Revert commit c70f7dcd0921 ("interconnect: qcom: x1e80100: enable QoS
configuration") because it breaks the ABI without justification what was
broken and what was not working. It claims the clocks are needed for
QoS, which might be correct, but QoS itself is not a mandatory thing for
the device to operate.
Fixes: c70f7dcd0921 ("interconnect: qcom: x1e80100: enable QoS configuration")
Closes: https://krzk.eu/#/builders/102/builds/70/steps/23/logs/warnings__3_

Revert commit c83cf1b1c6f1 ("dt-bindings: interconnect:
qcom,x1e80100-rpmh: add clocks property to enable QoS") because it
breaks the ABI without justification what was broken and what was not
working. It claims the clocks are needed for QoS, which might be
correct, but QoS itself is not a mandatory thing for the device to
operate.
Fixes: c83cf1b1c6f1 ("dt-bindings: interconnect: qcom,x1e80100-rpmh: add clocks property to enable QoS")

Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
Pre-existing issues:
- [High] Returning directly on `-EPROBE_DEFER` during QoS clock initialization bypasses node cleanup, leaking nodes and causing a Use-After-Free on probe retry.

commit dc792c2aa6455fa0377849e9d95a326611b7bb15
Author: Krzysztof Kozlowski <krzysztof.kozlowski@oss.qualcomm.com>
interconnect: qcom: x1e80100: Revert ABI break
This patch reverts the enablement of QoS configuration for the x1e80100
interconnect driver. It removes the QoS box definitions and the requirement
for QoS clocks, as QoS is not mandatory for the device to operate.

[Severity: High]
This is a pre-existing issue, but it looks like reverting the
qos_requires_clocks flag here might be masking a severe structural flaw
in qcom_icc_rpmh_probe() that triggers a use-after-free on probe retry.
In qcom_icc_rpmh_probe(), interconnect nodes are created via
icc_node_create_dyn() and added to the provider, with their pointers stored
in the driver's statically allocated qnodes definitions (qn->node).
If the subsequent call to devm_clk_bulk_get_all() returns -EPROBE_DEFER
(which only happens when qos_requires_clocks is true), the function
executes return dev_err_probe(...) and returns immediately. This completely
bypasses the err_remove_nodes cleanup path which calls icc_nodes_remove().
Because of this bypass:
1. The provider struct is freed by devres, but the nodes remain registered
globally in icc_idr with a dangling node->provider pointer.
2. On probe retry, the driver sees qn->node is already non-NULL and reuses
the old node.
3. The subsequent icc_node_add() hits WARN_ON(node->provider) (since it
points to the freed provider) and returns early without updating the pointer.
4. Any later interconnect operation (like qcom_icc_set()) dereferences the
dangling node->provider, leading to a guaranteed use-after-free.
Does this framework bug explain why enabling the clocks broke the ABI and
caused warnings?

Pre-existing issue, I'll fix it.

Would a saner resolution not be to simply adjust the bindings change to
mimic the other post-factum QoS clock additions, where `required:`
wasn't altered?
e.g.
e07f3b8c9e1c ("dt-bindings: interconnect: qcom,qcs615-rpmh: add clocks property to enable QoS")

Maybe saner but I am really annoyed with the fact that authors don't
care about dtbs_check rules and impact on users.
Anyway, commits were dropped, so this patchset can be ignored.
Best regards,
