[PATCH v6 00/10] arm64: dts: qcom: lemans-evk: Extend board support for additional peripherals

This series extend support for additional peripherals on the Qualcomm
Lemans EVK board to enhance overall hardware functionality.

It includes:
  - New peripherals like:
    - I2C based devices like GPIO I/O expander and EEPROM.
    - GPI (Generic Peripheral Interface) DMA controllers and QUPv3 controllers
      for peripheral communication.
    - PCIe HW with required regulators and PHYs.
    - Remoteproc subsystems for supported DSPs.
    - Iris video codec.
    - First USB controller in device mode.
    - SD card support on SDHC v5.
    - Qca8081 2.5G Ethernet PHY.

Dependency:
  - The ethernet PHY QCA8081 depends on CONFIG_QCA808X_PHY, without
    which ethernet will not work.

Changes in v5:
- Dropping these changes from the series, as they are already part of
  linux-next:
  - Audio change [1]
  - MMC dt-bindings change 01/14 (v4)
  - EEPROM dt-bindings change 05/14 (v4)
- Change bias to 'pull-up' for PCIe 'perst-pins' - Konrad.

[2] https://lore.kernel.org/r/20250908-lemans-evk-bu-v4-0-5c319c696a7d@oss.qualcomm.com

Changes in v4:
- Move 'bus-width' property of SDHC to Board DT and also keep the width
  to 4 bits - Dmitry/Konrad.
- Update commit text of eeprom bindings to describe the reason for the
  change 05/14 (v3) - Dmitry.

- Link to v3: https://lore.kernel.org/r/20250904-lemans-evk-bu-v3-0-8bbaac1f25e8@oss.qualcomm.com

Changes in v3:
- Re-order QUP patch 05/13 (v2) to not break i2c node enablement in patch
  03/13 (v2) - Dmitry.
- Update commit text for QUP patch to highlight which all clients each
  QUP is accessing.
- Add dedicated compatible for Giantec EEPROM, because usage of generic
  compatible "atmel,24c256" alone is not advised.
- Update commit text for EEPROM patch 04/13 (v2) to emphasize on EEPROM
  enablement - Konrad.
- Put 'reg' property after 'compatible' in Expander - Konrad.
- Put 'pinctrl-names' after 'pinctrl-n' in PCIe - Konrad.
- SDHC:
    - Update interconnect nodes with ICC_TAG macro - Konrad.
    - Put new lines for each entry in interrupt-names, clock-names,
      interconnect-names - Konrad.
    - Put bias properties below drive-strength for consistency in
      sdc-default-state - Konrad.
    - Move 'bus-width' property to SOC DT - Konrad.
    - Move 'no-mmc' and 'no-sdio' properties to board DT - Dmitry/Konrad.
- Add 'Reviewed-by' tag from Konrad [3] on Audio patch 13/13 (v2),
  although the commit text is changed now.
- Link to v2: [4]

[4] https://lore.kernel.org/r/20250903-lemans-evk-bu-v2-0-bfa381bf8ba2@oss.qualcomm.com

Changes in v2:
- Split the patch 3/5 in v1 into separate patch per author - Bjorn.
- Use generic node names for expander - Krzysztof.
- Change video firmware to 16MB comapatible - Dmitry.
- SDHC:
    - Arrange SDHCI-compatible alphanumerically - Dmitry.
    - Move OPP table and power-domains to lemans.dtsi as these are
      part of SoC.
    - Move bus-width to board file - Dmitry.
    - Change 'states' property to array in vreg_sdc and also re-arrange
      the other properties.
- Remove the redundant snps,ps-speed property from the ethernet node as
  the MAC is actually relying on PCS auto-negotiation to set its speed
  (via ethqos_configure_sgmii called as part of mac_link_up).
- Refine commit text for audio patch - Bjorn.
- Link to v1: https://lore.kernel.org/r/20250826-lemans-evk-bu-v1-0-08016e0d3ce5@oss.qualcomm.com

Introduce the SDHC v5 controller node for the Lemans platform.
This controller supports either eMMC or SD-card, but only one
can be active at a time. SD-card is the preferred configuration
on Lemans targets, so describe this controller.

Define the SDC interface pins including clk, cmd, and data lines
to enable proper communication with the SDHC controller.

From: Krishna Kurapati <redacted>

Enable the first USB controller in device mode on the Lemans EVK
board and configure the associated LDO regulators to power
the PHYs accordingly.

The USB port is a Type-C port controlled by HD3SS3320 port controller.
The role switch notifications would need to be routed to glue driver by
adding an appropriate usb-c-connector node in DT. However in the design,
the vbus supply that is to be provided to connected peripherals when
port is configured as an DFP, is controlled by a GPIO.

There is also one ID line going from Port controller chip to GPIO-50 of
the SoC. As per the datasheet of HD3SS3320:

"Upon detecting a UFP device, HD3SS3220 will keep ID pin high if VBUS is
not at VSafe0V. Once VBUS is at VSafe0V, the HD3SS3220 will assert ID
pin low. This is done to enforce Type-C requirement that VBUS must be
at VSafe0V before re-enabling VBUS."

The current HD3SS3220 driver doesn't have this functionality present. So,
putting the first USB controller in device mode for now. Once the vbus
control based on ID pin is implemented in hd3ss3220.c, the
usb-c-connector will be implemented and dr mode would be made OTG.

interfaces (qupv3_id_0, qupv3_id_2) in the device tree to support
DMA and peripheral communication on the Lemans EVK platform.

qupv3_id_0 is used for I2C, SPI, UART, and slots 0 to 5.
qupv3_id_2 is used for I2C, SPI, UART, and slots 14 to 20.

Don't rush sending the next iteration until the discussions have been

This series extend support for additional peripherals on the Qualcomm
Lemans EVK board to enhance overall hardware functionality.

It includes:
  - New peripherals like:
    - I2C based devices like GPIO I/O expander and EEPROM.
    - GPI (Generic Peripheral Interface) DMA controllers and QUPv3 controllers
      for peripheral communication.
    - PCIe HW with required regulators and PHYs.
    - Remoteproc subsystems for supported DSPs.
    - Iris video codec.
    - First USB controller in device mode.
    - SD card support on SDHC v5.
    - Qca8081 2.5G Ethernet PHY.

Dependency:
  - The ethernet PHY QCA8081 depends on CONFIG_QCA808X_PHY, without
    which ethernet will not work.

Changes in v6:
- Update commit message of patch 02/10 (v5) to reflect QUP interfaces and
  its ports - Dmitry.
- Link to v5: https://lore.kernel.org/r/20250916-lemans-evk-bu-v5-0-53d7d206669d@oss.qualcomm.com

Changes in v5:
- Dropping these changes from the series, as they are already part of
  linux-next:
  - Audio change [1]
  - MMC dt-bindings change 01/14 (v4)
  - EEPROM dt-bindings change 05/14 (v4)
- Change bias to 'pull-up' for PCIe 'perst-pins' - Konrad.
- Link to v4: [2]

[2] https://lore.kernel.org/r/20250908-lemans-evk-bu-v4-0-5c319c696a7d@oss.qualcomm.com

Changes in v4:
- Move 'bus-width' property of SDHC to Board DT and also keep the width
  to 4 bits - Dmitry/Konrad.
- Update commit text of eeprom bindings to describe the reason for the
  change 05/14 (v3) - Dmitry.
- Bring all tags from v3.
- Link to v3: https://lore.kernel.org/r/20250904-lemans-evk-bu-v3-0-8bbaac1f25e8@oss.qualcomm.com

Changes in v3:
- Re-order QUP patch 05/13 (v2) to not break i2c node enablement in patch
  03/13 (v2) - Dmitry.
- Update commit text for QUP patch to highlight which all clients each
  QUP is accessing.
- Add dedicated compatible for Giantec EEPROM, because usage of generic
  compatible "atmel,24c256" alone is not advised.
- Update commit text for EEPROM patch 04/13 (v2) to emphasize on EEPROM
  enablement - Konrad.
- Put 'reg' property after 'compatible' in Expander - Konrad.
- Put 'pinctrl-names' after 'pinctrl-n' in PCIe - Konrad.
- SDHC:
    - Update interconnect nodes with ICC_TAG macro - Konrad.
    - Put new lines for each entry in interrupt-names, clock-names,
      interconnect-names - Konrad.
    - Put bias properties below drive-strength for consistency in
      sdc-default-state - Konrad.
    - Move 'bus-width' property to SOC DT - Konrad.
    - Move 'no-mmc' and 'no-sdio' properties to board DT - Dmitry/Konrad.
- Add 'Reviewed-by' tag from Konrad [3] on Audio patch 13/13 (v2),
  although the commit text is changed now.
- Link to v2: [4]

[4] https://lore.kernel.org/r/20250903-lemans-evk-bu-v2-0-bfa381bf8ba2@oss.qualcomm.com

Changes in v2:
- Split the patch 3/5 in v1 into separate patch per author - Bjorn.
- Use generic node names for expander - Krzysztof.
- Change video firmware to 16MB comapatible - Dmitry.
- SDHC:
    - Arrange SDHCI-compatible alphanumerically - Dmitry.
    - Move OPP table and power-domains to lemans.dtsi as these are
      part of SoC.
    - Move bus-width to board file - Dmitry.
    - Change 'states' property to array in vreg_sdc and also re-arrange
      the other properties.
- Remove the redundant snps,ps-speed property from the ethernet node as
  the MAC is actually relying on PCS auto-negotiation to set its speed
  (via ethqos_configure_sgmii called as part of mac_link_up).
- Refine commit text for audio patch - Bjorn.
- Link to v1: https://lore.kernel.org/r/20250826-lemans-evk-bu-v1-0-08016e0d3ce5@oss.qualcomm.com

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade
