[PATCH v9 0/1] arm64: dts: qcom: add initial support for Samsung Galaxy S22

[Eric Gonçalves]

Changes in v9:
- Change 'vph-pwr-regulator' to 'regulator-vph-pwr'

Changes in v8:
- Rebase on 'arm64: dts: qcom: sm8450: Flatten usb controller node'
- Use real name for sign-offs
- Remove device tree binding patch as it's already in the tree, merged by
 Bjorn

Changes in v7:
- Document the reserved GPIO pins, remove pin 50 as it does not
 need to be reserved
- Clarify the phone isn't limited to USB 2.0 but rather USB 3.0
 isn't implemented yet
- Add a newline before every 'status' node

Changes in v6:
- Remove debug features (bootargs, etc) that slipped in the v5 DTS
- Format and organize nodes correctly based on existing DTS, 
 move "status = "okay";" to the bottom always
- Solve "ddr_device_type" and "qcom,rmtfs-mem" warnings, the rest are
 from existing SoC .dtsi
- Disable buttons, ufs and other features for later revision

Changes in v5:
- Properly format the thread

Changes in v4:
- Try to properly format the thread

Changes in v3:
- Removed unnecessary initrd start and end addresses
- Make sure r0q is in right order on Makefile
- Properly format memory addresses
- Set r0q to the correct, alphabetical order in documents

Changes in v2:
- Attempt to format the patchset thread correctly
