f316cdff8d clk: Annotate struct clk_hw_onecell_data with __counted_by
Prepare for the coming implementation by GCC and Clang of the __counted_by
attribute. Flexible array members annotated with __counted_by can have
their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS
(for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family
functions).

As found with Coccinelle[1], add __counted_by for struct clk_hw_onecell_data.
Additionally, since the element count member must be set before accessing
the annotated flexible array member, move its initialization earlier.

ebf51575c8 clk: fix typo in clk_hw_register_fixed_rate_parent_data() macro
clk_hw_register_fixed_rate_parent_data() 3rd parameter is parent_data
not parent_hw. Inner function (__clk_hw_register_fixed_rate()) is called
with parent_data parameter as valid. To have this parameter taken into
account update the name of the 3rd parameter of
clk_hw_register_fixed_rate_parent_data() macro to parent_data.

33b70fbc4f clk: Introduce clk_hw_determine_rate_no_reparent()
Some clock drivers do not want to allow any reparenting on a given
clock, but usually do so by not providing any determine_rate
implementation.

Whenever we call clk_round_rate() or clk_set_rate(), this leads to
clk_core_can_round() returning false and thus the rest of the function
either forwarding the rate request to its current parent if
CLK_SET_RATE_PARENT is set, or just returning the current clock rate.

This behaviour happens implicitly, and as we move forward to making a
determine_rate implementation required for muxes, we need some way to
explicitly opt-in for that behaviour.

Fortunately, this is exactly what the clk_core_determine_rate_no_reparent()
function is doing, so we can simply make it available to drivers.

Linus Torvalds
e81507acdc Nothing looks out of the ordinary in this batch of clk driver updates. There
are a couple patches to the core clk framework, but they're all basically
 cleanups or debugging aids. The driver updates and new additions are dominated
 in the diffstat by Qualcomm and MediaTek drivers. Qualcomm gained a handful of
 new drivers for various SoCs, and MediaTek gained a bunch of drivers for
 MT8188. The MediaTek drivers are being modernized as well, so there are
 updates all over that vendor's clk drivers. There's also a couple other new clk
 drivers in here, for example the Starfive JH7110 SoC support is added.
 
 Outside of the two major SoC vendors though, we have the usual collection of
 non-critical fixes and cleanups to various clk drivers. It's good to see that
 we're getting more cleanups and modernization patches. Maybe one day we'll be
 able to properly split clk providers from clk consumers.

c28cd1f343 clk: Mark a fwnode as initialized when using CLK_OF_DECLARE() macro
We already mark fwnodes as initialized when they are registered as clock
providers. We do this so that fw_devlink can tell when a clock driver
doesn't use the driver core framework to probe/initialize its device.
This ensures fw_devlink doesn't block the consumers of such a clock
provider indefinitely.

However, some users of CLK_OF_DECLARE() macros don't use the same node
that matches the macro as the node for the clock provider, but they
initialize the entire node. To cover these cases, also mark the nodes
that match the macros as initialized when the init callback function is
called.

An example of this is "stericsson,u8500-clks" that's handled using
CLK_OF_DECLARE() and looks something like this:

clocks {
	compatible = "stericsson,u8500-clks";

	prcmu_clk: prcmu-clock {
		#clock-cells = <1>;
	};

	prcc_pclk: prcc-periph-clock {
		#clock-cells = <2>;
	};

	prcc_kclk: prcc-kernel-clock {
		#clock-cells = <2>;
	};

	prcc_reset: prcc-reset-controller {
		#reset-cells = <2>;
	};
	...
};

This patch makes sure that "clocks" is marked as initialized so that
fw_devlink knows that all nodes under it have been initialized. If the
driver creates struct devices for some of the subnodes, fw_devlink is
smart enough to know to wait for those devices to probe, so no special
handling is required for those cases.

ef13f8b647 clk: Store clk_core for clk_rate_request
The struct clk_rate_request is meant to store the context around a rate
request such as the parent, boundaries, and so on.

However, it doesn't store the clock the rate request is submitted to,
which makes debugging difficult.

Let's add a pointer to the relevant clk_core instance in order to
improve the debugging of rate requests in a subsequent patch.

262ca38f4b clk: Stop forwarding clk_rate_requests to the parent
If the clock cannot modify its rate and has CLK_SET_RATE_PARENT,
clk_mux_determine_rate_flags(), clk_core_round_rate_nolock() and a
number of drivers will forward the clk_rate_request to the parent clock.

clk_core_round_rate_nolock() will pass the pointer directly, which means
that we pass a clk_rate_request to the parent that has the rate,
min_rate and max_rate of the child, and the best_parent_rate and
best_parent_hw fields will be relative to the child as well, so will
point to our current clock and its rate. The most common case for
CLK_SET_RATE_PARENT is that the child and parent clock rates will be
equal, so the rate field isn't a worry, but the other fields are.

Similarly, if the parent clock driver ever modifies the best_parent_rate
or best_parent_hw, this will be applied to the child once the call to
clk_core_round_rate_nolock() is done. best_parent_hw is probably not
going to be a valid parent, and best_parent_rate might lead to a parent
rate change different to the one that was initially computed.

clk_mux_determine_rate_flags() and the affected drivers will copy the
request before forwarding it to the parents, so they won't be affected
by the latter issue, but the former is still going to be there and will
lead to erroneous data and context being passed to the various clock
drivers in the same sub-tree.

Let's create two new functions, clk_core_forward_rate_req() and
clk_hw_forward_rate_request() for the framework and the clock providers
that will copy a request from a child clock and update the context to
match the parent's. We also update the relevant call sites in the
framework and drivers to use that new function.

Let's also add a test to make sure we avoid regressions there.

clk-divider instantiates clk_rate_request internally for its round_rate
implementations to share the code with its determine_rate

However, it's missing a few fields (min_rate, max_rate) that would be

Let's create the clk_hw_init_rate_request() function for clock providers
to be able to share the code to instation clk_rate_requests with the
framework. This will also be useful for some tests introduced in later
patches.

Multiple platforms (amlogic, imx8) return 0 when the clock rate cannot
be determined properly by the recalc_rate hook. Mention in the

bbd7a6cc38 clk: divider: Add re-usable determine_rate implementations
These are useful when running on 32-bit systems to increase the upper
supported frequency limit. clk_ops.round_rate returns a signed long
which limits the maximum rate on 32-bit systems to 2^31 (or approx.
2.14GHz). clk_ops.determine_rate internally uses an unsigned long so
the maximum rate on 32-bit systems is 2^32 or approx. 4.29GHz.

To avoid code-duplication switch over divider_{ro_,}round_rate_parent
to use the new divider_{ro_,}determine_rate functions.

30d6f8c15d clk: add api to get clk consumer from clk_hw
clk_register() is deprecated. Using 'clk' member of struct clk_hw is
discouraged. With this constraint, it is difficult for driver to
register clocks using the clk_hw API and then use the clock with
the consumer API

This adds a simple helper, clk_hw_get_clk(), to get a struct clk from
a struct clk_hw. Like other clk_get() variant, each call to this helper
must be balanced with a call to clk_put(). To make life easier on the
consumers, a memory managed version is provided as well.
