Annotate the external MDIO1 node and describe the 8 QSGMII PHYs found on the LS1088ARDB board and add phy-handles for DPMACs 3-10 to its associated PHY. Also, add the internal PCS MDIO nodes for the internal MDIO buses found on the LS1088A SoC along with their internal PCS PHY and link the corresponding DPMAC to the PCS through the pcs-handle. Also, rename the dpmac@x nodes to ethernet@x in order to be compliant with the naming convention used by ethernet controllers.

In accordance with the DWC USB3 bindings the corresponding node name is suppose to comply with the Generic USB HCD DT schema, which requires the USB nodes to have the name acceptable by the regexp: "^usb(@.*)?" . Make sure the "snps,dwc3"-compatible nodes are correctly named.

Different revision of i.MX8MP EVK boards may have different external pull up registor design, some are enabled while some are NOT, to make sure the WDOG_B pin works properly, better to enable internal pull up resistor. Since enabling internal pull up resistor is NOT harmful and having benefit of flexibility on different board design, just enable it for all i.MX8MP boards; And schmitt input is NOT necessary for this WDOG_B output pin, so remove it; Open drain outputs provide more flexibility to a designer as they can be pulled-up to any voltage found in the system, so enable it as well.

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 (f227e3ec) 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

Commit 21653a41 ("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.
