MTD subsystem may return -EPROBE_DEFER if something isn't ready yet. It's important to pass that error up so device will get probed later. Signed-off-by:

ECC properties 'nand-ecc-strength' and 'nand-ecc-step-size' depends on each other, so they must be both either set or not set. In first case ECC core will try to use these values if possible (by checking ECC caps provided by driver), in second case ECC core will select most optimal values for both properties. Signed-off-by:

Binding files should be dual licensed. This file was initially written as a .txt file with no specific license, so was implicitely GPLv2. Significant part of this file and its conversion into yaml were written by Bootlin employees which agree to comply with the rules regarding the dual licensing so let's fix the SPDX tag to reflect the correct license by changing it from GPL to GPL + BSD-2-Clause.

Add support for the AC5/AC5X SoC from Marvell. The NFC on this SoC only supports SDR modes up to 3. Marvell's SDK includes some predefined values for the ndtr registers. These haven't been incorporated as the existing code seems to get good values based on measurements taken with an oscilloscope. Signed-off-by:

brcmnand controller can only access the flash spare area up to certain bytes based on the ECC level. It can be less than the actual flash spare area size. For example, for many NAND chip supporting ECC BCH-8, it has 226 bytes spare area. But controller can only uses 218 bytes. So brcmand driver overrides the mtd oobsize with the controller's accessible spare area size. When the nand base driver utilizes the nand_device object, it resets the oobsize back to the actual flash spare aprea size from nand_memory_organization structure and controller may not able to access all the oob area as mtd advises. This change fixes the issue by overriding the oobsize in the nand_memory_organization structure to the controller's accessible spare area size.

When the oob buffer length is not in multiple of words, the oob write function does out-of-bounds read on the oob source buffer at the last iteration. Fix that by always checking length limit on the oob buffer read and fill with 0xff when reaching the end of the buffer to the oob registers.

We just sorted the entries and fields last release, so just out of a perverse sense of curiosity, I decided to see if we can keep things ordered for even just one release. The answer is "No. No we cannot". I suggest that all kernel developers will need weekly training sessions, involving a lot of Big Bird and Sesame Street. And at the yearly maintainer summit, we will all sing the alphabet song together. I doubt I will keep doing this. At some point "perverse sense of curiosity" turns into just a cold dark place filled with sadness and despair. Repeats: 80e62bc8 ("MAINTAINERS: re-sort all entries and fields") Signed-off-by:

Pull x86 fix from Thomas Gleixner: "A single fix for the mechanism to park CPUs with an INIT IPI. On shutdown or kexec, the kernel tries to park the non-boot CPUs with an INIT IPI. But the same code path is also used by the crash utility. If the CPU which panics is not the boot CPU then it sends an INIT IPI to the boot CPU which resets the machine. Prevent this by validating that the CPU which runs the stop mechanism is the boot CPU. If not, leave the other CPUs in HLT" * tag 'x86-core-2023-07-09' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: x86/smp: Don't send INIT to boot CPU
