From 6f84b26b53afa207092a8906fa08f4c78d65afb6 Mon Sep 17 00:00:00 2001 From: Boris Brezillon Date: Wed, 22 Nov 2017 02:38:21 +0900 Subject: mtd: nand: Add a few more timings to nand_sdr_timings Add the tR_max, tBERS_max, tPROG_max and tCCS_min timings to the nand_sdr_timings struct. Assign default/safe values for the statically defined timings, and extract them from the ONFI parameter table if the NAND is ONFI compliant.
