From 7ef969a042281bdcdba31f1b69daeea4f0789ed1 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Fri, 13 Nov 2020 13:34:22 +0100 Subject: mtd: rawnand: r852: Move the ECC initialization to ->attach_chip() The probe function is only supposed to initialize the controller hardware but not the ECC engine. Indeed, we don't know anything about the NAND chip(s) at this stage. Let's move the logic initializing the ECC engine, even pretty simple, to the ->attach_chip() hook which gets called during nand_scan() routine, after the NAND chip discovery. As the previously mentioned logic is supposed to parse the DT for us, it is likely that the chip->ecc.* entries be overwritten. So let's avoid this by moving these lines to ->attach_chip().
