Hi !
I noticed that nothing in tree calls spi_set_cs_timing()
Did I miss some subtle macro trick defeating my grep ? Or is no driver
putting any requirements on CS# assertion/release and delay between
them ?
For example, the Spansion flash I'm looking at (S25FL128S) has a tCS
(delay between commands basically) of 50ns for program or erase
commands, which is quite significant.
Do we do anything to ensure this isn't violated ?
Cheers,
Ben.
