interconnect: qcom: sdx75: Drop QPIC interconnect and BCM nodes

2026-01-08T09:14:30+00:00

commit 295f58fdccd05b2d6da1f4a4f81952ccb565c4dc upstream.

As like other SDX SoCs, SDX75 SoC's QPIC BCM resource was modeled as a
RPMh clock in clk-rpmh driver. However, for SDX75, this resource was also
described as an interconnect and BCM node mistakenly. It is incorrect to
describe the same resource in two different providers, as it will lead to
votes from clients overriding each other.

Hence, drop the QPIC interconnect and BCM nodes and let the clients use
clk-rpmh driver to vote for this resource.

Without this change, the NAND driver fails to probe on SDX75, as the
interconnect sync state disables the QPIC nodes as there were no clients
voting for this ICC resource. However, the NAND driver had already voted
for this BCM resource through the clk-rpmh driver. Since both votes come
from Linux, RPMh was unable to distinguish between these two and ends up
disabling the QPIC resource during sync state.

>From the initial submission the interconnect driver missed the link from
SNOC_PNOC to the USB 2 configuration space. Add missing link in order to
let the platform configure and utilize this path.

interconnect: qcom: icc-rpmh: probe defer incase of missing QoS clock dependency

Return -EPROBE_DEFER from interconnect provider incase probe defer is
received from devm_clk_bulk_get_all(). This would help in reattempting
the inteconnect driver probe, once the required QoS clocks are
available.
