Merge tag 'mtd/fixes-for-5.10-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux
Pull mtd fixes from Miquel Raynal: "Second series of fixes for raw NAND drivers initiated because of a rework of the ECC engine subsystem. The location of the DT parsing logic got moved, breaking several drivers which in fact were not doing the ECC engine initialization at the right place. These drivers have been fixed by enforcing a particular ECC engine type and algorithm, software Hamming, while the algorithm may be overwritten by a DT property. This merge request fixes this in the xway, socrates, plat_nand, pasemi, orion, mpc5121, gpio, au1550 and ams-delta controller drivers" * tag 'mtd/fixes-for-5.10-rc8' of git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux: mtd: rawnand: xway: Do not force a particular software ECC engine mtd: rawnand: socrates: Do not force a particular software ECC engine mtd: rawnand: plat_nand: Do not force a particular software ECC engine mtd: rawnand: pasemi: Do not force a particular software ECC engine mtd: rawnand: orion: Do not force a particular software ECC engine mtd: rawnand: mpc5121: Do not force a particular software ECC engine mtd: rawnand: gpio: Do not force a particular software ECC engine mtd: rawnand: au1550: Do not force a particular software ECC engine mtd: rawnand: ams-delta: Do not force a particular software ECC engine
