scsi: pm80xx: Add sysfs attribute to track iop1 count
A new sysfs variable 'ctl_iop1_count' is being introduced that tells if the controller is alive by indicating controller ticks. If on subsequent run we see the ticks changing that indicates that controller is not dead. Using the 'ctl_iop1_count' sysfs variable we can see ticks incrementing: linux-9saw:~# cat /sys/class/scsi_host/host*/ctl_iop1_count 0x00000069 0x0000006b 0x0000006d 0x00000072 Link: https://lore.kernel.org/r/[email protected] Acked-by: Jack Wang <[email protected]> Signed-off-by: Vishakha Channapattan <[email protected]> Signed-off-by: Viswas G <[email protected]> Signed-off-by: Ruksar Devadi <[email protected]> Signed-off-by: Ashokkumar N <[email protected]> Signed-off-by: Radha Ramachandran <[email protected]> Signed-off-by: Martin K.
