This patchset adds support for the mpss found in the QDU1000 and QRU1000 SoCs. The mpss boot process now supports late attach for an already running mpss. For this, it uses an RMB register space to perform a handshake with the mpss for the late attach process. This is implemented in the patches below. The patches also address issues with split binary detection to support loading of split binaries more robustly. Changes from v2: * Collected Acked-by tag * Listed the items in reg property in qdu1000-mpss-pas bindings * Marked memory-region as required property * Moved rmb register logic to pas driver * Moved the logic to signal Q6 to continute booting into a helper function * Link to v2: https://lore.kernel.org/linux-arm-msm/20230306231202.12223-1-quic_molvera@xxxxxxxxxxx/ Changes from v1: * Dropped changes to aoss-qmp * Renamed mpss pas bindings * Updated commit msg on mdt loader to be more descriptive * Fixed syntax errors in bindings * Updated firmware name in bindings Komal Bajaj (1): remoteproc: qcom_q6v5_pas: Add QDU1000/QRU1000 mpss compatible Melody Olvera (3): dt-bindings: remoteproc: mpss: Document QDU1000/QRU1000 mpss devices remoteproc: qcom: q6v5: Add support for q6 rmb registers remoteproc: qcom_q6v5_pas: Add support to attach a DSP .../remoteproc/qcom,qdu1000-mpss-pas.yaml | 129 ++++++++++++++++++ drivers/remoteproc/qcom_q6v5.h | 8 ++ drivers/remoteproc/qcom_q6v5_pas.c | 107 +++++++++++++++ 3 files changed, 244 insertions(+) create mode 100644 Documentation/devicetree/bindings/remoteproc/qcom,qdu1000-mpss-pas.yaml -- 2.42.0
