qcom,hawi-cdsp-pas was initially grouped as a fallback to qcom,sm8550-cdsp-pas on the hardware-level compatibility. Bringup revealed that the NSP proxy power domain on Hawi requires a specific RPMH performance level below what sm8550 already supports, breaking the compatibility contract the fallback string implies. Remove qcom,hawi-cdsp-pas from the sm8550-cdsp-pas fallback items block, add it to the standalone compatible enum, and extend the existing cx/mxc/nsp power-domain constraint to cover it explicitly.
The fix is two-part: first, propagate the dev_pm_genpd_set_performance_state() return value so the failure becomes visible instead of silently proceeding with firmware load. Second, introduce a per-PD performance state table in qcom_pas_data so platforms can declare explicit RPMH levels for each proxy domain. Platforms that omit the table retain the existing INT_MAX behaviour. Hawi CDSP declares CX/MXC at TURBO and NSP at NOM, matching the hardware requirement. The binding and DTS are updated in tandem: qcom,hawi-cdsp-pas is made a standalone compatible (dropped from the sm8550-cdsp-pas fallback group) because the proxy PD behaviour diverges from sm8550, breaking the compatibility contract the fallback string implies. --- Changes in v3: - Converted warn into failure in 1/3 as per review. - Added R-b tag. - Link to v2: https://lore.kernel.org/lkml/[email protected]/ Changes in v2: - Propagating the err dev_pm_genpd_set_performance_state() as a separate commit. - Added a binding correction for hawi as it should be standalone one instead of falling back to sm8550. - Add num_proxy_pd_performance_states count field with a WARN_ON in probe to catch mismatch between the array size and the actual proxy PD count at boot time, returning -EINVAL if they diverge. - [v1] https://lore.kernel.org/lkml/[email protected]/ Mukesh Ojha (3): remoteproc: qcom_q6v5_pas: propagate dev_pm_genpd_set_performance_state() errors dt-bindings: remoteproc: qcom,sm8550-pas: make qcom,hawi-cdsp-pas standalone remoteproc: qcom_q6v5_pas: add per-PD proxy performance states for Hawi CDSP .../bindings/remoteproc/qcom,sm8550-pas.yaml | 3 +- drivers/remoteproc/qcom_q6v5_pas.c | 54 ++++++++++++++++++- 2 files changed, 55 insertions(+), 2 deletions(-) -- 2.55.0
