Just to make sure when I get the question, you all co-developed this
patch, right?

Why do you use a default of 2? In particular since you reduce it to 1 in
/soc...

To avoid having people start sending patches that changes the sort order
as soon as I merge this, could you please sort your nodes by address
(not applicable for this one), then by node name alphabetically, then by
label alphabetically.

The purpose of the remoteproc driver's vote is to keep the rails powered
while we're booting the remote, in the event that Linux decides to
suspend and turn of the power rails while we're waiting...
Once the remote pulls the "handover" interrupt, it signals that it has
cast the necessary votes and need no more hand-holding.
So it's unlikely that _AO is the right choice here.

This belongs up by the other smp2p node.

You asked that before, and I took a note of the answer but, then because
I was away from the main machine when I sent V2, I didn't have the log.
Here's what I wrote down.
" - address-cells/size-cells = 1 in /soc - Bjorn
I experimentally changed address/cell sizes to 2
I'm finding that lk chokes "
So AFAIR LK was unhappy about changing the top level address/size cells
to <1> <1> and converting the /soc address/size cells to <2> <2> caused
a number of breakages during boot.
To be honest, this pattern is copied from the msm8916.dtsi original.
msm8953.dtsi has the same thing. msm8994 too, and 8998.
If you think it needs changing, then I'll have to see what can be done
with soc@{} entries.

ah. I sorted the contents of soc. I missed the upper level groupings.

Yes, it's probably just VDDMX isn't it.
I'll change that.

Sounds like problems not worth pursuing further. How about leaving a
comment for the next person here about LK's expectation of these being
2?

Why are you adding a dummy power domain here? IMO this would be better
added together with CPR. Especially because I would expect two power
domains here later ("mx", "cpr"). For cpufreq you also need to make
votes for the "MSM8939_VDDMX" power domain.

Please add the CPR items later together with CPR. This will make the
review a bit easier because we don't need to check that these are right
for the initial submission.

As I mentioned a already in a direct email at some point, AFAIU adding
interconnects should be an [almost-] all or nothing step. If you only
add interconnects for MDP then everything else that needs bandwidth will
either break or only continue working as a mere side effect of MDP
voting for permanent high bandwidth.
This could break easily if someone has a board without display, or if
the MDP5 driver is optimized to request the minimum necessary bandwidth
only.
I think strictly speaking "interconnects" properties are needed for
everything that uses DMA, i.e. CPUs, SDHCI, USB, UART, I2C, SPI and also
audio (in DSP bypass mode only). If you look at newer platforms they do
have "interconnects" for most of these.
(Semi-related side note: "register-mem" is neither documented nor used
anywhere in the code?)

Why is MDSS_GDSC defined again here? The parent-child relationship of
MDSS->MDP should ensure that the MDSS_GDSC from the parent mdss node
is on when dsi is.

Does this work? Confusingly, BYTE1/PCLK1_CLK_SRC can only have dsi0pll
as parent in gcc-msm8939 and not the dsi1pll. <&dsi_phy1 0/1> is not a
valid parent for those clocks.
Actually I cannot find any mention of mdss_dsi1_pll at all in
downstream. It seems a bit like the PLL functionality in dsi_phy1 is
unused and the PLL in dsi_phy0 is used for both DSI interfaces instead.
No idea why. If this is the case then assigned-clock-parents should
refer to dsi_phy0 here.

These timer interrupts are still wrong. GIC_SPI 8/7 belong to the timer
frame of the other cluster, 0x0b121000 instead of 0x0b021000.
You need to change the reg addresses like in
https://github.com/msm8916-mainline/linux/commit/0905a152ccb6fe6b94e8c16767993f05c608089c
OR, alternatively: Fix all the interrupt numbers. From the LK source
code we know that this timer frame specifically has GIC_SPI 257 as one
of its interrupts, because LK is making use of it:
https://git.codelinaro.org/clo/la/kernel/lk/-/blob/caf_migration/LA.BR.1.2.9.1_rb1.5/platform/msm8916/include/platform/irqs.h#L47-48
The other timer frames are likely also connected to some other interrupt
number that you might find in documentation or using experiments.
But the easier solution would be keeping the interrupts and just
changing the "reg"s.

I'm pretty sure there's binding checks that demand this but, I will
re-verify it.

I will excise this if I can, i.e. if the system will still boot once done.

We did discuss that. You'll also recall we concluded we would have to
revert this patch to make that happen.
commit 76a748e2c1aa976d0c7fef872fa6ff93ce334a8a

interconnect: qcom: msm8939: Use icc_sync_state
but then why not revert for all of these SoCs too ?
drivers/interconnect/qcom/msm8939.c: .sync_state = icc_sync_state,
drivers/interconnect/qcom/msm8974.c: .sync_state = icc_sync_state,

until such time as we have an all or nothing interconnect setup for each
of those SoCs ?
Yes I take your point "some peripherals will appear to work only as a
result of the AHB vote the MDP casts here" but, that is a bug in the
definition of that hypothetical peripheral.
The MDP/display won't run without the interconnect here and the only way
to pull it is to remove sync_state which begs the question why not pull
sync_state for all SoCs without a perfect interconnect description ?
I think that would be a retrograde step.

Oh do you have me there though, this is a holdover from the Android
dtsi. I'll see if it makes a difference dropping this.

Parent clock is gpll0a but they waggle different rcgr addresses
static struct clk_rcg2 byte0_clk_src = {
.cmd_rcgr = 0x4d044, <- here

.parent_map = gcc_xo_gpll0a_dsibyte_map,

It *should* work even with the wrong name but, I will send a GCC update
to address the naming, which looks wrong.

Most of the SoCs you list do have "interconnects" defined for most
components, which means the situation for them is quite a different
level. It's probably not necessary to have the interconnect setup
absolutely perfect before enabling it. However to avoid frustration for
people with slightly different board setups it should at the very least
cover more than one component.
Should the icc_sync_state() change be reverted for some of these SoCs?
If you ask me: Yes!
Perhaps a real example makes my concern more understandable: As I
mentioned, you rely on MDP providing the necessary bandwidth for the
entire system. This works fine in your case, but it can happen easily
that MDSS/MDP is not enabled at all, e.g.:
- On a board without display.
- During early bring-up: I usually start with UART, USB and SDHCI
before I even think about enabling the display.
I simulated this on the BQ Aquaris M5 (MSM8939) that has most
functionality set up already in postmarketOS. First the results without
any changes (interconnects enabled like in your patch here):
-> Boots into rootfs in about *18 seconds*, feels fine
Now I just disable MDSS in the device tree and boot again:
&mdss {
status = "disabled";
};
-> Boots into rootfs in about *80 seconds*, everything feels sluggish
This is 4 times the normal boot time, and nothing in dmesg tells me that
it's because I don't have display enabled. Someone porting a new device,
especially without UART, might have given up already before waiting so
long. Plus, what would I do to fix this on a board without display? :/
Now I try removing icc_sync_state:
-> Boots into rootfs in about 17 seconds, feels fine
IMO it is clear that adding icc_sync_state() too early is a bad idea,
and *will* break some setups.

8974 defines two interconnects one for the mdp, one of the gpu. So a
headless setup as you describe would encounter the same situation
potentially.

To me, that is indicative of more work being required to vote
appropriately for required bandwidth - AHB clocks basically in our
hypothetical setup.
The display certainly won't work without voting for bandwidth it needs.
If there's work to be done to _enable_ headless mode - and there is, we
can do the work to figure out who isn't voting for bandwidth.
Probably the CPU - absent cpufreq, CPR, the operating points. A good -
probably correct guess is we aren't ramping cpufreq, aren't ramping CCI
and aren't voting for the inter-chip CCI "front side" so when the system
boots headless and "does stuff" the cpufrequency stays low, the votes
aren't cast and everything seems to crawl.
I still think its a contrived example though. CPR will come right after
the core dtsi and we can put the theory to the test.

For the record here's the downstream _AO is what it says

But *this* is the downstream

qcom,pronto-vddmx-supply = <&pm8916_l3_corner_ao>;

it is an _ao

Confirmed power-domain is a required property, dtbs check will complain
without it.
