Why no cover letter?

"clock" is redundant in all these descriptions. Please remove.

And "_clk" postfix is redundant in all these strings. Remove?

The clk_init_data can be const too, right?

I didn't have anything useful to write in it. Will provide you one in

You don't think it's a little bit odd to have description such as
"Sleep", "PCIe 2a pipe" or First EMAC controller reference"?

I mean I agree that it's obviously clocks we're talking about, but to me
that makes it seems like the descriptions are cut short, just for the
sake of avoiding "clock".

In this case I think they should include _clk, as they actually matches
the clock names in the documentation.

Alright, keeping clock is OK as long as

there is a better name for this and the other non-word descriptions.

I'd really rather not have clock-names at all because we spend a bunch
of time comparing strings with them when we could just as easily use
a number.

I know that you would like to get rid of the clock-names for the clock
controllers. I've looked at it since and while it will be faster to
execute I still feel that it's going to be harder to write and maintain.

E.g. look at gcc_pcie_4_pipe_clk_src, its parents today are
pcie_4_pipe_clk and bi_tcxo. Something I can reason about being correct
or not.

If we ditch the clock-names I will have:

static const struct clk_parent_data gcc_parent_data_14[] = {
        { .index = 30 },
        { .index = 0 },
};

Generally we would perhaps use some compile time constant, but that
won't work here because we're talking about the index in the clocks
array in the yaml.


But perhaps I'm missing something that would make this manageable?

Bjorn

Those numbers could have some #define.

	{ .index = PCIE_4_PIPE_CLK_DT }
	{ .index = BI_TCXO_DT }

I dunno. Maybe a macro in the dt-binding header could be used to specify
the 'clocks' property of the DT node that is providing the other side?
The idea is to make a bunch of macros that insert the arguments of the
macro in the right place for the clocks property and then define the
order of arguments otherwise. It would be similar to how
CREATE_TRACE_POINTS is used in include/trace/define_trace.h 

In the dt-bindings/qcom,gcc-soc.h file:

	#ifdef IN_DTSI

	#undef GCC_DT_NODE_CLOCKS
	#define GCC_DT_NODE_CLOCKS
		clocks = <BI_TCXO_DT>,
			 <SLEEP_CLK_DT>;

	#endif /* IN_DTSI */

	#define BI_TCXO_DT 0
	#define SLEEP_CLK_DT 1


And then in the SoC.dtsi file have

	#define IN_DTSI
	#include <dt-bindings/qcom,gcc-soc.h>

	#define BI_TCXO_DT	&xo_board
	#define SLEEP_CLK_DT	&sleep_clk

	...

	clock-controller@a000000 {
		compatible = "qcom,gcc-soc";
		reg = <0xa000000 0x10000>;
		GCC_DT_NODE_CLOCKS
	};


and then in drivers/clk/qcom/gcc-soc.c file:

	#include <dt-bindings/qcom,gcc-soc.h>

	static const struct clk_parent_data gcc_parent_data_14[] = {
		{ .index = PCIE_4_PIPE_CLK_DT },
		{ .index = BI_TCXO_DT },
	};

The benefit I see to this is that the index for each clock is in the
header file (BI_TCXO_DT is 0) and it's next to the clocks property.
Someone could still mess up the index based on where the macro is used
in the clocks property though.

Isn't this being an overkill, to define exact properties in the bindings 
header? Also this would mean that we'd have to add dt-binding headers 
for all _consumers_ of clocks. And to make things more complex, e.g. for 
PCIe devices different instances of the device would use different 
amount of clocks. This would mean that we'd have to define 
SM8250_PCI0_CLOCKS, SM8250_PCIE1_CLOCKS and SM8250_PCIE2_CLOCKS.


If we were to switch to this fragile path of using indices (yes I 
consider it to be very fragile), I'd consider something like the 
following to work in the platform dtsi file:

clocks =
BEGIN_CLOCK
CLOCK(BI_TCXO_DT, &bi_tcxo)
CLOCK(SLEEP_CLK_DT, &sleep_clk)
END_CLOCK;

While the following should give an error:
clocks =
BEGIN_CLOCK
CLOCK(SLEEP_CLK_DT, &sleep_clk)
CLOCK(BI_TCXO_DT, &bi_tcxo)
END_CLOCK;

I think we can make this error out by using some additional tool (or 
additional preprocessor pass over the sources)

And actually might I suggest an alternative approach to manually using 
indices everywhere? What about spending the time once during the boot to 
convert .fw_name and clock_names to parent indices during clock 
registration and then using them for all the further operations?

BI_TCXO_DT is not the value, its the index of the entry in the clocks
array. And the actual values of the clock controller's clocks
property is not a property of the clock controller, but the system
definition.

I.e. that should be clear and explicitly expressed in the dts.

Let's not invent some magical syntax for describing the clocks in the
DT.

These macros can't expand to sparse arrays anyways, so iiuc this would
give a sense that the ordering might not be significant, when it really
is.

I'm pretty sure that's what clk_core_fill_parent_index() already does.

In this case I think we should go for clock-name in the DT and
auto-flled indices inside. Stephen, WDYT? Would that fix your concern
for comparing strings each and every time?
