[PATCH v4 00/14] arm64: dts: qcom: lemans-evk: Extend board support for additional peripherals

[Wasim Nazir]

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.
  - Audio change [1] to support capture and playback on I2S.

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

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 [2] on Audio patch 13/13 (v2),
  although the commit text is changed now.
- Link to v2: [3]

[2] https://lore.kernel.org/linux-arm-msm/b4b6678b-46dd-4f57-9c26-ff0e4108bf79@oss.qualcomm.com/
[3] 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

[PATCH v4 01/14] dt-bindings: mmc: sdhci-msm: Document the Lemans compatible

[Wasim Nazir]

From: Monish Chunara <quic_mchunara@quicinc.com>

Add the MSM SDHCI compatible name to support both eMMC and SD card for
Lemans, which uses 'sa8775p' as the fallback SoC. Ensure the new
compatible string matches existing Lemans-compatible formats without
introducing a new naming convention.

The SDHCI controller on Lemans is based on MSM SDHCI v5 IP. Hence,
document the compatible with "qcom,sdhci-msm-v5" as the fallback.

Hi Ulf,

Could you please pick the binding (this patch) through your tree, so that the DT
Maintainer can pick up the remaining dts changes through the qcom tree?

Sure, I usually do that, but sorry for the delay!

Applied for next, thanks!

[PATCH v4 02/14] arm64: dts: qcom: lemans: Add SDHC controller and SDC pin configuration

[Wasim Nazir]

From: Monish Chunara <quic_mchunara@quicinc.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.

DMA and peripheral communication on the Lemans EVK platform.

qupv3_id_0 provides access to I2C/SPI/UART instances 0-5.
qupv3_id_2 provides access to I2C/SPI/UART instances 14-20.

[PATCH v4 05/14] dt-bindings: eeprom: at24: Add compatible for Giantec GT24C256C

[Wasim Nazir]

The gt24c256c is another 24c256 compatible EEPROM, and does not
follow the generic name matching, so add a separate compatible for it.
This ensures accurate device-tree representation and enables proper
kernel support for systems using this part.

[PATCH v4 06/14] arm64: dts: qcom: lemans-evk: Add EEPROM and nvmem layout

[Wasim Nazir]

From: Monish Chunara <quic_mchunara@quicinc.com>

Integrate the GT24C256C EEPROM via I2C to enable access to
board-specific non-volatile data.

Also, define an nvmem-layout to expose structured regions within the
EEPROM, allowing consumers to retrieve configuration data such as
Ethernet MAC addresses via the nvmem subsystem.

Ack, we should do pull up.
we took reference from the previous targets which seems to be wrong.
we will make it pull up.

[PATCH v4 10/14] arm64: dts: qcom: lemans-evk: Enable first USB controller in device mode

[Wasim Nazir]

From: Krishna Kurapati <krishna.kurapati@oss.qualcomm.com>

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.

[PATCH v4 14/14] arm64: dts: qcom: lemans-evk: Add sound card

[Wasim Nazir]

From: Mohammad Rafi Shaik <mohammad.rafi.shaik@oss.qualcomm.com>

Add the sound card for Lemans-Evk board and verified playback
functionality using the max98357a I2S speaker amplifier and I2S
microphones. The max98357a speaker amplifier is connected via
High-Speed MI2S HS0 interface, while the microphones utilize the
HS2 interface. This patch also introduces pin control support
for the High-Speed I2S interfaces.
