[PATCH 1/3] arm64: dts: qcom: milos: Reduce rmtfs_mem size to 2.5MiB

[Alexander Koskovich]

The rmtfs_mem region is currently sized at 6MiB but the default for
milos downstream is 2.5MiB. This causes remoteproc crashes on devices
that expect the smaller size:

modem_ac.c:281:Access Control Error: Could not protect the region specified:Start:e1f00000 End:e2180000, PID:1

Reduce the default to 2.5MiB to match the QCOM downstream config, and
override the size for FP6.

[PATCH 3/3] arm64: dts: qcom: Add the Nothing Phone (3a)

[Alexander Koskovich]

Add a devicetree for the Nothing Phone (3a) smartphone, which is based
on the Milos/SM7635 SoC.

Supported functionality as of this initial submission:
* Camera flash/torch LED
* Debug UART
* Glyph LEDs (AW20036)
* PMIC-GLINK (Charger, Fuel gauge, USB-C mode switching)
* Assistant Key, Power Button, Volume Keys
* Regulators (PM7550, PM8550VS, PMR735B)
* Remoteprocs (ADSP, CDSP, MPSS, WPSS)
* USB (USB2 + FSA4480)

You didn't actually Cc me, but I found it on the mailing list anyways :)

Yes, it's intentional that it's 6 MiB on Fairphone (Gen. 6):

https://gerrit-public.fairphone.software/plugins/gitiles/platform/vendor/qcom/proprietary/devicetree/+/b3744ffef87e1f2a232b26e9cb270a1f82554bc3%5E!/

I think Fixes is appropriate since the default for Milos should be
0x280_000 and not 0x600_000?

Fixes: d9d59d105f98 ("arm64: dts: qcom: Add initial Milos dtsi")

And maybe a comment like this on top of the node?

/* Increase the size from 2.5 MiB to 6 MiB */

Anyways:
