[PATCH v5 00/10] arm64: dts: qcom: lemans-evk: Extend board support for additional peripherals

From: Wasim Nazir <hidden>
Date: 2025-09-16 10:47:05
Also in: linux-arm-msm, linux-devicetree, linux-i2c, linux-mmc, lkml

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.
- Link to v4: [2]

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

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 (local)

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 (local)

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 (local)
