Peter Griffin Dec. 1, 2023, 4:09 p.m. UTC
Google gs101 SoC is ARMv8 mobile SoC found in the Pixel 6,
(oriole) Pixel 6a (bluejay) and Pixel 6 pro (raven) mobile
phones. It features:
* 4xA55 little cluster
* 2xA76 Mid cluster
* 2xX1 Big cluster

This commit adds the basic device tree for gs101 (SoC).
Further platform support will be added over time.

Verified boot to a busybox console on my oriole device.

Thanks,

Nitpick: this empty line is not needed.

Still feels fishy to me that it was decided to have this file instead
of re-using existing Exynos constants. For example, in Exynos850 I
used common constants and it was ok, but it's not ok for this SoC,
althought they look *identical* in a sense of pinctrl. And all those
constants already exist, also identical. So I wonder why something
like this shouldn't be done for Exynos850 as well. But ok.

Please check commit f4324583cd4d ("arm64: dts: exynos: move aliases to
board in Exynos850"). At least for Exynos850 the serial alias was
moved to the board dts by Krzysztof.

Don't you already have real USI/UART clocks implemented in your clock driver?

Krzysztof, can you please advice which scheme is preferred right now:
sorting by name or by address? I saw your patch for dts style doc, but
just want to know the current state of affairs.

The same concern as above. I think I saw those clocks already
implemented in gs101 clock driver.

Doesn't CMU_APM take any clocks from CMU_TOP?

Just a suggestion: it might be relatively simple to add syscon-reboot
node in pmu_system_controller, and it might just work. One more
feature for free! :)

Use coding style, so sorting by unit address in DTSI and by
label/phandle of overrides in DTS.

Coding style was not yet applied, but I don't see any objections to it
so it is just a matter of days.

No, not yet, hence the dummy clock.

It is not required at the moment, as it is compatible with
samsung,exynos850-usi. I don't want to keep adding more patches to
this series, and then having an endless cycle of nits.

No, these clocks have not been implemented yet, hence the dummy clock.
There is no support for cmu_peric0 bank yet in the clock driver.

Thanks for the suggestion. I tried that previously and it is not
included here deliberately because it relies on more than that to be
functional. Although the register offsets are the same, the PMU
registers are protected from the kernel and are only write accessible
via SMC call on this platform. I have patches ready to send out as a
RFC for that once this initial series is merged and we can discuss
that then.

regards,

Peter.
