Subject: [PATCH v2 2/3] arm64: dts: qcom: msm8916-samsung-fortuna: Add initial device trees

From: Walter Broemeling <wallebroem@...il.com>

Samsung Galaxy Core Prime, Grand Prime and Ace 4 are phones based on
MSM8916. They are similar to the other Samsung devices based on MSM8916
with only a few minor differences.

This initial commit adds support for:
 - fortuna3g (SM-G530H)
 - fortunaltezt (SM-G530Y)
 - gprimeltecan (SM-G530W)
 - grandprimelte (SM-G530FZ)
 - heatqlte (SM-G357FZ)
 - rossa (SM-G360G)

The device trees contain initial support with:
 - GPIO keys
 - Regulator haptic
 - SDHCI (internal and external storage)
 - USB Device Mode
 - UART (on USB connector via the SM5502/SM5504 MUIC)
 - WCNSS (WiFi/BT)
 - Regulators

There are different variants of Grand Prime, with some differences
in accelerometer, NFC and panel.
Core Prime and Grand Prime are similar, with some differences in MUIC,
panel and touchscreen.
Ace 4 and Core Prime are similar, with some differences in panel and
touchscreen.

The common parts are shared in
msm8916-samsung-fortuna-common.dtsi and msm8916-samsung-rossa-common.dtsi
to reduce duplication.

Unfortunately, SM-G357FZ and SM-G530Y were released with outdated 32-bit
only firmware and never received any update from Samsung. Since the 32-bit
TrustZone firmware is signed there seems to be no way currently to
actually boot this device tree on arm64 Linux at the moment.

However, it is possible to use this device tree by compiling an ARM32
kernel instead. The device tree can be easily built on ARM32 with
an #include and it works really well there. To avoid confusion for others
it is still better to add this device tree on arm64. Otherwise it's easy
to forget to update this one when making some changes that affect all
MSM8916 devices.

Maybe someone finds a way to boot ARM64 Linux on this device at some
point. In this case I expect that this device tree can be simply used
as-is.
