2016-04-27ARM: dts: imx6: Do not hardcode the CLKO clockFabio Estevam

2016-04-27ARM: dts: imx6: Add dts for Embest MarS BoardSergio Prado

2016-04-26ARM: dts: imx6: fix dtc warnings for ipu endpointsJoshua Clayton
When compiled with "W=1", dtc complains: e.g. "Warning (unit_address_vs_reg): Node /soc/ipu@02800000/port@2/endpoint@0 has a unit name, but no reg property" Endpoint nodes don't have a reg property, and the addresses in their node names are ordinals without any special meaning so remove them and swap them for semantic node names.

2016-04-26ARM: dts: imx6dl: Fix the VDD_ARM_CAP voltage for 396MHz operationFabio Estevam
Table 8 from MX6DL datasheet (IMX6SDLCEC Rev. 5, 06/2015): http://cache.nxp.com/files/32bit/doc/data_sheet/IMX6SDLCEC.pdf states the following: "LDO Output Set Point (VDD_ARM_CAP) = 1.125 V minimum for operation up to 396 MHz." So fix the entry by adding the 25mV margin value as done in the other entries of the table, which results in 1.15V for 396MHz operation.

2016-04-26ARM: dts: imx6q-b850v3: Update display clock sourceAkshay Bhat
The default monitor that ships with B850v3 requires a 65MHz pixel clock. 65MHz can not be achieved using PLL3 (480MHz/7=68.5MHz). Hence set the LDB_DIx clock source to PLL5. Since PLL5 is already in use by IPU1_DIx, set the clock source for IPU1_DIx to PLL2_PFD2 to allow simultaneous display on both LVDS and HDMI interface.

2016-04-26ARM: dts: imx6q-b850v3: Remove ldb panelAkshay Bhat
Remove ldb panel entry for the following reasons: - The b850v3 has an onboard LVDS to DisplayPort converter (STDP4028). So we should not limit the monitors that can be connected by hardcoding the auo,b133htn01 1080p panel. - The default resolution on the LVDS interface needs to be WXGA or less. Otherwise when a 1080p monitor is connected to the HDMI port there is no output on both the LVDS and HDMI ports since a single IPU on i.MX6 can not handle two 1080p displays. With the panel entry removed from the devicetree, drm driver defaults the resolution on LVDS interface to XGA. Once in userspace, applications can set the desired resolution on LVDS interface over IPU2 CRTC. Signed-off-by: Akshay Bhat <akshay.bhat@timesys.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>

The official UDOO board kit has 7 and 15.6 inch touchscreen LCD panels as options. This patch adds support for 7 inch panel only, but the 15.6 inch one should be easy to add using the same regulator, backlight device and LVDS channel. Since this panel is an option for UDOO board it is disabled by default and can be enabled (for example) by the following U-Boot commands: fdt set backlight status okay fdt set panelchan status okay fdt set panel7 status okay fdt set touchscreenp7 status okay The LVDS channels is also disabled by default to avoid warning from its driver.

2016-03-25mm, kasan: stackdepot implementation. Enable stackdepot for SLABAlexander Potapenko
Implement the stack depot and provide CONFIG_STACKDEPOT. Stack depot will allow KASAN store allocation/deallocation stack traces for memory chunks. The stack traces are stored in a hash table and referenced by handles which reside in the kasan_alloc_meta and kasan_free_meta structures in the allocated memory chunks. IRQ stack traces are cut below the IRQ entry point to avoid unnecessary duplication. Right now stackdepot support is only enabled in SLAB allocator. Once KASAN features in SLAB are on par with those in SLUB we can switch SLUB to stackdepot as well, thus removing the dependency on SLUB stack bookkeeping, which wastes a lot of memory. This patch is based on the "mm: kasan: stack depots" patch originally prepared by Dmitry Chernenkov. Joonsoo has said that he plans to reuse the stackdepot code for the mm/page_owner.c debugging facility.

2016-03-25arch, ftrace: for KASAN put hard/soft IRQ entries into separate sectionsAlexander Potapenko
KASAN needs to know whether the allocation happens in an IRQ handler. This lets us strip everything below the IRQ entry point to reduce the number of unique stack traces needed to be stored. Move the definition of __irq_entry to <linux/interrupt.h> so that the users don't need to pull in <linux/ftrace.h>. Also introduce the __softirq_entry macro which is similar to __irq_entry, but puts the corresponding functions to the .softirqentry.text section.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "There are only three patches this time, most other changes to files in include/asm-generic tend to go through the tree of whoever depends on the change. Two patches are cleanups for stuff that is no longer needed, the main change is to adapt the generic version of BUG_ON() for CONFIG_BUG=n to make it behave consistently with BUG(). This avoids undefined behavior along with a number of warnings about that undefined behavior in randconfig builds when we keep going on after hitting a BUG_ON()" * tag 'asm-generic-4.6' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: asm-generic: remove old nonatomic-io wrapper files asm-generic: default BUG_ON(x) to if(x)BUG() asm-generic: page.h: Remove useless get_user_page and free_user_page
