[PATCH v8 0/2] arm64: dts: qcom: add dts for sa8540p-ride board

[Parikshit Pareek]

This series introduces the Qualcomm sa8540p-ride automotive development
  board, also called as Qdrive-3 board.

Changes in v8:
 - Changed the schema of the regulators(Krzysztof) 
 - Removed node remoteproc_adsp(Andrew)
 - Removed TODO comment for node usb_0_dwc3(Andrew)
 - Added Reviewed-by/Tested-by(Eric)

Changes in v7:
 - Put the smpi bus related pmic changes in sseparate dtsi files(Konrad)
 - Mention allowed regulator modes via DT property regulator-allowed-modes
   (Konrad and Brian)
 - Remove unused ldo nodes vreg_l3c and vreg_l10c(Shazad)

Changes in v6:
 - Introduced the new dts for the board, rather than moving common nodes
   between this one and SA8295 ADP board into dtsi file(Bjorn)
 - Drop 'adp' term to imply it being unrelated with ADP board(Internal
   discussion with Bjorn)
 - Removed Acked-by(Krzysztof) tag in dt-binding document, due to content
   change.
 - Not including Reviewed-by(Krzysztof), because of the content change.

Changes in v5:
 - Moved the usb and ufs nodes from sa8540p-adp.dtsi file to respective
   board specific dts files: sa8295p-adp.dts and sa8540p-adp-ride.dts.
   Took inputs from Shazad Hussain in this regard(John)
 - Added more description of the board differences(John)
 - Not including Reviewed-by for Krzysztof, because of the new changes to
   be reviewed.
 - Removed Reported-by tag(John).

Changes in v4:
- Removed the ufs_card_hc node, as it is not mounted on Qdrive-3 board.
- Removed usb_1 relared nodes, as usb1 doesn't have any port connected
   on Qdrive3 board.
- Added Reported-by tag for Shazad(for ufs and usb_1 node removals)

Changes in v3:
 - Added Acked-by tag (Krzysztof)
 - Renamed dtsi to sa8540p-adp.dtsi (John)
 - Removed copyright from sa8295-adp.dts and sa8295-adp.dtsi(John)
 - Added cover letter

Changes in v2:
 - Make dt-binding patch as the first one in the patch set
 - Add , after year 2022, in the license header

Initial version:
 - Move the common nodes to sa8540p-adp.dtsi, and create qrive-3 board
   specific file sa8540p-adp-ride.dts.

[PATCH v8 2/2] arm64: dts: qcom: add SA8540P ride(Qdrive-3)

[Parikshit Pareek]

Introduce the Qualcomm SA8540P ride automotive platform, also known as
Qdrive-3 development board.

This initial contribution supports SMP, CPUFreq, cluster idle, UFS, RPMh
regulators, debug UART, PMICs, remoteprocs and USB.

The SA8540P ride contains four PM8450 PMICs. A separate DTSI file has
been created for PMIC, so that it can be used for future SA8540P based
boards.

Why are these disabled? This should be mentioned somewhere (e.g. commit
message and/or comment) or you can drop the nodes until support is in
place.

The indentation here is off, but I noticed that you've probably just
copied that from the existing devicetree sources. I just sent a couple
of patches to clean that up:

	https://lore.kernel.org/lkml/20221116102054.4673-1-johan+linaro@kernel.org/

You can drop the first newline and indent the continuation line properly
using tabs (and spaces).
