50 MHz is an incredibly common clock rate for SD cards to run at.
It's "high speed" mode in SD (not very fast these days, but it used to
be) or:
#define HIGH_SPEED_MAX_DTR 50000000
If we don't support this then older "high speed" cards can only run at
25 MHz or at half their normal speed. There doesn't seem to be any
reason to skip this clock rate, so add it.

I would repeat the same commit message that was in commit 5e4b7e82d4
("clk: qcom: gcc-sdm845: Use floor ops for sdcc clks") but it seems
silly to do so when you could just go read that commit.
NOTE: this is actually extra terrible because we're missing the 50 MHz
rate in the table (see the next patch AKA ("clk: qcom: gcc-sc7180: Add
50 MHz clock rate for SDC2")). That means then when you run an older
SD card it'll try to clock it at 100 MHz when it's only specced to run
at 50 MHz max. As you can probably guess that doesn't work super
well.

Let's call pm_runtime_get() here instead of calling the PM clk APIs

intent, i.e. enable the clks for this device so we can program PLL

The sc7180 lpass clock driver manages two different devices. These
two devices were tangled together, using one probe and a lookup to
figure out the real probe. I think it's cleaner to really separate
the probe for these two devices since they're really different things,
just both managed by the same driver.

Merge tag 'safesetid-5.10' of git://github.com/micah-morton/linux
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
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
(f227e3ec3b) 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.
The whole discussion around this is archived here:

Commit 21653a4181 ("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.
