+* Clock bindings for NXP i.MX8M Quad
+
+Required properties:
+- compatible: Should be "fsl,imx8mq-ccm"
+- reg: Address and length of the register set
+- #clock-cells: Should be <1>
+- clocks: list of clock specifiers, must contain an entry for each required
+ entry in clock-names
+- clock-names: should include the following entries:
+ - "ckil"
+ - "osc_25m"
+ - "osc_27m"
+ - "clk_ext1"
+ - "clk_ext2"
+ - "clk_ext3"
+ - "clk_ext4"
+
+The clock consumer should specify the desired clock by having the clock
+ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx8mq-clock.h
+for the full list of i.MX8M Quad clock IDs.

The SCCG is a new PLL type introduced on i.MX8. Add support for this.
The driver currently misses the PLL lock check, as the preliminary
documentation mentions lock configurations, but is quiet about where
to find the actual lock status signal.

From: Lucas Stach <l.stach@pengutronix.de>
The SCCG is a new PLL type introduced on i.MX8. Add support for this.
The driver currently misses the PLL lock check, as the preliminary
documentation mentions lock configurations, but is quiet about where
to find the actual lock status signal.

Since a lot of clocks on imx8 are formed by a mux, gate, predivider and
divider, the idea here is to combine all of those into one composite clock,
but we need to deal with both predivider and divider at the same time and
therefore we add the imx_clk_composite_divider_ops and register
the composite clock with those.

Since a lot of clocks on imx8 are formed by a mux, gate, predivider and
divider, the idea here is to combine all of those into one composite clock,
but we need to deal with both predivider and divider at the same time and
therefore we add the imx_clk_composite_divider_ops and register
the composite clock with those.

From: Lucas Stach <l.stach@pengutronix.de>
Add driver for the Clock Control Module found on i.MX8MQ.
This is largely based on the downstream driver from Anson Huang and
Bai Ping at NXP, plus the imx composite clock from Abel Vesa at NXP,
with only some small adaptions to mainline from me.

From: Lucas Stach <l.stach@pengutronix.de>
Add driver for the Clock Control Module found on i.MX8MQ.
This is largely based on the downstream driver from Anson Huang and
Bai Ping at NXP, plus the imx composite clock from Abel Vesa at NXP,
with only some small adaptions to mainline from me.

You assing a value to 'rate' here.

And then overwrite it immediately after.
Is this really the intended behavior?

It's:
rate = *prate / prediv_value;
rate = rate / div_value;
To me this looks correct. However, For an unsigned long type we have
DIV_ROUND_UP() with which we do not need any casting. For 64bit code
unsigned long is 64bit anyway which makes the cast a no-op and for 32bit
code there's also no point in exanding the initial 32bit value to 64bit.

Yes, this looks correct. Thanks for the feedback.

That's a good point too.

Can you point to the downstream driver so we can know what small
adaptations were made.

Can you please add a comment indicating why this can't be done with a
platform driver, or convert this to be a platform driver?

Looks the same as another patch, maybe it is?
Anyway, same nitpick about returning the DIV_ROUND_UP_ULL() result.

Didn't I already review this? I'd prefer we move this to using clk_hw
based APIs and then return the clk pointer if needed.

Do this case statement before allocating? So that kfree() isn't required

Any chance to use clk_hw based registration APIs?

And parent_rate can't overflow if it's a u32? Maybe it could be a u64 so
that we don't need casting later on in this function.

Yes, you reviewed the v11, so you can ignore this 9th version.
I'll implement all the comments from you in the 12th version before sending.
I'll also switch all clk based register functions call sites
to clk_hw based ones.

No. So basically both pll1 and pll2 and the divider after it form together this SCCG:
https://www.nxp.com/docs/en/reference-manual/IMX8MDQLQRM.pdf#page=834
See: Figure 5-8. SSCG PLL Block Diagram
We're basically reading the input of the pll 1 in order to compute the output of the entire SCCG.
I know it's a mess. I'm working on cleaning it up, but for now we need this in in order to boot up.

Since the SCCG is contructed by multiple different types of clocks here, the equation doesn't help
since it is spread in all constructing blocks.

It's was implemented originally in NXP's internal tree. The adaptations
to the initial implementation are not that small anymore. I even changed the
authorship since it has changed quite a lot compared to the initial version.

The comment does not apply anymore. It is remoed in the next version.
When the driver was initially implemented, the specs doc was not ready.

Since a lot of the imx clocks that are already upstream and since it's not
quite a small change, I would prefer if this would go in as is. I intend to
make the switch to clk_hw based registration later, but it will take some time
for me to get that ready and that would delay the upstream of imx8mq drivers
even more.
All the new clock types introduced now are clk_hw based.

Fair enough. Removed entirely in the next version. Each driver will set its

So I'm doing this in our internal tree first to make sure I don't break the
other (newer) socs.
I already have a prototype in testing but it's a long way to upstream it.
Basically, I'm replacing all of this with a single, more like a composite,
more complex, clock type that does all the magic inside.
One of the problems is the fact that the bypasses can have the same sources
and in my case, I'm implementing that as a list of parents name, but the
parent names list doesn't work with duplicates, so I have to find some other
way to do it.
Once I have something clean and tested enough I'll send it upstream.

Just to avoid any kind of confusion.
The whole refactoring of the SCCG clock will be done in a separate (later) change
and will not be part of this patchset.
I already sent the 12th version of this current patch series and I would really
like to get this in ASAP so that the booting up of imx8mq will not be delayed.
Thanks

Ok. Well we're in rc1 right now, and so we're not merging new drivers
into mainline. I can merge the clk driver into clk-next, but you'll have
to wait for the stabilization period to end (approximately 6 or 7 weeks)
before this can get into the next kernel version. It will be in
linux-next much sooner of course.

That would be great if you can help that.
We're now working with SUSE to enable i.MX8 support.
Their criteria is only backporting patches which must be at least in maintainer's
next tree already. So either picked up by you or Shawn would help a lot on it.
BTW, one simple question is that because MX8MQ DTS patches depends on
this clock driver series. How would you suggest this series to go through
your tree or Shawn's tree?

Once Stephen has a topic branch for the patches, I can pull it into my
tree to resolve the DT dependency.
