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: 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 | 126 ++++++++++++++++++++++++++++++---- drivers/remoteproc/qcom_common.h | 5 +- include/linux/remoteproc/qcom_rproc.h | 34 +++++++-- 3 files changed, 146 insertions(+), 19 deletions(-)
