The servers for the @codeaurora domain are long retired and any messages
addressed there will bounce. Govind Singh has left the company which
appears to leave the Q6SSTOP clock controller binding unmaintained.
Move maintenance of the binding to the Qualcomm Clock Drivers maintainer
as suggested by Bjorn Andersson.

When SPI transfer is being prepared, the spi-s3c64xx driver will call
clk_set_rate() to change the rate of SPI source clock (IPCLK). But IPCLK
is a gate (leaf) clock, so it must propagate the rate change up the
clock tree, so that corresponding DIV clocks can actually change their
divider values. Add CLK_SET_RATE_PARENT flag to corresponding clocks for
all SPI instances in Exynos850 (spi_0, spi_1 and spi_2) to make it
possible. This change involves next clocks:
usi_spi_0:
Clock Block Div range
--------------------------------------------
gout_spi0_ipclk CMU_PERI -
dout_peri_spi0 CMU_PERI /1..32
mout_peri_spi_user CMU_PERI -
dout_peri_ip CMU_TOP /1..16
usi_cmgp0:
Clock Block Div range
--------------------------------------------
gout_cmgp_usi0_ipclk CMU_CMGP -
dout_cmgp_usi0 CMU_CMGP /1..32
mout_cmgp_usi0 CMU_CMGP -
gout_clkcmu_cmgp_bus CMU_APM -
dout_apm_bus CMU_APM /1..8
usi_cmgp1:
Clock Block Div range
--------------------------------------------
gout_cmgp_usi1_ipclk CMU_CMGP -
dout_cmgp_usi1 CMU_CMGP /1..32
mout_cmgp_usi1 CMU_CMGP -
gout_clkcmu_cmgp_bus CMU_APM -
dout_apm_bus CMU_APM /1..8
With input clock of 400 MHz, this scheme provides next IPCLK rate range,
for each SPI block:
SPI0: 781 kHz ... 400 MHz
SPI1/2: 1.6 MHz ... 400 MHz
Accounting for internal /4 divider in SPI blocks, and because the max
SPI frequency is limited at 50 MHz, it gives us next SPI SCK rates:
SPI0: 200 kHz ... 49.9 MHz
SPI1/2: 400 kHz ... 49.9 MHz
Which should cover all possible applications of SPI bus. Of course,
setting SPI frequency to values as low as 500 kHz will also affect the
common bus dividers (dout_apm_bus or dout_peri_ip), which in turn
effectively lowers the rates for all leaf bus clocks derived from those
dividers, like HSI2C and I3C clocks. But at least it gives the board
designer a choice, whether to keep all clocks (SPI/HSI2C/I3C) at high
frequencies, or make all those clocks have lower frequencies. Not
propagating the rate change to those common dividers would limit this
choice to "only high frequencies are allowed for SPI/HSI2C/I3C" option,
making the common dividers useless. This decision follows the "Worse is
better" approach, relying on the users/engineers to know the system
internals when working with such low-level features, instead of trying
to account for all possible use-cases.

This pclk clock is required any time we access the pinctrl registers of
this block.
Since pinctrl-samsung doesn't support a clock at the moment, we just
keep the kernel from disabling it at boot, until we have an update for
pinctrl-samsung to handle this required clock, at which point we'll be
able to drop the flag again.

The GX GDSC is modelled to aid the GMU in powering down the GPU in the
event that the GPU crashes, so that it can be restarted again. But in
the event that the power-domain is supplied through a dedicated
regulator (in contrast to being a subdomin of another power-domain),
something needs to turn that regulator on, both to make sure things are
powered and to match the operation in gdsc_disable().

Some boards might use Linux and another OS at the same time. In such
case, currently, during booting, Linux will stop necessary module clocks
which are not used on the Linux side, but are used by another OS.
To avoid such situation, renesas-cpg-mssr tries to find
status = "reserved" devices (A), and adds CLK_IGNORE_UNUSED flag to its
<&cgp CPG_MOD xxx> clock (B).
Table 2.4: Values for status property
https://github.com/devicetree-org/devicetree-specification/releases/download/v0.4/devicetree-specification-v0.4.pdf
"reserved"
Indicates that the device is operational, but should not be
used. Typically this is used for devices that are controlled
by another software component, such as platform firmware.

scif5: serial@e6f30000 {

Linux Kernel has __of_device_is_available() / __of_device_is_fail(),
these are checking if the status was "okay" / "ok" / "fail" / "fail-".
Add more generic __of_device_is_status() function for these.

Update cmu_misc so it is registered early, as it contains
the gate which clocks the Multi Core Timer (MCT). This clock
is required early in boot, otherwise exynos_mct will fail
obtaining the clock.
Note this wasn't previously an issue as exynos_mct wasn't
enabled.

The cmu_misc clock-names were renamed to just "bus" and "sss" because
naming is local to the module, so cmu_misc is implied. As the bindings
and the device tree have not made a release yet, comply with the
renamed clocks.

'bus' and 'ip' are sufficient because naming is local to the module.
As the bindings have not made a release yet, rename the cmu_misc
clock-names.

Pull more bcachefs updates from Kent Overstreet:
"Some fixes, Some refactoring, some minor features:
- Assorted prep work for disk space accounting rewrite
- BTREE_TRIGGER_ATOMIC: after combining our trigger callbacks, this
makes our trigger context more explicit
- A few fixes to avoid excessive transaction restarts on
multithreaded workloads: fstests (in addition to ktest tests) are
now checking slowpath counters, and that's shaking out a few bugs
- Assorted tracepoint improvements
- Starting to break up bcachefs_format.h and move on disk types so
they're with the code they belong to; this will make room to start
documenting the on disk format better.
- A few minor fixes"
