PATCH v3 1/3 clk: qcom: rcg: update the DFS macro for RCG

Update the init data name for each of the dynamic frequency switch controlled clock associated with the RCG clock name, so that it can be generated as per the hardware plan. Thus update the macro accordingly.

PATCH v3 2/3 dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

In reply to Taniya Das

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

Re: [PATCH v3 2/3] dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

Hi Taniya,

not a full review, just a couple of things I noticed, comments inline.

Quoted 3 lines · Taniya Das

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

I would suggest to split this in two:

1. conversion to YAML
2. add SC7180 header and example

IIUC the ids correspond to GCC_GPLL0_MAIN_DIV_CDIV and GPLL0. If that is correct I guess the intention is to use the constants in the DT?

Re: [PATCH v3 2/3] dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

Hi Matthias,

Thank you for your review.

Hi Taniya,

not a full review, just a couple of things I noticed, comments inline.

On Wed, Sep 18, 2019 at 03:20:17PM +0530, Taniya Das wrote:

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

I would suggest to split this in two:

1. conversion to YAML
2. add SC7180 header and example

I will split the patch.

IIUC the ids correspond to GCC_GPLL0_MAIN_DIV_CDIV and GPLL0. If that is correct I guess the intention is to use the constants in the DT?

Re: [PATCH v3 2/3] dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

In reply to Taniya Das
Quoted 3 lines · Taniya Das

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

I'm fine fixing errors in the conversion, but adding a new chip should be separate patch.

Re: [PATCH v3 2/3] dt-bindings: clk: qcom: Add YAML schemas for the GCC clock bindings

Hi Rob,

Thanks for your comments.

Quoted 8 lines · Rob Herring

The GCC clock provider have a bunch of generic properties that are needed in a device tree. Add a YAML schemas for those. Also update the compatible for SC7180 along with example for clocks & clock-names.

I'm fine fixing errors in the conversion, but adding a new chip should be separate patch.

Sure, will take care of splitting the patch.

Does this pass 'make dt_binding_check' as 'clocks' is required.

I will fix it in the next patch.

Can this be restricted to certain compatible strings where this is the case? I'd like to be able to confirm that the compatibles that expect to see the nvmem actually have it.

I will add this in the next patch.

PATCH v3 3/3 clk: qcom: Add Global Clock controller (GCC) driver for SC7180

In reply to Taniya Das

Add support for the global clock controller found on SC7180 based devices. This should allow most non-multimedia device drivers to probe and control their clocks.

Again, nobody has fixed the UFS driver to not need to do this halt skip check for these clks? It's been over a year.

The UFS_PHY_RX/TX clocks could be left enabled due to certain HW boot configuration and thus during the late initcall of clk_disable there could be warnings of "clock stuck ON" in the dmesg. That is the reason also to use the BRANCH_HALT_SKIP flag.

I would also check internally for the UFS driver fix you are referring here.

Does this assume the display is left enabled out of the bootloader? Why is this critical to system operation? Maybe it is really CLK_IGNORE_UNUSED?

This clock is not kept enabled by bootloader. But leaving this ON for clients on config noc.

Again, nobody has fixed the UFS driver to not need to do this halt skip check for these clks? It's been over a year.

Quoted 4 lines

The UFS_PHY_RX/TX clocks could be left enabled due to certain HW boot configuration and thus during the late initcall of clk_disable there could be warnings of "clock stuck ON" in the dmesg. That is the reason also to use the BRANCH_HALT_SKIP flag.

Oh that's bad. Why do the clks stay on when we try to turn them off?

I would also check internally for the UFS driver fix you are referring here.

Sure. I keep asking but nothing is done :(

Why does this need halt_skip?

This is required as the source is external PHY, so we want to not check for HALT.

This doesn't really answer my question. If the source is an external phy then it should be listed as a clock in the DT binding and the parent should be specified here. Unless something doesn't work because of that?

There's no parent though... So I guess this means it keeps it enabled implicitly in hardware?

These are not left enabled, but want to leave them enabled for clients on config NOC.

Sure. It just doesn't make sense to create clk structures and expose them in the kernel when we just want to turn the bits on and leave them on forever. Why not just do some register writes in probe for this driver? Doesn't that work just as well and use less memory?

will add this header.
Currently the <drivers/clk/qcom/clk-regmap.h> already includes it.

Yes but it should be included in any clk-provider drivers too.

Does this assume the display is left enabled out of the bootloader? Why is this critical to system operation? Maybe it is really CLK_IGNORE_UNUSED?

Quoted 2 lines

This clock is not kept enabled by bootloader. But leaving this ON for clients on config noc.

Please see below comment for the other critical clk with no parent.

The UFS_PHY_RX/TX clocks could be left enabled due to certain HW boot configuration and thus during the late initcall of clk_disable there could be warnings of "clock stuck ON" in the dmesg. That is the reason also to use the BRANCH_HALT_SKIP flag.

Oh that's bad. Why do the clks stay on when we try to turn them off?

Those could be due to the configuration selected by HW and SW cannot override them, so traditionally we have never polled for CLK_OFF for these clocks.

This is required as the source is external PHY, so we want to not check for HALT.

This doesn't really answer my question. If the source is an external phy then it should be listed as a clock in the DT binding and the parent should be specified here. Unless something doesn't work because of that?

The USB phy is managed by the USB driver and clock driver is not aware if USB driver models the phy as a clock. Thus we do want to keep a dependency on the parent and not poll for CLK_ENABLE.

There's no parent though... So I guess this means it keeps it enabled implicitly in hardware?

These are not left enabled, but want to leave them enabled for clients on config NOC.

Sure. It just doesn't make sense to create clk structures and expose them in the kernel when we just want to turn the bits on and leave them on forever. Why not just do some register writes in probe for this driver? Doesn't that work just as well and use less memory?

Even if I write these registers during probe, the late init check 'clk_core_is_enabled' would return true and would be turned OFF, that is the reason for marking them CRITICAL.

There's no parent though... So I guess this means it keeps it enabled implicitly in hardware?

These are not left enabled, but want to leave them enabled for clients on config NOC.

Sure. It just doesn't make sense to create clk structures and expose them in the kernel when we just want to turn the bits on and leave them on forever. Why not just do some register writes in probe for this driver? Doesn't that work just as well and use less memory?

Even if I write these registers during probe, the late init check 'clk_core_is_enabled' would return true and would be turned OFF, that is the reason for marking them CRITICAL.

That wouldn't happen if the clks weren't registered though, no?

I want to keep these clock CRITICAL and registered for now, but we should be able to revisit/clean them up later.

The UFS_PHY_RX/TX clocks could be left enabled due to certain HW boot configuration and thus during the late initcall of clk_disable there could be warnings of "clock stuck ON" in the dmesg. That is the reason also to use the BRANCH_HALT_SKIP flag.

Oh that's bad. Why do the clks stay on when we try to turn them off?

Those could be due to the configuration selected by HW and SW cannot override them, so traditionally we have never polled for CLK_OFF for these clocks.

Is that the case or just a guess?

This is required as the source is external PHY, so we want to not check for HALT.

This doesn't really answer my question. If the source is an external phy then it should be listed as a clock in the DT binding and the parent should be specified here. Unless something doesn't work because of that?

The USB phy is managed by the USB driver and clock driver is not aware if USB driver models the phy as a clock. Thus we do want to keep a dependency on the parent and not poll for CLK_ENABLE.

The clk driver should be aware of the USB driver modeling the phy as a clk. We do that for other phys so what is the difference here?

Let me check with the USB team, but could we keep them for now?

Ok. It's also the same as sdm845 so I guess it's OK. Would be nice to properly model it though so we can be certain the clk is actually enabled.

Could you please confirm if you are referring to update the below?

I wasn't suggesting that explicitly but sure. Something like this would be necessary to make clk_get() pass back a NULL pointer to the caller. Does everything keep working with this change?

Even if I pass back NULL, I don't see it working. Please suggest how to take it forward.

Why doesn't it work?

My bad, I messed up with the kernel and my testing was showing failures. Have tested it on SC7180 & Cheza and it works as expected.

I will submit the changes in common.c to return NULL.
