Revert "Revert "mtd: rawnand: gpmi: Fix setting busy timeout setting""toradex_5.4.y
This reverts commit 15a3adfe75937c9e4e0e48f0ed40dd39a0e526e2. The backport of [1] relies on having [2] also backported. Having only one of the two results in a bogus hw->timing1 setting. If only [2] is backportet the 16 bit register value likely underflows resulting in a busy_wait_timeout of 0. Or if only [1] is applied the value likely overflows with chances of having last 16 LSBs all 0 which would then result in a busy_wait_timeout of 0 too. Both cases may lead to NAND data corruption, e.g. on a Colibri iMX7 setup this has been seen. [1] commit 0fddf9ad06fd ("mtd: rawnand: gpmi: Set WAIT_FOR_READY timeout based on program/erase times") [2] commit 06781a5026350 ("mtd: rawnand: gpmi: Fix setting busy timeout setting") Upstream-Status: Submitted [https://lore.kernel.org/all/20240207174911.870822-1-max.oss.09@gmail.com/] Signed-off-by: Max Krummenacher <max.krummenacher@toradex.com>
