Merge tag 'nand/for-4.13' into MTD
From Boris: """ This pull request contains the following core changes: * addition of on-ecc support to Micron driver * addition of helpers to help drivers choose most appropriate ECC settings * deletion of dead-code (cached programming and ->errstat() hook) * make sure drivers that do not support the SET/GET FEATURES command return ENOTSUPP use a dummy ->set/get_features implementation returning -ENOTSUPP (required for Micron on-die ECC) * change the semantic of ecc->write_page() for drivers setting the NAND_ECC_CUSTOM_PAGE_ACCESS flag * support exiting 'GET STATUS' command in default ->cmdfunc() implementations * change the prototype of ->setup_data_interface() A bunch of driver related changes: * various cleanup, fixes and improvements of the MTK driver * OMAP DT bindings fixes * support for ->setup_data_interface() in the fsmc driver * support for imx7 in the gpmi driver * finalization of the denali driver rework (thanks to Masahiro for the work he's done on this driver) * fix "bitflips in erased pages" handling in the ifc driver * addition of PM ops and dynamic timing configuration to the atmel driver And as usual we also have a few minor cleanup/fixes/improvements patches across the subsystem.
