The system controller's resource manager have support for configuring the TDTYPE of TCHAN_CFG register on j721e. With this parameter the teardown completion can be controlled: TDTYPE == 0: Return without waiting for peer to complete the teardown TDTYPE == 1: Wait for peer to complete the teardown Signed-off-by: Peter Ujfalusi <redacted> Reviewed-by: Tero Kristo <redacted> Tested-by: Keerthy <j-keerthy@ti.com> Reviewed-by: Grygorii Strashko <grygorii.strashko@ti.com> --- drivers/firmware/ti_sci.c | 1 + drivers/firmware/ti_sci.h | 7 +++++++ include/linux/soc/ti/ti_sci_protocol.h | 2 ++ 3 files changed, 10 insertions(+)
