Enhance the Qualcomm Lemans EVK board file to support essential
peripherals and improve overall hardware capabilities, as
outlined below:
  - Enable GPI (Generic Peripheral Interface) DMA-0/1/2 and QUPv3-0/2
    controllers to facilitate DMA and peripheral communication.
  - Add support for PCIe-0/1, including required regulators and PHYs,
    to enable high-speed external device connectivity.
  - Integrate the TCA9534 I/O expander via I2C to provide 8 additional
    GPIO lines for extended I/O functionality.
  - Enable the USB0 controller in device mode to support USB peripheral
    operations.
  - Activate remoteproc subsystems for supported DSPs such as Audio DSP,
    Compute DSP-0/1 and Generic DSP-0/1, along with their corresponding
    firmware.
  - Configure nvmem-layout on the I2C EEPROM to store data for Ethernet
    and other consumers.
  - Enable the QCA8081 2.5G Ethernet PHY on port-0 and expose the
    Ethernet MAC address via nvmem for network configuration.
    It depends on CONFIG_QCA808X_PHY to use QCA8081 PHY.
  - Add support for the Iris video decoder, including the required
    firmware, to enable video decoding capabilities.
  - Enable SD-card slot on SDHC.
I know I asked for you to lump things together in the initial
contribution to provide as much features as possible in that initial
patch, but now that is in place and this patch really is a bunch of
independent logical changes and this commit message reads much more like
a cover letter...

And I don't think you all wrote this patch, you probably all wrote
individual pieces and then one of you created the actual patch?

The important part is that we don't want 9 different patch series
floating around with unmet dependencies and relying on me to try to
stitch them together.

But if you could do what you did for patch 2, 4, and 5 for logical
chunks of this change, that would be excellent (i.e. you collect the
individual patches, you add your signed-off-by, and you send them all
together).
Sure Bjorn, I will split it in next version of the same series.
