2020-12-07arm64: dts: meson: fix PHY deassert timing requirementsStefan Agner
According to the datasheet (Rev. 1.9) the RTL8211F requires at least 72ms "for internal circuits settling time" before accessing the PHY registers. This fixes an issue seen on ODROID-C2 where the Ethernet link doesn't come up when using ip link set down/up: [ 6630.714855] meson8b-dwmac c9410000.ethernet eth0: Link is Down [ 6630.785775] meson8b-dwmac c9410000.ethernet eth0: PHY [stmmac-0:00] driver [RTL8211F Gigabit Ethernet] (irq=36) [ 6630.893071] meson8b-dwmac c9410000.ethernet: Failed to reset the dma [ 6630.893800] meson8b-dwmac c9410000.ethernet eth0: stmmac_hw_setup: DMA engine initialization failed [ 6630.902835] meson8b-dwmac c9410000.ethernet eth0: stmmac_open: Hw setup failed Fixes: f29cabf240ed ("arm64: dts: meson: use the generic Ethernet PHY reset GPIO bindings") Reviewed-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Stefan Agner <stefan@agner.ch> Signed-off-by: Kevin Hilman <khilman@baylibre.com> Link: https://lore.kernel.org/r/4a322c198b86e4c8b3dda015560a683babea4d63.1607363522.git.stefan@agner.ch

2020-11-30arm64: dts: meson: Add capacity-dmips-mhz attributes to GXMChristian Hewitt
GXM (S912) is a big-little design with CPUs 0-3 clocked at 1.5GHz and CPUs 4-7 at 1.0GHz. Adding capacity-dmips-mhz attributes allows the scheduler to factor the different clock speeds into capacity calculations and prefer the higher-clocked cluster to improve overall performance. This was inspired by the similar change for G12B [0] boards. The diference here is that all cores are A53's so the same dmips-mhz value is used.

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux Pull more parisc updates from Helge Deller: - During this merge window O_NONBLOCK was changed to become 000200000, but we missed that the syscalls timerfd_create(), signalfd4(), eventfd2(), pipe2(), inotify_init1() and userfaultfd() do a strict bit-wise check of the flags parameter. To provide backward compatibility with existing userspace we introduce parisc specific wrappers for those syscalls which filter out the old O_NONBLOCK value and replaces it with the new one. - Prevent HIL bus driver to get stuck when keyboard or mouse isn't attached - Improve error return codes when setting rtc time - Minor documentation fix in pata_ns87415.c * 'parisc-5.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: ata: pata_ns87415.c: Document support on parisc with superio chip parisc: Add wrapper syscalls to fix O_NONBLOCK flag usage hil/parisc: Disable HIL driver when it gets stuck parisc: Improve error return codes when setting rtc time

Pull SafeSetID updates from Micah Morton: "The changes are mostly contained to within the SafeSetID LSM, with the exception of a few 1-line changes to change some ns_capable() calls to ns_capable_setid() -- causing a flag (CAP_OPT_INSETID) to be set that is examined by SafeSetID code and nothing else in the kernel.

git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom Pull random32 updates from Willy Tarreau: "Make prandom_u32() less predictable. This is the cleanup of the latest series of prandom_u32 experimentations consisting in using SipHash instead of Tausworthe to produce the randoms used by the network stack. The changes to the files were kept minimal, and the controversial commit that used to take noise from the fast_pool (f227e3ec3b5c) was reverted. Instead, a dedicated "net_rand_noise" per_cpu variable is fed from various sources of activities (networking, scheduling) to perturb the SipHash state using fast, non-trivially predictable data, instead of keeping it fully deterministic. The goal is essentially to make any occasional memory leakage or brute-force attempt useless. The resulting code was verified to be very slightly faster on x86_64 than what is was with the controversial commit above, though this remains barely above measurement noise. It was also tested on i386 and arm, and build- tested only on arm64" Link: https://lore.kernel.org/netdev/20200808152628.GA27941@SDF.ORG/ * tag '20201024-v4-5.10' of git://git.kernel.org/pub/scm/linux/kernel/git/wtarreau/prandom: random32: add a selftest for the prandom32 code random32: add noise from network and scheduling activity random32: make prandom_u32() output unpredictable
2020-10-25i2c: core: Restore acpi_walk_dep_device_list() getting called after ↵Hans de Goede
registering the ACPI i2c devs Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")'s intention was to only move the acpi_install_address_space_handler() call to the point before where the ACPI declared i2c-children of the adapter where instantiated by i2c_acpi_register_devices(). But i2c_acpi_install_space_handler() had a call to acpi_walk_dep_device_list() hidden (that is I missed it) at the end of it, so as an unwanted side-effect now acpi_walk_dep_device_list() was also being called before i2c_acpi_register_devices(). Move the acpi_walk_dep_device_list() call to the end of i2c_acpi_register_devices(), so that it is once again called *after* the i2c_client-s hanging of the adapter have been created. This fixes the Microsoft Surface Go 2 hanging at boot.
