Exynos 8895 SoC is an ARMv8 mobile SoC found in the Samsung Galaxy
S8 (dreamlte), S8 Plus (dream2lte), Note 8 (greatlte) and the Meizu
15 Plus (m1891). Add minimal support for that SoC, including:

- All 8 cores via PSCI
- ChipID
- Generic ARMV8 Timer
- Enumarate all pinctrl nodes

Further platform support will be added over time.

I do not believe this was tested. See maintainer SoC profile for Samsung
Exynos.

Limited review follows due to lack of testing.

Are there two pmus?

Hm? I think this was explicitly disallowed.

Keep order of properties, just like DTS coding style asks.

Anyway, fixed-rate-clocks wrapper is not needed, drop.

This does not look ordered. See DTS coding style.

Hm. The Downstream kernel has them all under one node with compatible

'arm,armv8-pmuv3', same as with Exynos 7885. So it should have two PMUs,

one for each cluster.


Considering the second cluster consists of Samsung's custom Mongoose M2

cores, what would be the most adequate thing to do? Keep the first PMU as

"arm,cortex-a53-pmu" and use the SW model "arm,armv8-pmuv3" for the

second PMU? I doubt guessing if these mongoose cores are based on already

existing cortex cores is a great idea.

It's weird. Without the clock-frequency property it fails early during the

boot process and I can't get any logs from pstore or simple-framebuffer.

Yet it's not set on similar platforms (exynos7885, autov9). Perhaps I

could alias the node and set it in the board device tree..? That doesn't

sound right.

This sounds like CNTFRQ_EL0 is not set properly by the firmware.
Now, if I read the documentation properly, this can be only set from
EL3, which in your case is... not easy.

On my Galaxy A8 2018 (Exynos7885) I remember the old Android 8
bootloader not being able to boot mainline, but Android 9 bootloaders
did. I did not take the time to check if it was related to this, but it
is my guess.

Your best bet is that maybe Samsung decided to fix this on the latest
bootloader, and upgrading will fix it. (Though if it's already on an
Android 9 based bootloader and it's still broken, my guess is a newer
version won't fix it, but who knows)

Or... Exynos8895 has a known bootrom vulnerability, you could force the
SoC into USB Download mode, and use the exploit to boot into a patched
bootloader. This is of course pretty tedious.

Your only actually relistic choice is submitting without this line and
manually adding it while actually using the phone (or making the
chainloaded bootloader/boot wrapper add it).

Not optimal, but it is what it is...

I was just wondering why there is only one and called a53. I am not sure
what should be for the second, but rather not a software model.

If you can update your device to newer Android and it fixes the issue,
then please drop the property. If this does not work, then please add a
comment like: /* Non-updatable, broken stock Samsung bootloader does not
configure CNTFRQ_EL0 */

Well, as far as I can tell there are 3 options:

- use an already defined PMU model for another core (ex. A73)

- submit another patch to add a custom mongoose-specific PMU model

- omit the mongoose cores PMU entirely

My guess is that omitting it entirely with a comment that mentions the

issue will be good enough, at least for now. Is that OK for the v3?
