git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media Pull media updates from Mauro Carvalho Chehab: - Media documentation is now split into admin-guide, driver-api and userspace-api books (a longstanding request from Jon); - The media Kconfig was reorganized, in order to make easier to select drivers and their dependencies; - The testing drivers now has a separate directory; - added a new driver for Rockchip Video Decoder IP; - The atomisp staging driver was resurrected. It is meant to work with 4 generations of cameras on Atom-based laptops, tablets and cell phones. So, it seems worth investing time to cleanup this driver and making it in good shape. - Added some V4L2 core ancillary routines to help with h264 codecs; - Added an ov2740 image sensor driver; - The si2157 gained support for Analog TV, which, in turn, added support for some cx231xx and cx23885 boards to also support analog standards; - Added some V4L2 controls (V4L2_CID_CAMERA_ORIENTATION and V4L2_CID_CAMERA_SENSOR_ROTATION) to help identifying where the camera is located at the device; - VIDIOC_ENUM_FMT was extended to support MC-centric devices; - Lots of drivers improvements and cleanups. * tag 'media/v5.8-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (503 commits) media: Documentation: media: Refer to mbus format documentation from CSI-2 docs media: s5k5baf: Replace zero-length array with flexible-array media: i2c: imx219: Drop <linux/clk-provider.h> and <linux/clkdev.h> media: i2c: Add ov2740 image sensor driver media: ov8856: Implement sensor module revision identification media: ov8856: Add devicetree support media: dt-bindings: ov8856: Document YAML bindings media: dvb-usb: Add Cinergy S2 PCIe Dual Port support media: dvbdev: Fix tuner->demod media controller link media: dt-bindings: phy: phy-rockchip-dphy-rx0: move rockchip dphy rx0 bindings out of staging media: staging: dt-bindings: phy-rockchip-dphy-rx0: remove non-used reg property media: atomisp: unify the version for isp2401 a0 and b0 versions media: atomisp: update TODO with the current data media: atomisp: adjust some code at sh_css that could be broken media: atomisp: don't produce errs for ignored IRQs media: atomisp: print IRQ when debugging media: atomisp: isp_mmu: don't use kmem_cache media: atomisp: add a notice about possible leak resources media: atomisp: disable the dynamic and reserved pools media: atomisp: turn on camera before setting it ...

2020-06-03mm/thp: rename pmd_mknotpresent() as pmd_mkinvalid()Anshuman Khandual
pmd_present() is expected to test positive after pmdp_mknotpresent() as the PMD entry still points to a valid huge page in memory. pmdp_mknotpresent() implies that given PMD entry is just invalidated from MMU perspective while still holding on to pmd_page() referred valid huge page thus also clearing pmd_present() test. This creates the following situation which is counter intuitive. [pmd_present(pmd_mknotpresent(pmd)) = true] This renames pmd_mknotpresent() as pmd_mkinvalid() reflecting the helper's functionality more accurately while changing the above mentioned situation as follows. This does not create any functional change. [pmd_present(pmd_mkinvalid(pmd)) = true] This is not applicable for platforms that define own pmdp_invalidate() via __HAVE_ARCH_PMDP_INVALIDATE. Suggestion for renaming came during a previous discussion here. https://patchwork.kernel.org/patch/11019637/ [anshuman.khandual@arm.com: change pmd_mknotvalid() to pmd_mkinvalid() per Will] Link: http://lkml.kernel.org/r/1587520326-10099-3-git-send-email-anshuman.khandual@arm.com Suggested-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Anshuman Khandual <anshuman.khandual@arm.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Acked-by: Will Deacon <will@kernel.org> Cc: Vineet Gupta <vgupta@synopsys.com> Cc: Russell King <linux@armlinux.org.uk> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Ingo Molnar <mingo@redhat.com> Cc: Borislav Petkov <bp@alien8.de> Cc: "H.

2020-06-03arm: simplify detection of memory zone boundariesMike Rapoport
free_area_init() only requires the definition of maximal PFN for each of the supported zone rater than calculation of actual zone sizes and the sizes of the holes between the zones. After removal of CONFIG_HAVE_MEMBLOCK_NODE_MAP the free_area_init() is available to all architectures. Using this function instead of free_area_init_node() simplifies the zone detection.

2020-05-28ARM: OMAP2+: Fix regression for using local timer on non-SMP SoCsTony Lindgren
On am437x we use also an ARM timer in addition to the dmtimer. As am437x is not an SMP SoC, we need tick_broadcast() implemented. With the recent dmtimer changes, Arnd started to see link failures for non-SMP am437x configuration: kernel/time/tick-broadcast.o: in function `tick_device_uses_broadcast': tick-broadcast.c:(.text+0x130): undefined reference to `tick_broadcast' Let's fix the issue by reverting dmtimer related changes that started building timer.c only for CONFIG_SOC_HAS_REALTIME_COUNTER. We still always need timer.c built-in for omap5 and dra7 for timer_probe(). And let's also move am437x tick_broadcast() to board-generic.c as that's where we now call timer_probe() for am437x. This way we avoid adding back more ifdefs to timer.c.

Apart from the clocks and resets, the PMU hardware also controls power to peripherals that are on separate power islands. On MMP2, that's the GC860 GPU and the SSPA audio interface, while on MMP3 also the camera interface is on a separate island, along with the pair of GC2000 and GC300 GPUs and the SSPA.

2020-05-26ARM: 8980/1: Allow either FLATMEM or SPARSEMEM on the multiplatform buildGregory Fong
ARMv7 chips with LPAE can often benefit from SPARSEMEM, as portions of system memory can be located deep in the 36-bit address space. Allow FLATMEM or SPARSEMEM to be selectable at compile time; FLATMEM remains the default. This is based on Kevin's "[PATCH 3/3] ARM: Allow either FLATMEM or SPARSEMEM on the multi-v7 build" from [1] and shamelessly rips off his commit message text above. As Arnd pointed out at [2] there doesn't seem to be any reason to tie this specifically to ARMv7, so this has been changed to apply to all multiplatform kernels. The addition of this option does not change the defaults and a build with any defconfig will behave the same way as previously. The only effect this change has is to enable user to change "Memory model" selection in interactive kernel configuration (menuconfig, xconfig etc).

2020-05-26ARM: 8979/1: Remove redundant ARCH_SPARSEMEM_DEFAULT settingKevin Cernekee
If ARCH_SPARSEMEM_ENABLE=y and ARCH_{FLATMEM,DISCONTIGMEM}_ENABLE=n, then the logic in mm/Kconfig already makes CONFIG_SPARSEMEM the only choice. This is true for all of the existing ARM users of ARCH_SPARSEMEM_ENABLE. Forcing ARCH_SPARSEMEM_DEFAULT=y if ARCH_SPARSEMEM_ENABLE=y prevents us from ever defaulting to FLATMEM, so we should remove this setting.

2020-05-26ARM: 8978/1: mm: make act_mm() respect THREAD_SIZELinus Walleij
Recent work with KASan exposed the folling hard-coded bitmask in arch/arm/mm/proc-macros.S: bic rd, sp, #8128 bic rd, rd, #63 This forms the bitmask 0x1FFF that is coinciding with (PAGE_SIZE << THREAD_SIZE_ORDER) - 1, this code was assuming that THREAD_SIZE is always 8K (8192). As KASan was increasing THREAD_SIZE_ORDER to 2, I ran into this bug. Fix it by this little oneline suggested by Ard: bic rd, sp, #(THREAD_SIZE - 1) & ~63 Where THREAD_SIZE is defined using THREAD_SIZE_ORDER. We have to also include <linux/const.h> since the THREAD_SIZE expands to use the _AC() macro.

git://git.kernel.org/pub/scm/linux/kernel/git/ardb/linux into misc Simplify EFI handover to decompressor The EFI stub in the ARM kernel runs in the context of the firmware, which means it usually runs with the caches and MMU on. Currently, we relocate the zImage so it appears in the first 128 MiB, disable the MMU and caches and invoke the decompressor via its ordinary entry point. However, since we can pass the base of DRAM directly, there is no need to relocate the zImage, which also means there is no need to disable and re-enable the caches and create new page tables etc. This also allows systems whose DRAM start address is not a round multiple of 128 MB to decompress the kernel proper to the base of memory, ensuring that all memory is usable at runtime.
