Merge tag 'nand/for-4.17' of git://git.infradead.org/linux-mtd into mtd/next
Core changes: * Prepare arrival of the SPI NAND subsystem by implementing a generic (interface-agnostic) layer to ease manipulation of NAND devices * Move onenand code base to the drivers/mtd/nand/ dir * Rework timing mode selection * Provide a generic way for NAND chip drivers to flag a specific GET/SET FEATURE operation as supported/unsupported * Stop embedding ONFI/JEDEC param page in nand_chip Driver changes: * Rework/cleanup of the mxc driver * Various cleanups in the vf610 driver * Migrate the fsmc and vf610 to ->exec_op() * Get rid of the pxa driver (replaced by marvell_nand) * Support ->setup_data_interface() in the GPMI driver * Fix probe error path in several drivers * Remove support for unused hw_syndrome mode in sunxi_nand * Various minor improvements

-PXA3xx NAND DT bindings
-
-Required properties:
-
- - compatible: Should be set to one of the following:
- marvell,pxa3xx-nand
- marvell,armada370-nand
- marvell,armada-8k-nand
- - reg: The register base for the controller
- - interrupts: The interrupt to map
- - #address-cells: Set to <1> if the node includes partitions
- - marvell,system-controller: Set to retrieve the syscon node that handles
- NAND controller related registers (only required
- with marvell,armada-8k-nand compatible).
-
-Optional properties:
-
- - dmas: dma data channel, see dma.txt binding doc
- - marvell,nand-enable-arbiter: Set to enable the bus arbiter
- - marvell,nand-keep-config: Set to keep the NAND controller config as set
- by the bootloader
- - num-cs: Number of chipselect lines to use
- - nand-on-flash-bbt: boolean to enable on flash bbt option if
- not present false
- - nand-ecc-strength: number of bits to correct per ECC step
- - nand-ecc-step-size: number of data bytes covered by a single ECC step
-
-The following ECC strength and step size are currently supported:
-
- - nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- - nand-ecc-strength = <4>, nand-ecc-step-size = <512>
- - nand-ecc-strength = <8>, nand-ecc-step-size = <512>
-
-Example:
-
- nand0: nand@43100000 {
- compatible = "marvell,pxa3xx-nand";
- reg = <0x43100000 90>;
- interrupts = <45>;
- dmas = <&pdma 97 0>;
- dma-names = "data";
- #address-cells = <1>;
