Browse code Tegra210: suspend/resume bpmp interface across System Suspend The BPMP firmware takes some time to initialise its state on exiting System Suspend state. The CPU needs to synchronize with the BPMP during this process to avoid any race conditions. This patch suspends and resumes the BPMP interface across a System Suspend cycle, to fix this race.
