The series adds support for spread spectrum clocking for i.MX8MN
PLLs (audio, video and DRAM). It has been tested for the video PLL on
a board using i.MX8MN.

The patches added in version 4, such as the dt-bindings and the driver
for anatop, were inspired by the extensive email exchange from version 3:
https://lore.kernel.org/imx/20241106090549.3684963-1-dario.binacchi@amarulasolutions.com/

The series added spectrum spread support for the imx8mn platform only,
but in case it was merged, confirming that the directives and suggestions
made by the maintainers were correctly understood and implemented, I will
extend this support to the imx8mm and imx8mp platforms as well.

Changes in v6:
- Merge patches:
  10/20 dt-bindings: clock: imx8mm: add binding definitions for anatop
  11/20 dt-bindings: clock: imx8mn: add binding definitions for anatop
  12/20 dt-bindings: clock: imx8mp: add binding definitions for anatop
  to
  05/20 dt-bindings: clock: imx8m-anatop: define clocks/clock-names
  now renamed
  05/18 dt-bindings: clock: imx8m-anatop: add oscillators and PLLs
- Split the patch
  15/20 dt-bindings-clock-imx8m-clock-support-spread-spectru.patch
  into
  12/18 dt-bindings: clock: imx8m-clock: add PLLs
  16/18 dt-bindings: clock: imx8m-clock: support spread spectrum clocking

Changes in v5:
- Fix compilation errors.
- Separate driver code from dt-bindings

Changes in v4:
- Add dt-bindings for anatop
- Add anatop driver
- Drop fsl,ssc-clocks from spread spectrum dt-bindings

Changes in v3:
- Patches 1/8 has been added in version 3. The dt-bindings have
  been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The
  anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a
  syscon, so it represents a memory area accessible by ccm
  (imx8m-clock.yaml) to setup the PLLs.
- Patches {3,5}/8 have been added in version 3.
- Patches {4,6,8}/8 use ccm device node instead of the anatop one.

Changes in v2:
- Add "allOf:" and place it after "required:" block, like in the
  example schema.
- Move the properties definition to the top-level.
- Drop unit types as requested by the "make dt_binding_check" command.

Unlike audio_pll1 and audio_pll2, there is no video_pll2. Further, the
name used in the RM is video_pll. So, let's add the IMX8MM_VIDEO_PLL[_*]
definitions to be consistent with the RM and avoid misunderstandings.

The IMX8MM_VIDEO_PLL1* constants have not been removed to ensure
backward compatibility of the patch.

No functional changes intended.

The patch, which simply replaces video_pll1 with video_pll, highlights
many warnings raised by checkpatch.pl. These are not generated by the
changes made but are inherited from how the module was originally
written. Fixing them would have meant "obscuring" the actual changes
introduced.

(no changes since v5)

Changes in v5:
- Split the patch dropping the dt-bindings changes.

Changes in v4:
- New

Unlike audio_pll1 and audio_pll2, there is no video_pll2. Further, the
name used in the RM is video_pll. So, let's add the IMX8MP_VIDEO_PLL[_*]
definitions to be consistent with the RM and avoid misunderstandings.

The IMX8MP_VIDEO_PLL1* constants have not been removed to ensure
backward compatibility of the patch.

No functional changes intended.

Unlike audio_pll1 and audio_pll2, there is no video_pll2. Further, the
name used in the RM is video_pll. So, let's rename "video_pll1" to
"video_pll" to be consistent with the RM and avoid misunderstandings.

No functional changes intended.

---
The patch, which simply replaces video_pll1 with video_pll, highlights
many warnings raised by checkpatch.pl. These are not generated by the
changes made but are inherited from how the module was originally
written. Fixing them would have meant "obscuring" the actual changes
introduced.

(no changes since v5)

Changes in v5:
- Split the patch dropping the dt-bindings changes.

Changes in v4:
- New

Though adding clocks and clock-names properties will break the ABI,
it is required to accurately describe the hardware. Indeed, the anatop
module uses the input oscillators to generate various PLLs. In turn,
the Clock Control Module (CCM) receives clocks from the PLLs and
oscillators and generates clocks for on-chip peripherals.

Furthermore, as agreed in [1], this change represents the first step
toward the implementation of the anatop driver. Currently, in fact,
there is no dedicated anatop driver, but the CCM driver parses the
anatop node and registers the PLLs it produces.

Support NXP i.MX8M anatop PLL module which generates PLLs to CCM root.
By doing so, we also simplify the CCM driver code. The changes are
backward compatible.

Though adding the PLLs to clocks and clock-names properties will break
the ABI, it is required to accurately describe the hardware. Indeed,
the Clock Control Module (CCM) receives clocks from the PLLs and
oscillators and generates clocks for on-chip peripherals.

The addition of DT bindings for enabling and tuning spread spectrum
clocking generation can be applied specifically to the PLLs.

The "" value for the fsl,ssc-method property is specifically intended to
specify a "no SSC" case, as in the example, when you don't want to
configure spread spectrum for one of the PLLs, thus avoiding the use of
a method that would only make sense if SSC were being set.

---

Changes in v6:
- Improve the commit message
- change minItems from 7 to 1 for all the ssc properties added
- change maxItems from 10 to 4 for alle the ssc properties added
- update the DTS example

Changes in v4:
- Drop "fsl,ssc-clocks" property. The other added properties now refer
  to the clock list.
- Updated minItems and maxItems of
  - clocks
  - clock-names
  - fsl,ssc-modfreq-hz
  - fsl,ssc-modrate-percent
  - fsl,ssc-modmethod
- Updated the dts examples

Changes in v3:
- Added in v3
- The dt-bindings have been moved from fsl,imx8m-anatop.yaml to
  imx8m-clock.yaml. The anatop device (fsl,imx8m-anatop.yaml) is
  indeed more or less a syscon, so it represents a memory area
  accessible by ccm (imx8m-clock.yaml) to setup the PLLs.

Changes in v2:
- Add "allOf:" and place it after "required:" block, like in the
  example schema.
- Move the properties definition to the top-level.
- Drop unit types as requested by the "make dt_binding_check" command.

Add support for spread spectrum clock generation for the audio, video,
and DRAM PLLs.

Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com>

---

Changes in v6:
- Merge patches:
  10/20 dt-bindings: clock: imx8mm: add binding definitions for anatop
  11/20 dt-bindings: clock: imx8mn: add binding definitions for anatop
  12/20 dt-bindings: clock: imx8mp: add binding definitions for anatop
  to
  05/20 dt-bindings: clock: imx8m-anatop: define clocks/clock-names
  now renamed
  05/18 dt-bindings: clock: imx8m-anatop: add oscillators and PLLs
- Split the patch
  15/20 dt-bindings-clock-imx8m-clock-support-spread-spectru.patch
  into
  12/18 dt-bindings: clock: imx8m-clock: add PLLs
  16/18 dt-bindings: clock: imx8m-clock: support spread spectrum clocking

Changes in v5:
- Fix compilation errors.
- Separate driver code from dt-bindings

Changes in v4:
- Add dt-bindings for anatop
- Add anatop driver
- Drop fsl,ssc-clocks from spread spectrum dt-bindings

Changes in v3:
- Patches 1/8 has been added in version 3. The dt-bindings have
  been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The
  anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a
  syscon, so it represents a memory area accessible by ccm
  (imx8m-clock.yaml) to setup the PLLs.
- Patches {3,5}/8 have been added in version 3.
- Patches {4,6,8}/8 use ccm device node instead of the anatop one.

Changes in v2:
- Add "allOf:" and place it after "required:" block, like in the
  example schema.
- Move the properties definition to the top-level.
- Drop unit types as requested by the "make dt_binding_check" command.

Please list the items. You rely here on this being in strict order, so
this should be explicit, instead of just "in example" in the
description.

items:
  - description: audio_pll1

I guess here listing items might not work, so:

  The modulation techniques for each clock supporting spread
  spectrum, in this order: audio_pll1, audio_pll2, dram_pll and video_pll

Everything looks good for me, so with above changes:

drop the guarding macros, then this could be reused by i.MX9.

how about change to
struct clk_hw *imx_anatop_get_clk_hw(int id, struct device_node *np)?

Then no need to find the compatible for every function call.

I designed this function so that the caller, i.e., the CCM driver,
would no longer need to
reference the anatop compatible in any way, but I agree with you that
it would be better
 to add the np parameter. Do you think it would then make sense to add
a phandle to the
 anatop node in the clk node?

clk: clock-controller@30380000 {
    compatible = "fsl,imx8mn-ccm";
    ...
    fsl,anatop = <&anatop>
}

So that we can call
anatop_np = of_parse_phandle(np, "fsl,anatop", 0);
instead of
anatop_np = of_find_compatible_node(NULL, NULL, "fsl,imx8mn-anatop");
This would require an additional patch to
Documentation/devicetree/bindings/clock/imx8m-clock.yaml,
but it would make the CCM driver code more generic.

What do you think? I’m waiting for your response before sending version 7.

Thanks and regards,
Dario

This needs binding update, so needs DT maintainers to approve.
I am fine with it.
