soc: qcom: smem: add build infra

qcom: rpmh: don't error for SLEEP requests

2026-03-24T10:49:17Z

Just stub out non-active votes, if we return an error the caller may propagate it and not send its active vote. Since we don't suspend there's no risk of us entering a broken state due to missing votes.

soc/qcom: rpmh: correctly wait for TCS flush

2026-01-14T15:25:09Z

Several bugs were discovered in the rpmh-rsc driver which collectively meant we were never actually waiting for the TCS to flush, these were likely missed because U-Boot runs single threaded and the RPMh had typically processed the single command we sent by the time we went to send the next one. However a future patch will implement rpmh read support which requires us to properly wait for the RPMh command response so we can return the value. Fix these issues so we correctly ensure the TCS is done before returning. Link: https://patch.msgid.link/20260108-rpmh-regulator-fixes-v1-3-d1b5b300b665@linaro.org Signed-off-by: Casey Connolly
