Document new OPP table and voltage regulator properties which are needed for supporting dynamic voltage-frequency scaling of the memory controller. Some boards may have a fixed core voltage regulator, hence it's optional because frequency scaling still may be desired.

Tegra20 External Memory Controller talks to DRAM chips and it needs to be reprogrammed when memory frequency changes. Tegra Memory Controller sits behind EMC and these controllers are tightly coupled. This patch adds the new phandle property which allows to properly express connection of EMC and MC hardware in a device-tree, it also put the Tegra20 EMC binding on par with Tegra30+ EMC bindings, which is handy to have.

2020-10-29clk: samsung: exynos-clkout: convert to module driverKrzysztof Kozlowski1-57/+141
The Exynos clkout driver depends on board input clock (typically XXTI or XUSBXTI), however on Exynos4 boards these clocks were modeled as part of SoC clocks (Exynos4 clocks driver). Obviously this is not proper, but correcting it would break DT backward compatibility. Both drivers - clkout and Exynos4 clocks - register the clock providers with CLK_OF_DECLARE/OF_DECLARE_1 so their order is fragile (in the Makefile clkout is behind Exynos4 clock). It will work only if the Exynos4 clock driver comes up before clkout. A change in DTS adding input clock reference to Exynos4 clocks input PLL, see reverted commit eaf2d2f6895d ("ARM: dts: exynos: add input clock to CMU in Exynos4412 Odroid"), caused probe reorder: the clkout appeared before Exynos4 clock provider. Since clkout depends on Exynos4 clocks and does not support deferred probe, this did not work and caused later failure of usb3503 USB hub probe which needs clkout: [ 5.007442] usb3503 0-0008: unable to request refclk (-517) The Exynos clkout driver is not a critical/core clock so there is actually no problem in instantiating it later, as a regular module. This removes specific probe ordering and adds support for probe deferral.

2020-10-29soc: samsung: exynos-pmu: instantiate clkout driver as MFDKrzysztof Kozlowski1-0/+11
The Exynos clock output (clkout) driver uses same register address space (Power Management Unit address space) as Exynos PMU driver and same set of compatibles. It was modeled as clock provider instantiated with CLK_OF_DECLARE_DRIVER(). This however brings ordering problems and lack of probe deferral, therefore clkout driver should be converted to a regular module and instantiated as a child of PMU driver to be able to use existing compatibles and address space.

According to Tegra X1 TRM, there are missing swgroups in the tegra210_swgroups list. So this patch adds them in bindings. Note that the TEGRA_SWGROUP_GPU (in list) should be actually TEGRA_SWGROUP_GPUB (in TRM), yet TEGRA_SWGROUP_GPU (in TRM) is not being used -- only TEGRA_SWGROUP_GPUB (in TRM) is.

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. The changes to SafeSetID internally allow for setting up GID transition security policies, as already existed for UIDs" * tag 'safesetid-5.10' of git://github.com/micah-morton/linux: LSM: SafeSetID: Fix warnings reported by test bot LSM: SafeSetID: Add GID security policy handling LSM: Signal to SafeSetID when setting group IDs

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 Goede1-1/+10
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.
