[PATCH v12 00/15] arm: Fix DEBUG_LL for multi-platform kernels (without PL01X)

by Daniel Thompson

This patchset removes some single-platform compatibility tricks related to DEBUG_LL and, as a result, allows multi_v7_defconfig derived builds to enable DEBUG_LL. Currently the user selected kbuild setting is ignored and the PL01X's DEBUG_LL stub is silently selected instead. This is a pain if your hardware doesn't have this cell, not least because it takes a little time to figure out that kbuild built the wrong code. Warning: silentoldconfig on PL011 single platforms will result in DEBUG_LL being directed at ICEDCC rather than PL011. This should only affect silentoldconfig since oldconfig prompts and the defconfigs have been updated to avoid this problem. Changes since v11: - Fixed sort order of Kconfig symbols (review of Russell King) - Reviewed all defconfigs for the selection of DEBUG_UART_NONE. All identified have 8250-based UARTs and are switched to DEBUG_LL_UART_8250 (review of Arnd Bergmann). - Fixed regression in the netx macros (bad setting of \rp and \rv. - Rebased on latest mainline (v3.18-rc1). Note that two patches from v11 were merged upstream and are no longer included here. - Added a trivial fix to the defaults list for DEBUG_UART_PHYS which came to my attention as a merge conflict. Changes since v10: - Fixed typos in the omap1 config help texts (review of Aaro Koskinen). Changes since v9: - Removed a spuriously introduced (and unused) config variable from the netx patch (review of Paul Bolle). - Fix netx macro to ensure \rv is correctly initialized. - Rebased on v3.17rc4. Changes since v8: - Regenerated patch series with --find-renames to properly track code movement. Changes since v7: - Killed DEBUG_LL_UART_NONE completely and migrated over the four remaining platforms that relied on this (Arnd Bergmann, Russell King). This fixes some problems with oldconfig builds. - Rebased on latest mainline (v3.17rc1). Changes since v6: - Removed a patch to limit DEBUG_LL_UART_NONE to platforms that support it because it almost time to drop DEBUG_LL_UART_NONE anyway (only four platforms still use it). - Rebased on latest mainline (v3.16rc3). Changes since v5: - Shortened the list of platforms that can select DEBUG_LL_UART_NONE (changes Arnd Bergmann) - Rebased on latest mainline (v3.15rc7). Changes since v4: - Rebased to latest mainline (and tested again). No functional changes. Changes since v3: - Converted from a single patch to a series. - Tested defconfig builds of all impacted platforms.

[PATCH 0/7] Start deprecating _OSI on new architectures

by al.stone＠linaro.org

From: Al Stone <al.stone(a)linaro.org> The use of the ACPI _OSI method in Linux has a long and sordid history. Instead of perpetuating past complications on new architectures, the consensus amongst those writing the ACPI specification and those using it seems to be to ultimately deprecate the use of _OSI. I plan to propose such a change to the ACPI specification in the near future. In the meantime, these patches rearrange the implementation of _OSI so that it can be deprecated, or ultimately removed completely, on at least arm64 platforms. This is done by simply moving the functions implementing _OSI to arch-dependent locations. For x86, there should be no change in functionality. For ia64, while it does duplicate some code from x86, there is no longer any connection to the ACPI blacklist code that is only used by x86. For arm64, any use of the _OSI method generates a warning that it has been deprecated, and then always returns false; i.e., that the capability being queried for, whether OS name or functionality, is not supported. This is the first six of the patches. The final patch changes the default value for the _OS_ method for arm64 only. Since there is no need to pretend to be older versions of Windows, or any other OS at all, the _OS_ method will return "Linux" on arm64. One can still use the acpi_os_name kernel parameter if there is a need to use some other value. Since we are breaking apart code previously shared, I have tried to make it so that applying the x86 patches alone will continue to compile, at the expense of breaking the build on non-x86 platforms. However, once all of the patches are applied, we should be able to compile on all three architectures. It is best to treat these as one whole. I have only done simple testing with these patches on arm64 and x86 (AMD Seattle and a Lenovo t440s ThinkPad, respectively). Things seem to work as they should once booted, but this is a very, very small sample of possible machines. The ia64 patches cross-compile, but I personally have no way to test them. The arm64 patches also rely on having applied Hanjun's patches for ACPI 5.1 on arm64 [0]. The x86 and ia64 parts are not dependent on that patch set, though, and should be usable independently (i.e., patches 1, 3, 4 and 6). NB: some of the patches do not pass checkpatch.pl; the failures I saw were all part of the original code but are only showing up because that code is changing location, so I have left them as is. If necessary, they could be fixed but I was more concerned about the number of changes needed on ia64 and not having any way to test them.

[RFC] dma-buf: cleanup dma_buf_export() to make it easily extensible

by Sumit Semwal

At present, dma_buf_export() takes a series of parameters, which makes it difficult to add any new parameters for exporters, if required. Make it simpler by moving all these parameters into a struct, and pass the struct * as parameter to dma_buf_export(). While at it, unite dma_buf_export_named() with dma_buf_export(), and change all callers accordingly.

[PATCH v3] ARM: dts: exynos5422-odroidxu3: add on-board INA231 sensors

by Kevin Hilman

From: Kevin Hilman <khilman(a)linaro.org> The odroid-xu3 has 4 INA231 current sensors on board which can be accessed from the Linux via the hwmon interface. There is one sensor for each of these power rails: - A15 cluster: VDD_ARM - A7 cluster: VDD_KFC - GPU: VDD_G3D - memory: VDD_MEM In addition to adding the sensors, LDO26 from the PMIC needs to be enabled because it's powering these sensor.
