[RFC 00/12] Marvell NAND controller rework with ->exec_op()

From: Miquel Raynal
Date: Wed Oct 18 2017 - 10:36:45 EST

Hi,

This series adds the implementation of the NAND framework ->exec_op()
interface with all the related hooks and helpers. The reasons for adding
it are explained in details in the commit log "mtd: nand: add
->exec_op() implementation", but mostly it will ease later expansion of
the framework, as well as the implementation of new vendor specific
commands, and should also ease driver development.

The series contains as well the reworked NAND controller driver from
Marvell.

A lot of comments are written to explain how to use the new API and the
Marvell driver shows how to implement it. A proper external
documentation is being written and will later be submitted.

It also changes the device tree NAND node definition for all platforms
referring to the Marvell driver to use the new bindings. They are more
hierarchical and fit the real organization of the hardware, by having
NAND partitions that are part of NAND chip nodes, themselves part of
the NAND controller node.

See the commit log of "mtd: nand: add reworked Marvell NAND controller
driver" for details about why a completely new driver is needed.

As this series changes several core functions and also directly touches
multiple controller drivers, it would be great to have reviews and tests
from the concerned maintainers. Only PXA3xx SoCs are not supported yet
(explaining the RFC) as having a local board to test is really needed.

Thank you,
MiquÃl
