This set of patches gives kernel client drivers the ability to register for a particular remoteproc's SSR notifications. 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
