Having setup time 0 violates tAR, tCLR of some chips, for instance TOSHIBA TC58NVG2S3ETAI0 cannot be detected successfully (first ID byte being read duplicated, i.e. 98 98 dc 90 15 76 14 03 instead of 98 dc 90 15 76 ...).

Atmel Application Notes postulated 1 cycle NRD_SETUP without explanation [1], but it looks more appropriate to just calculate setup time properly.

Applied to mtd/fixes, thanks!

[1/1] mtd: nand: raw: atmel: Respect tAR, tCLR in read setup timing commit: fd779eac2d659668be4d3dbdac0710afd5d6db12

Patche(s) should be available on mtd/linux.git and will be part of the next PR (provided that no robot complains by then).

Kind regards, Miquèl
