MT8188 is a SoC based on 64bit ARMv8 architecture.
It contains 6 CA55 and 2 CA78 cores.
MT8188 share many HW IP with MT65xx series.
This patchset was tested on MT8188 evaluation board to shell.
Based on tag: next-20231018, linux-next/master
Changes in v5:
- Remove unnecessary always-on regulator nodes
- Fix dtbs_check warning
Changes in v4:
- Explain the reason of modifying pwrap binding file, and correct the
subject
- Fix reviewer's comments
Changes in v3:
- Remove the duplicated part of mt8188 in the pwrap yaml file
- Fix reviewer's comments about coding style
Changes in v2:
- Add MT8188 PMIC Wrapper compatible to binding document
- Fix reviewer's comments

From: jason-ch chen <[email protected]>
The reason for changing the patch was that while MT8188 uses the same
pwrap as MT8195, the original code was only applicable to 'compatible =
"mediatek,mt8188-pwrap"'. To resolve the DTBS check warning that
'['mediatek,mt8188-pwrap', 'mediatek,mt8195-pwrap', 'syscon'] is too
long', it is necessary to modify the code.

MT8188 is a SoC based on 64bit ARMv8 architecture. It contains 6 CA55
and 2 CA78 cores. MT8188 share many HW IP with MT65xx series.
We add basic chip support for MediaTek MT8188 on evaluation board.

NACK. You're not specifying the L2 cache correctly.
Hint: the missing properties are
cache-size
cache-line-size
cache-sets

Same here. Please properly define the L2 cache.

And again.
This SoC has 256KB L2 shared between the two A78 cores, 128KB L2 shared
between the A55 cores, and 2MB of L3 cache shared across all.

Question: Is the ARM DSU PMU broken also on this SoC's TZ firmware?!

You don't need reg-names here but anyway, if you really want to keep that, please
no underscores when possible.

> Question: Is the ARM DSU PMU broken also on this SoC's TZ firmware?!
Because of security concerns, the default configuration of the ARM
trusted firmware does not include enabling the ARM DSU PMU.
However, it is possible to add a patch to enable this feature. The
patch https://crrev.com/c/4885752 has not been merged into TF-A yet.
We are currently considering upstreaming it.
In the next version, I will rectify the issues mentioned in the other
comments. Thank you for your review.

MediaTek IOT is working on the very latest Ubuntu and Suse installation
but encountered this problem, too.
I've tested this patch 'https://crrev.com/c/4885752' but it seems just
not working and we still encounter the same problem before we disable
arm_dsu_pmu module. IOT uses trusted-firmware a v2.6 currently, however
I think this solution is the very common code should be able to applied
to v2.6~v2.8.
After tested the patch, we still got the same error log with repeated
msdc request timeout.
[ 27.998999][ T52] mtk-msdc 11230000.mmc: msdc_request_timeout:

Then sometimes we got these logs maybe caused by arm_dsu_pmu.

The only solution I've tested working is which I've posted before when
discussion set 'arm_dsu_pmu' to 'fail' in mt8195.dtsi.

There's an another issue.
Could you help to upstream USB port with mtu3 enabled.
I've heard that the limitation for mtu3 and xhci port has be resolved
for MT8188. If you could upstream mtu3 nodes in MT8188.dtsi that will
help for testing mtu3 on all Chromebook platforms. Otherwise MediaTek
IOT will need to upstream mtu3 nodes to MT8188.dtsi later but we have no
Chromebook platforms to test.
Thanks

The main objective of this series is to submit basic DTS. There will be
other features that will be developed and integrated based on this DTS
after it is upstreamed. Your requirement can be addressed in future
series.
Thanks,
Jason
