[PATCH v9 0/2] arm64: dts: qcom: add dts for sa8540p-ride board

[Parikshit Pareek]

Changes in v9:
 - Enabled ufs_mem_hc/ufs_mem_phy nodes(John)
 - Corrected the indentation of 'regulator-allowed-modes' properties.

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 v9 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.
