When the 'keep-config' property is populated, the ->setup_data_interface() hook of the driver is not shown to the core, which leads to not "updating" the timings like tPROG_max.
While it worked with the old driver that hardcoded this delay, this might not work anymore with the current driver because it expects timings.sdr.tPROG_max to be != 0 (and PSEC_TO_MSEC(0) also returns 0).
This is probably something to fix.
