H A D | fsi-master.h | a2e7da86 Tue May 29 00:01:07 CDT 2018 Benjamin Herrenschmidt <benh@kernel.crashing.org> fsi: Add mechanism to set the tSendDelay and tEchoDelay values
Those values control the amount of "dummy" clocks between commands and between a command and its response.
This adds a way to configure them from sysfs (to be later extended to defaults in the device-tree). The default remains 16 (the HW default).
This is only supported if the backend supports the new link_config() callback to configure the generation of those delays.
