Also the notifications are extended to before/after-powerup/shutdown stages. It also fixes the bug where clients need to register for notifications again if the platform driver is removed. This is done by creating a global list of per-remoteproc notification info data structures which remain static. An API is exported to register for a remoteproc's SSR notifications and uses remoteproc's ssr_name and notifier block as arguments. Changelog: v5 -> v4: - Make qcom_ssr_get_subsys static function - Fix mutex locking - Fix function comments v4 -> v3: - Fix naming convention v3 -> v2: - Create a global list of per remoteproc notification data structure - Pass ssr_name and crashed information as part of notification data - Move notification type enum to qcom_rproc.h from remoteproc.h v2 -> v1: - Fix commit text Rishabh Bhatnagar (1): remoteproc: qcom: Add per subsystem SSR notification Siddharth Gupta (1): remoteproc: qcom: Add notification types to SSR drivers/remoteproc/qcom_common.c | 128 ++++++++++++++++++++++++++++++---- drivers/remoteproc/qcom_common.h | 5 +- include/linux/remoteproc/qcom_rproc.h | 36 ++++++++-- 3 files changed, 149 insertions(+), 20 deletions(-) -- The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum, a Linux Foundation Collaborative Project
