The baseboard of the Logic PD i.MX6 development kit has a power button routed which can both power down and power up the board. It can also wake the board from sleep. This functionality was marked as disabled by default in imx6qdl.dtsi, so it needs to be explicitly enabled for each board. This patch enables the snvs power key again.

2019-10-09ARM: dts: Use level interrupt for omap4 & 5 wlcoreTony Lindgren
Commit 572cf7d7b07d ("ARM: dts: Improve omap l4per idling with wlcore edge sensitive interrupt") changed wlcore interrupts to use edge interrupt based on what's specified in the wl1835mod.pdf data sheet. However, there are still cases where we can have lost interrupts as described in omap_gpio_unidle(). And using a level interrupt instead of edge interrupt helps as we avoid the check for untriggered GPIO interrupts in omap_gpio_unidle(). And with commit e6818d29ea15 ("gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup") GPIOs idle just fine with level interrupts.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes Fixes for omaps for v5.4-rc cycle Here are fixes for omaps to deal with few regressions, and to fix more boot time errors and warnings: - The recent ti-sysc interconnect target module driver changes had incorrect clock bits for both clocks and dts that cause warnings - For omap3-gta04, gpio changes caused the LCD to break a while back, and after discussing things the right fix is to set spi-cs-high - Recent omapdrm changes to use generic panels caused tfp410 to be disabled as we now must enable the generic support for it in defconfig - Recent omapdrm and backlight changes also finally made droid4 LCD to work, so let's enable it in the defconfig it can be used out of the box. This is not strictly a fix, but we still also have the older CONFIG_MFD_TI_LMU options available so this cuts down the confusion for trying to guess which display and which backlight is needed - Recent ti-sysc interconnect target module changes need the gpio module disabled on some boards, but this now needs to happen at the module level, not at the gpio driver level - Recent changes to probe system timers with ti-sysc caused warnings about mismatch in syconfig registers, so let's configure the option for RESET_STATUS as available in the TRMs - Recent changes to probe LCDC with ti-sysc caused warnings about mismatch in sysconfig registers, so let's configure the missing idlemodes for both platform data and dts as documented in TRMs - Since we moved mach-omap2 to probe with device tree, we've been getting voltage controller warnings.

2019-09-26mm: treewide: clarify pgtable_page_{ctor,dtor}() namingMark Rutland
The naming of pgtable_page_{ctor,dtor}() seems to have confused a few people, and until recently arm64 used these erroneously/pointlessly for other levels of page table. To make it incredibly clear that these only apply to the PTE level, and to align with the naming of pgtable_pmd_page_{ctor,dtor}(), let's rename them to pgtable_pte_page_{ctor,dtor}(). These changes were generated with the following shell script: ---- git grep -lw 'pgtable_page_.tor' | while read FILE; do sed -i '{s/pgtable_page_ctor/pgtable_pte_page_ctor/}' $FILE; sed -i '{s/pgtable_page_dtor/pgtable_pte_page_dtor/}' $FILE; done ---- ... with the documentation re-flowed to remain under 80 columns, and whitespace fixed up in macros to keep backslashes aligned. There should be no functional change as a result of this patch.

2019-09-25ARM: OMAP2+: Add missing LCDC midlemode for am335xTony Lindgren
TRM "Table 13-34. SYSCONFIG Register Field Descriptions" lists both standbymode and idlemode that should be just the sidle and midle registers where midle is currently unconfigured for lcdc_sysc. As the dts data has been generated based on lcdc_sysc, we now have an empty "ti,sysc-midle" property. And so we currently get a warning for lcdc because of a difference with dts provided configuration compared to the legacy platform data. This is because lcdc has SYSC_HAS_MIDLEMODE configured in the platform data without configuring the modes. Let's fix the issue by adding the missing midlemode to lcdc_sysc, and configuring the "ti,sysc-midle" property based on the TRM values.

2019-09-25ARM: OMAP2+: Fix missing reset done flag for am3 and am43Tony Lindgren
For ti,sysc-omap4 compatible devices with no sysstatus register, we do have reset done status available in the SOFTRESET bit that clears when the reset is done. This is documented for example in am437x TRM for DMTIMER_TIOCP_CFG register. The am335x TRM just says that SOFTRESET bit value 1 means reset is ongoing, but it behaves the same way clearing after reset is done. With the ti-sysc driver handling this automatically based on no sysstatus register defined, we see warnings if SYSC_HAS_RESET_STATUS is missing in the legacy platform data: ti-sysc 48042000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48044000.target-module: sysc_flags 00000222 != 00000022 ti-sysc 48046000.target-module: sysc_flags 00000222 != 00000022 ... Let's fix these warnings by adding SYSC_HAS_RESET_STATUS. Let's also remove the useless parentheses while at it. If it turns out we do have ti,sysc-omap4 compatible devices without a working SOFTRESET bit we can set up additional quirk handling for it. Signed-off-by: Tony Lindgren <tony@atomide.com>

2019-09-24arm: use generic mmap top-down layout and brk randomizationAlexandre Ghiti
arm uses a top-down mmap layout by default that exactly fits the generic functions, so get rid of arch specific code and use the generic version by selecting ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT. As ARCH_WANT_DEFAULT_TOPDOWN_MMAP_LAYOUT selects ARCH_HAS_ELF_RANDOMIZE, use the generic version of arch_randomize_brk since it also fits. Note that this commit also removes the possibility for arm to have elf randomization and no MMU: without MMU, the security added by randomization is worth nothing. Note that it is safe to remove STACK_RND_MASK since it matches the default value.

2019-09-24mm: consolidate pgtable_cache_init() and pgd_cache_init()Mike Rapoport
Both pgtable_cache_init() and pgd_cache_init() are used to initialize kmem cache for page table allocations on several architectures that do not use PAGE_SIZE tables for one or more levels of the page table hierarchy. Most architectures do not implement these functions and use __weak default NOP implementation of pgd_cache_init(). Since there is no such default for pgtable_cache_init(), its empty stub is duplicated among most architectures. Rename the definitions of pgd_cache_init() to pgtable_cache_init() and drop empty stubs of pgtable_cache_init().

2019-09-24mm: remove quicklist page table cachesNicholas Piggin
Patch series "mm: remove quicklist page table caches". A while ago Nicholas proposed to remove quicklist page table caches [1]. I've rebased his patch on the curren upstream and switched ia64 and sh to use generic versions of PTE allocation. [1] https://lore.kernel.org/linux-mm/20190711030339.20892-1-npiggin@gmail.com This patch (of 3): Remove page table allocator "quicklists". These have been around for a long time, but have not got much traction in the last decade and are only used on ia64 and sh architectures. The numbers in the initial commit look interesting but probably don't apply anymore. If anybody wants to resurrect this it's in the git history, but it's unhelpful to have this code and divergent allocator behaviour for minor archs. Also it might be better to instead make more general improvements to page allocator if this is still so slow.
