1-11/+0
Applying a fix for ARM errata 752271 would already be taken care by a call to a 'fixup' hook as a part of l2x0_of_init() -> __l2c_init() call chain. Moreso the code in 'fixup' function would do that based on the PL310's revsion information, whereas removed code does so based on SoC version which does not work very well on i.MX6Q+ which identifies itself as i.MX6Q as well but is not affected by 752271.

2016-06-03ARM: do away with ARCH_[WANT_OPTIONAL|REQUIRE]_GPIOLIBLinus Walleij33-55/+52
This replaces: - "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB" as this can now be selected directly. - "select ARCH_WANT_OPTIONAL_GPIOLIB" with no dependency: GPIOLIB is now selectable by everyone, so we need not declare our intent to select it. When ordering the symbols the following rationale was used: if the selects were in alphabetical order, I moved select GPIOLIB to be in alphabetical order, but if the selects were not maintained in alphabetical order, I just replaced "select ARCH_REQUIRE_GPIOLIB" with "select GPIOLIB".

2016-06-03ARM: uniphier: drop code for old DT bindingMasahiro Yamada1-13/+5
Commit 307d40c56b0c ("ARM: uniphier: rework SMP code to support new System Bus binding") added a new DT binding for SMP code, but still kept old code for the backward compatibility. Linux 4.6 was out with both bindings supported, so it should not hurt to drop the old code now. Moreover, the mainline code are currently not used for any of our products, so this change has no impact on our customers in any way.

2016-06-03ARM: s3c24xx: Sort cpufreq tablesViresh Kumar3-1/+4
Some later changes in cpufreq core require these tables to be sorted based on ascending order of their frequencies. There was only one offender. Fix it and add comments over the arrays.

2016-05-29Rename other copy of hash_string to hashlen_stringGeorge Spelvin1-2/+2
The original name was simply hash_string(), but that conflicted with a function with that name in drivers/base/power/trace.c, and I decided that calling it "hashlen_" was better anyway. But you have to do it in two places.

2016-05-29hpfs: implement the show_options methodMikulas Patocka1-11/+32
The HPFS filesystem used generic_show_options to produce string that is displayed in /proc/mounts. However, there is a problem that the options may disappear after remount. If we mount the filesystem with option1 and then remount it with option2, /proc/mounts should show both option1 and option2, however it only shows option2 because the whole option string is replaced with replace_mount_options in hpfs_remount_fs. To fix this bug, implement the hpfs_show_options function that prints options that are currently selected.
