Merge tag 'nand/for-4.15' of git://git.infradead.org/l2-mtd
From Boris:
"
Core changes:
* Add a flag to mark NANDs that require 3 address cycles to encode a
page address
* Set a default ECC/free layout when NAND_ECC_NONE is requested
* Fix a bug in panic_nand_write()
Driver changes:
* Another batch of cleanups for the denali driver
* Fix PM support in the atmel driver
* Remove support for platform data in the omap driver
* Fix subpage write in the omap driver
* Fix irq handling in the mtk driver
* Change link order of mtk_ecc and mtk_nand drivers to speed up boot
time
* Change log level of ECC error messages in the mxc driver
* Patch the pxa3xx driver to support Armada 8k platforms
* Add BAM DMA support to the qcom driver
* Convert gpio-nand to the GPIO desc API
* Fix ECC handling in the mt29f driver
