2015-12-26of: Make device nodes kobjects so they show up in sysfsGrant Likely
Device tree nodes are already treated as objects, and we already want to expose them to userspace which is done using the /proc filesystem today. Right now the kernel has to do a lot of work to keep the /proc view in sync with the in-kernel representation. If device_nodes are switched to be kobjects then the device tree code can be a whole lot simpler. It also turns out that switching to using /sysfs from /proc results in smaller code and data size, and the userspace ABI won't change if /proc/device-tree symlinks to /sys/firmware/devicetree/base. v7: Add missing sysfs_bin_attr_init() v6: Add __of_add_property() early init fixes from Pantelis v5: Rename firmware/ofw to firmware/devicetree Fix updating property values in sysfs v4: Fixed build error on Powerpc Fixed handling of dynamic nodes on powerpc v3: Fixed handling of duplicate attribute and child node names v2: switch to using sysfs bin_attributes which solve the problem of reporting incorrect property size.

2015-12-26leds: leds-gpio: Convert gpio_blink_set() to use GPIO descriptorsMika Westerberg
Commit 21f2aae91e902aad ("leds: leds-gpio: Add support for GPIO descriptors") already converted most of the driver to use GPIO descriptors. What is still missing is the platform specific hook gpio_blink_set() and board files which pass legacy GPIO numbers to this driver in platform data. In this patch we handle the former and convert gpio_blink_set() to take GPIO descriptor instead. In order to do this we convert the existing four users to accept GPIO descriptor and translate it to legacy GPIO number in the platform code. This effectively "pushes" legacy GPIO number usage from the driver to platforms. Also add comment to the remaining block describing that it is legacy code path and we are getting rid of it eventually.

2015-12-26ACPICA: Linux: Add support to exclude <asm/acenv.h> inclusion.Lv Zheng

2015-12-26ACPICA: Linux headers: Add <asm/acenv.h> to remove mis-ordered inclusion of ↵Lv Zheng
<asm/acpi.h> There is a mis-order inclusion for <asm/acpi.h>. As we will enforce including <linux/acpi.h> for all Linux ACPI users, we can find the inclusion order is as follows: <linux/acpi.h> <acpi/acpi.h> <acpi/platform/acenv.h> (acenv.h before including aclinux.h) <acpi/platform/aclinux.h> ........................................................................... (aclinux.h before including asm/acpi.h) <asm/acpi.h> @Redundant@ (ACPICA specific stuff) ........................................................................... ........................................................................... (Linux ACPI specific stuff) ? - - - - - - - - - - - - + (aclinux.h after including asm/acpi.h) @Invisible@ | (acenv.h after including aclinux.h) @Invisible@ | other ACPICA headers @Invisible@ | ............................................................|.............. <acpi/acpi_bus.h> | <acpi/acpi_drivers.h> | <asm/acpi.h> (Excluded) | (Linux ACPI specific stuff) ! <- - - - - - - - - - - - - + NOTE that, in ACPICA, <acpi/platform/acenv.h> is more like Kconfig generated <generated/autoconf.h> for Linux, it is meant to be included before including any ACPICA code. In the above figure, there is a question mark for "Linux ACPI specific stuff" in <asm/acpi.h> which should be included after including all other ACPICA header files. Thus they really need to be moved to the position marked with exclaimation mark or the definitions in the blocks marked with "@Invisible@" will be invisible to such architecture specific "Linux ACPI specific stuff" header blocks. This leaves 2 issues: 1. All environmental definitions in these blocks should have a copy in the area marked with "@Redundant@" if they are required by the "Linux ACPI specific stuff". 2. We cannot use any ACPICA defined types in <asm/acpi.h>. This patch splits architecture specific ACPICA stuff from <asm/acpi.h> to fix this issue.
