A terminate resets the slave's state machines 26a7ec9371SChristopher Bostic that control access to the internally connected engines. In 27a7ec9371SChristopher Bostic addition the slave freezes its internal error register for 28a7ec9371SChristopher Bostic debugging purposes. This command is also needed to abort any 29a7ec9371SChristopher Bostic ongoing operation in case of an expired 'Master Time Out' 30a7ec9371SChristopher Bostic timer. 31a7ec9371SChristopher Bostic 322fc95e04SJoel StanleyWhat: /sys/bus/platform/devices/../fsi-master/fsi0/slave@00:00/raw 33a7ec9371SChristopher BosticDate: May 2017 34a7ec9371SChristopher BosticKernelVersion: 4.12 352fc95e04SJoel StanleyContact: linux-fsi@lists.ozlabs.org 36a7ec9371SChristopher BosticDescription: 37a7ec9371SChristopher Bostic Provides a means of reading/writing a 32 bit value from/to a 38a7ec9371SChristopher Bostic specified FSI bus address. 394a851d71SJoel Stanley 404a851d71SJoel StanleyWhat: /sys/bus/platform/devices/../cfam_reset 414a851d71SJoel StanleyDate: Sept 2020 424a851d71SJoel StanleyKernelVersion: 5.10 434a851d71SJoel StanleyContact: linux-fsi@lists.ozlabs.org 444a851d71SJoel StanleyDescription: 454a851d71SJoel Stanley Provides a means of resetting the cfam that is attached to the 464a851d71SJoel Stanley FSI device. 47
