2013-11-14Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-armLinus Torvalds
Pull ARM updates from Russell King: "Included in this series are: 1. BE8 (modern big endian) changes for ARM from Ben Dooks 2. big.Little support from Nicolas Pitre and Dave Martin 3. support for LPAE systems with all system memory above 4GB 4. Perf updates from Will Deacon 5. Additional prefetching and other performance improvements from Will. 6. Neon-optimised AES implementation fro Ard. 7. A number of smaller fixes scattered around the place. There is a rather horrid merge conflict in tools/perf - I was never notified of the conflict because it originally occurred between Will's tree and other stuff. Consequently I have a resolution which Will forwarded me, which I'll forward on immediately after sending this mail. The other notable thing is I'm expecting some build breakage in the crypto stuff on ARM only with Ard's AES patches. These were merged into a stable git branch which others had already pulled, so there's little I can do about this. The problem is caused because these patches have a dependency on some code in the crypto git tree - I tried requesting a branch I can pull to resolve these, and all I got each time from the crypto people was "we'll revert our patches then" which would only make things worse since I still don't have the dependent patches. I've no idea what's going on there or how to resolve that, and since I can't split these patches from the rest of this pull request, I'm rather stuck with pushing this as-is or reverting Ard's patches. Since it should "come out in the wash" I've left them in - the only build problems they seem to cause at the moment are with randconfigs, and since it's a new feature anyway. However, if by -rc1 the dependencies aren't in, I think it'd be best to revert Ard's patches" I resolved the perf conflict roughly as per the patch sent by Russell, but there may be some differences.

2013-08-25ARM: debug: provide generic option choices for 8250 and PL01x portsRussell King
Provide generic option choices for 8250 and PL01x UART ports; these can now be selected by UART type rather than asking about the platform. This means that a kernel configuration user can manually choose the various parameters of the debug UART without resorting to the platform having to encode the possible settings.

2013-07-22ARM: document DEBUG_UNCOMPRESS Kconfig optionRussell King
This non-user visible option lacked any kind of documentation. This is quite common for non-user visible options; certian people can't understand the point of documenting such options with help text. However, here we have a case in point: developers don't understand the option either, as they were thinking that when the option is not set, the decompressor should produce no output what so ever. This is incorrect, as the purpose of this option is to control whether a multiplatform kernel uses the kernel debugging macros to produce output or not. So let's document this via help rather than commentry to prevent others falling into this misunderstanding. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

These should have been in the 'soc' branch but were a little late * Support for the Exynos 5420 variant in mach-exynos, which is based on the other exynos branches to avoid conflicts. * Various small changes for sh-mobile, ux500 and davinci * Common clk support for MSM" * tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) ARM: ux500: bail out on alien cpus ARM: davinci: da850: adopt to pinctrl-single change for configuring multiple pins serial: sh-sci: Initialise variables before access in sci_set_termios() ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support ARM: msm: Migrate to common clock framework ARM: msm: Make proc_comm clock control into a platform driver ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver ARM: msm: Remove clock-7x30.h include file ARM: msm: Remove custom clk_set_{max,min}_rate() API ARM: msm: Remove custom clk_set_flags() API msm: iommu: Use clk_set_rate() instead of clk_set_min_rate() msm: iommu: Convert to clk_prepare/unprepare msm_sdcc: Convert to clk_prepare/unprepare usb: otg: msm: Convert to clk_prepare/unprepare msm_serial: Use devm_clk_get() and properly return errors msm_serial: Convert to clk_prepare/unprepare ...
2013-06-25Merge branch 'sti/soc' into next/lateOlof Johansson
From Srinivas Kandagatla <srinivas.kandagatla@st.com>: This patch-set adds basic support for STMicroelectronics STi series SOCs which includes STiH415 and STiH416 with B2000 and B2020 board support. STiH415 and STiH416 are dual-core ARM Cortex-A9 CPU, designed for use in Set-top-boxes. The SOC support is available in mach-sti which contains support code for STiH415, STiH416 SOCs including the generic board support. The reason for adding two SOCs at this patch set is to show that no new C code is required for second SOC(STiH416) support. * sti/soc: ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support Signed-off-by: Olof Johansson <olof@lixom.net>

Texas Instruments Keystone family of multi-core devices are based on ARM Cortex A15. Patch adds basic definitions for a new Keystone sub-architecture in ARM. The TCI66xxK2H Communications Infrastructure Keystone SoCs are member of the C66x family based on TI's new KeyStone 2 multi-core SoC Architecture designed specifically for high performance wireless and networking infrastructure applications. The SOCs contains many subsystems like Cortex A15 ARM CorePacs, C66XX DSP CorePacs, MSMC memory controller, Tera Net bus, IP Network, Navigator, Hyperlink, 1G/10G Ethernet, Radio layers and queue based communication systems.

2013-06-13arm: mvebu: add another earlyprintk Kconfig optionThomas Petazzoni
In order to support both old and new bootloaders, we add a new Kconfig option for the earlyprintk UART selection. The existing option allows to work with old bootloaders (that keep the internal registers mapped at 0xd0000000), while the newly introduced option allows to work with new bootloaders (that remap the internal registers at 0xf1000000).
