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 "
