2020-05-31mtd: rawnand: sharpsl: Stop using nand_release()Miquel Raynal
This helper is not very useful and very often people get confused: they use nand_release() instead of nand_cleanup(). Let's stop using nand_release() by calling mtd_device_unregister() and nand_cleanup() directly.

2020-05-31mtd: rawnand: sharpsl: Fix the probe error pathMiquel Raynal
nand_release() is supposed be called after MTD device registration. Here, only nand_scan() happened, so use nand_cleanup() instead. There is no Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible. However, pointing this commit as the culprit for backporting purposes makes sense.

On error, the oxnas probe path just frees the device which failed and aborts the probe, leaving unreleased resources. Fix this situation by calling mtd_device_unregister()/nand_cleanup() on these.

2020-05-31mtd: rawnand: diskonchip: Fix the probe error pathMiquel Raynal
Not sure nand_cleanup() is the right function to call here but in any case it is not nand_release(). Indeed, even a comment says that calling nand_release() is a bit of a hack as there is no MTD device to unregister. So switch to nand_cleanup() for now and drop this comment. There is no Fixes tag applying here as the use of nand_release() in this driver predates by far the introduction of nand_cleanup() in commit d44154f969a4 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources") which makes this change possible.

2020-05-31mtd: rawnand: bcm47xx: Stop using nand_release()Miquel Raynal
This helper is not very useful and very often people get confused: they use nand_release() instead of nand_cleanup(). Let's stop using nand_release() by calling mtd_device_unregister() and nand_cleanup() directly.

2020-05-26mtd: rawnand: arasan: Support the hardware BCH ECC engineMiquel Raynal
Add support for the hardware ECC BCH engine. Please mind that this engine has an important limitation: BCH implementation does not inform the user when an uncorrectable ECC error occurs. To workaround this, we avoid using the hardware engine in the read path and do the computation with the software BCH implementation, which is faster than mixing hardware (for correction) and software (for verification).

2020-05-24mtd: rawnand: arasan: Add new Arasan NAND controllerMiquel Raynal
Add the Arasan NAND controller driver. This brings only NAND controller support. The ECC engine being a bit subtle, hardware ECC support will be added in a second time. This work is based on contributions from Naga Sureshkumar Relli.
