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).

The old driver was indifferently waiting a huge amount of time no matter how long the chip is supposed to stay busy for a specific operation. Here we're using the value exposed by the chip itself, and it's not a typical value, it's a max value, which means you should never reach that in real life, and if you do that means your chip is stuck for some reasons. Now, if you want to take extra safety margin, you can multiply the value by 2 and that should be enough, but 200ms is way too long. Regards, Boris

Converting the times to micro-seconds leaves us with delays that are far too short. The old pxa3xx driver had hard coded 200ms delays.
