Revert "clk: Drop the rate range on clk_put()"
This reverts commit
7dabfa2bc4803eed83d6f22bd6f045495f40636b. There are
multiple reports that this breaks boot on various systems. The common
theme is that orphan clks are having rates set on them when that isn't
expected. Let's revert it out for now so that -rc1 boots.

clk: Drop the rate range on clk_put()
When clk_put() is called we don't make another clk_set_rate() call to
re-evaluate the rate boundaries. This is unlike clk_set_rate_range()
that evaluates the rate again each time it is called.
However, clk_put() is essentially equivalent to clk_set_rate_range()
since after clk_put() completes the consumer's boundaries shouldn't be
enforced anymore.
Let's add a call to clk_set_rate_range() in clk_put() to make sure those
rate boundaries are dropped and the clock provider drivers can react.
Also add a few tests to make sure this case is covered.

clk: test: Test clk_set_rate_range on orphan mux
A bug recently affected the Tegra30 where calling clk_set_rate_range()
on a clock would make it change its rate to the minimum.
This was due to the clock in question being a mux that was orphan at
registration, which lead to the clk_core req_rate being 0, and the
clk_set_rate_range() function then calling clk_set_rate() with req_rate,
effectively making that clock running at the minimum rate allowed, even
though the initial rate was within that range.
Make a test suite to create a mux initially orphan, and then make sure
that if our clock rate was initially within a given range, then
enforcing that range won't affect it.

clk: Initialize orphan req_rate
When registering a clock that doesn't have a recalc_rate implementation,
and doesn't have its parent registered yet, we initialize the clk_core
rate and 'req_rate' fields to 0.
The rate field is later updated when the parent is registered in
clk_core_reparent_orphans_nolock() using __clk_recalc_rates(), but the
'req_rate' field is never updated.
This leads to an issue in clk_set_rate_range() and clk_put(), since
those functions will call clk_set_rate() with the content of 'req_rate'
to provide drivers with the opportunity to change the rate based on the
new boundaries. In this case, we would call clk_set_rate() with a rate
of 0, effectively enforcing the minimum allowed for this clock whenever
we would call one of those two functions, even though the actual rate
might be within range.
Let's fix this by setting 'req_rate' in
clk_core_reparent_orphans_nolock() with the rate field content just
updated by the call to __clk_recalc_rates().

The core clock and M2MC clocks are shared between some devices (Unicam
controllers and the HVS, and the HDMI controllers, respectively) that
will have various, varying, requirements depending on their current work
load.
Since those loads can require a fairly high clock rate in extreme
conditions (up to ~600MHz), we can end up running those clocks at their
maximum frequency even though we no longer require such a high rate.
Fortunately, those devices don't require an exact rate but a minimum
rate, and all the drivers are using clk_set_min_rate. Thus, we can just
rely on the fact that the clk_request minimum (which is the aggregated
minimum of all the clock users) is what we want at all times.

When we change a clock minimum or maximum using clk_set_rate_range(),
clk_set_min_rate() or clk_set_max_rate(), the current code will only
trigger a new rate change if the rate is outside of the new boundaries.
However, a clock driver might want to always keep the clock rate to
one of its boundary, for example the minimum to keep the power
consumption as low as possible.
Since they don't always get called though, clock providers don't have the
opportunity to implement this behaviour.
Let's trigger a clk_set_rate() on the previous requested rate every time
clk_set_rate_range() is called. That way, providers that care about the
new boundaries have a chance to adjust the rate, while providers that
don't care about those new boundaries will return the same rate than
before, which will be ignored by clk_set_rate() and won't result in a

clk: Always clamp the rounded rate
The current core while setting the min and max rate properly in the
clk_request structure will not make sure that the requested rate is
within these boundaries, leaving it to each and every driver to make
sure it is.
It's not clear if this was on purpose or not, but this introduces some
inconsistencies within the API.
For example, a user setting a range and then calling clk_round_rate()
with a value outside of that range will get the same value back
(ignoring any driver adjustements), effectively ignoring the range that
was just set.
Another one, arguably worse, is that it also makes clk_round_rate() and
clk_set_rate() behave differently if there's a range and the rate being
used for both is outside that range. As we have seen, the rate will be
returned unchanged by clk_round_rate(), but clk_set_rate() will error
out returning -EINVAL.
Let's make sure the framework will always clamp the rate to the current
range found on the clock, which will fix both these inconsistencies.

clk: Enforce that disjoints limits are invalid
If we were to have two users of the same clock, doing something like:
clk_set_rate_range(user1, 1000, 2000);
clk_set_rate_range(user2, 3000, 4000);
The second call would fail with -EINVAL, preventing from getting in a
situation where we end up with impossible limits.
However, this is never explicitly checked against and enforced, and
works by relying on an undocumented behaviour of clk_set_rate().
Indeed, on the first clk_set_rate_range will make sure the current clock
rate is within the new range, so it will be between 1000 and 2000Hz. On
the second clk_set_rate_range(), it will consider (rightfully), that our
current clock is outside of the 3000-4000Hz range, and will call
clk_core_set_rate_nolock() to set it to 3000Hz.
clk_core_set_rate_nolock() will then call clk_calc_new_rates() that will
eventually check that our rate 3000Hz rate is outside the min 3000Hz max
2000Hz range, will bail out, the error will propagate and we'll
eventually return -EINVAL.
This solely relies on the fact that clk_calc_new_rates(), and in
particular clk_core_determine_round_nolock(), won't modify the new rate
allowing the error to be reported. That assumption won't be true for all
drivers, and most importantly we'll break that assumption in a later
patch.
It can also be argued that we shouldn't even reach the point where we're
calling clk_core_set_rate_nolock().
Let's make an explicit check for disjoints range before we're doing
anything.

clk: Fix clk_hw_get_clk() when dev is NULL
Any registered clk_core structure can have a NULL pointer in its dev
field. While never actually documented, this is evidenced by the wide
usage of clk_register and clk_hw_register with a NULL device pointer,
and the fact that the core of_clk_hw_register() function also passes a
NULL device pointer.
A call to clk_hw_get_clk() on a clk_hw struct whose clk_core is in that
case will result in a NULL pointer derefence when it calls dev_name() on
that NULL device pointer.
Add a test for this case and use NULL as the dev_id if the device
pointer is NULL.

clk: starfive: jh7100: Don't round divisor up twice
The problem is best illustrated by an example. Suppose a consumer wants
a 4MHz clock rate from a divider with a 10MHz parent. It would then
call
clk_round_rate(clk, 4000000)
which would call into our determine_rate() callback that correctly
rounds up and finds that a divisor of 3 gives the highest possible
frequency below the requested 4MHz and returns
10000000 / 3 = 3333333Hz.
However the consumer would then call
clk_set_rate(clk, 3333333)
but since 3333333 doesn't divide
10000000 evenly our set_rate() callback
would again round the divisor up and set it to 4 which results in an
unnecessarily low rate of 2.5MHz.
Fix it by using DIV_ROUND_CLOSEST in the set_rate() callback.

clk: qcom: Fix sorting of SDX_GCC_65 in Makefile and Kconfig
In order to keep at least the list of `CONFIG_SM_` drivers sorted
alphabetically, SDX_GCC_65 should have been moved one line up. This in
turn makes it easier and cleaner to add the followup SM_DISPCC_6125
driver in the right place, right before SM_DISPCC_8250.
