Subject: [PATCH 2/4] arm64: dts: qcom: add sdm845-google-blueline (Pixel 3)

From: Amit Pundir <[email protected]>

This adds an initial dts for the Blueline (Pixel 3). Supported
functionality includes display, Debug UART, UFS, USB-C (peripheral), WiFi,
Bluetooth and modem.

Bootloader compatible board and msm IDs are needed for the kernel to boot
with Pixel3 bootloader, so those are added.

GPIOs 0 through 3 and 81 through 84 are configured to not be accessible
from the application CPUs, so we mark them as reserved to allow the Pixel 3
to boot.

The reserved-memory locations where obtained from downstream using
kernel logs:
https://gist.github.com/calebccff/090d10bfac3cb9e9bd98dda30b054c96

The rmtfs region is allocated with UIO, making it technically "dynamic".
It's address and size can be read from sysfs:

blueline:/ # cat /sys/class/uio/uio0/name
rmtfs
at /sys/class/uio/uio0/maps/map0/addr
0x00000000f2701000
blueline:/ # cat /sys/class/uio/uio0/maps/map0/size
0x0000000000200000

Like the OnePlus 6, it needs 1kB reserved on either side of the rmtfs
memory to workaround some XPU bug which would otherwise cause erroneous
XPU violations when accessing the rmtfs_mem region.

For wifi, the pixel 3 reports a board-id of 0xFF, and downstream
only includes a single bdwlan file. The qcom,ath10k-calibration-variant
property is set to ensure that the correct calibration data is used.

These properties are already part of the sdm845.dtsi, so no need to have
them here.

Why are you using the oneplus6 here?

Ideally Kalle Valo should bless this string, added him to the Cc list.
Could you please submit the board file to the ath10k (see [1] for the
description and [2] for an example).

I haven't verified it, but I'd assume that the firmware for bits like
the remoteprocs are the same between the pixel 3 and 3 XL, hence using a
common name (same as the approach taken on the OnePlus 6/6T)

As Marijn just mentioned on IRC, the driver right now only calls
drm_dsc_pps_payload_pack() but doesn't actually send it. I haven't
investigated this myself but I'll look into it.

Unfortunately no datasheet afaik, they tend to be pretty elusive. The
things I would do for a phone panel datasheet...

as a side note: I checked the dtbo.img. There are three different
versions of the panel programming sequences in the included dtb files.
So you might want to check for the difference with
linux-mdss-dsi-panel-driver-generator.

Please use consistent naming, so if previous was "xxx-regulator", keep
similar pattern here.
