Once a page is read with higher bitflips all subsequent reads are returning the same bitflip value even though they have none. max_bitflip variable is not being reset to 0 across page reads. This is causing problems like incorrectly marking erase blocks bad by UBI and causing read failures. Verified the change with both MTD reads and UBI. This change is inline with other NFC drivers. Sample error log where a block is marked bad incorrectly: ubi0: fixable bit-flip detected at PEB 125 ubi0: run torture test for PEB 125 ubi0: fixable bit-flip detected at PEB 125 ubi0 error: torture_peb: read problems on freshly erased PEB 125, must be bad ubi0 error: erase_worker: failed to erase PEB 125, error -5 ubi0: mark PEB 125 as bad Link: https://lore.kernel.org/all/ea0422cd-a8e6-3c36-f551-a0142893301b@marvell.com Signed-off-by: rminnikanti <rminnikanti@marvell.com> Reviewed-by: Chris Packham <judge.packham@gmail.com> Signed-off-by: rminnikanti <rminnikanti@marvell.com> Acked-by: Michael Trimarchi <michael@amarulasolutions.com> Signed-off-by: Dario Binacchi <dario.binacchi@amarulasolutions.com>

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay Ethernet"' I failed to notice that b4 noticed it was based on next and so took that as the base commit and merged that part of next to master. This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Michal Simek <michal.simek@amd.com> says: I looked as cleaning up some dependencies and I found that qconfig is reporting some issues. This series is fixing some of them. But there are still some other pending. That's why please go and fix them if they are related to your board. UTF-8: I am using uni2ascii -B < file to do conversion. When you run it in a loop you will find some other issue with copyright chars or some issues in files taken from the Linux kernel like DTs. They should be likely fixed in the kernel first. Based on discussion I am ignoring names too.
Convert UTF-8 chars to ASCII in cases where make sense. No Copyright or names are converted. Signed-off-by: Michal Simek <michal.simek@amd.com> Reviewed-by: Tom Rini <trini@konsulko.com> Acked-by: Marek Behún <kabel@kernel.org>

The first patch is by Weizhao Ouyang and avoids sf probe crashes. The second patch is by Arseniy Krasnov and adds basic support for Amlogic Meson NAND controller on AXG. The following four patches are by Alexander Dahl and apply some fixes to drivers/mtd/nand/raw/ and port some changes applied in Linux. The following patch is by Bruce Suen and adds support for XTX SPINAND. Finally, the last patch is again by Arseniy Krasnov and adds access to OTP region, supporting info, dump, write and lock operations.
