… board DT The Monaco SoC SDHC controller supports both eMMC and SD cards. However, the 'supports-cqe' property (Command Queue Engine) is specific to eMMC and conflicts with SD card operation. Remove 'supports-cqe' from the SoC device tree to ensure compatibility with SD cards. Simultaneously, add the property explicitly to the qcs8300-ride board device tree, as this board uses the controller in eMMC mode. This ensures the SoC definition remains generic while enabling features correctly at the board level. Signed-off-by: Monish Chunara <monish.chunara@oss.qualcomm.com>
…overlay The monaco EVK board supports either eMMC or SD-card, but only one can be active at a time. Enable the SD Host Controller Interface (SDHCI) on the monaco EVK board to support SD Card for storage via a device tree overlay. This allows eMMC support to be enabled through a separate overlay when required. Signed-off-by: Monish Chunara <monish.chunara@oss.qualcomm.com>

This series enables SDHCI storage support for both SD Card and eMMC on the
Qualcomm Monaco EVK platform.
The Monaco SoC shares the SDHCI controller between SD Card and eMMC use
cases. Previously, the common SoC dtsi unconditionally enabled the
'supports-cqe' property. This causes regression for SD cards, resulting
in timeouts and initialization failures during the probe sequence, as
the driver attempts to enable Command Queueing (CQE) logic incompatible
with the SD protocol.
To resolve this and enable full storage support, this series:
Moves the 'supports-cqe' property out of the common SoC dtsi. It is
now only enabled in the specific eMMC configuration where it is
supported.
Adds a device tree overlay to enable SD Card support (SDR/DDR modes).
Adds a device tree overlay to enable eMMC support.
Validated on Qualcomm Monaco EVK with both SD Card and eMMC modules.
