[PATCH 0/2] Migrate the GPMI driver to use NAND core timings

[Miquel Raynal]

Hello,

The GPMI NAND controller driver has its own timings logic while the core
also has its own that should be preferred to avoid code duplication.
This series migrates the driver to use the ->setup_data_interface()
hook, preferred way to handle timings negotiation between controllers
and NAND chips.

This driver has stronger requirements in terms of respect of the ONFI
specification than the core has, and last time I post changes to this
section this was raised to me. Hence, the first patch effectively
applies the same requirements to the core. Doing this can slow down
several chips that do not follow entirely the specifications, but
another series is coming to add the possibility for NAND vendors to
flag certain features as "unsupported". See

    "mtd: nand: Check ONFI timings have been acked by the chip"

commit log for more details.

Thank you,
Miquèl
