Miquel Raynal 415ae78ffb mtd: rawnand: check ONFI timings have been acked by the chip
Choosing ONFI timings when ->set/get_features() calls are supported
by the NAND chip is a matter of reading the chip's ONFI parameter page
and telling the chip the chosen mode (between all of the supported ones)
with ->set_feature().

Add a check on whether the chip "acked" the timing mode or not.

This can be a problem for NAND chips that do not follow entirely the
ONFI specification. These chips actually support other modes than
"mode 0", but either:
1/ do not update the timing mode register once a timing mode has been
   selected.
or
2/ do not support the TIMING_MODE featured and thus do not require users
   to change the timing mode at all.

These issues will be addressed in another patch that will add the
feature to overwrite NAND chips features within the parameter page, from
the NAND chip driver.

README

Linux kernel
============

This file was moved to Documentation/admin-guide/README.rst

Please notice that there are several guides for kernel developers and users.
These guides can be rendered in a number of formats, like HTML and PDF.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
