mtd: nand: Fix NAND_USE_BOUNCE_BUFFER flag conflict

2015-07-07T20:03:25+00:00

Commit 66507c7bc8895f0da6b ("mtd: nand: Add support to use nand_base
poi databuf as bounce buffer") added a flag NAND_USE_BOUNCE_BUFFER
using the same bit value as the existing NAND_BUSWIDTH_AUTO.

mtd: nand: add common DT init code

2015-05-11T23:22:29+00:00

These are already-documented common bindings for NAND chips. Let's
handle them in nand_base.

If NAND controller drivers need to act on this data before bringing up
the NAND chip (e.g., fill out ECC callback functions, change HW modes,
etc.), then they can do so between calling nand_scan_ident() and
nand_scan_tail().

mtd: nand_bbt: make nand_scan_bbt() static

This implementation detail is no longer needed outside of nand_bbt.c.

mtd: nand: provide detailed description for raw read/write page methods

2014-11-20T08:02:46+00:00

read_page_raw and write_page_raw method description is not clear enough.
It clearly specifies that ECC correction should not be involved but does
not talk about specific layout (by layout I mean where in-band and
out-of-band data are stored on the NAND media) used by NAND/ECC
controllers.

Those specific layouts might impact MTD users and thus should be hidden (as
already done in the standard NAND_ECC_HW_SYNDROME implementation).

Clearly state this constraint in the nand_ecc_ctrl struct documentation.

mtd: nand: support ONFI timing mode retrieval for non-ONFI NANDs

2014-09-22T18:29:57+00:00

Add an onfi_timing_mode_default field to nand_chip and nand_flash_dev in
order to support NAND timings definition for non-ONFI NAND.

NAND that support better timings mode than the default one have to define
a new entry in the nand_ids table.

The default timing mode should be deduced from timings description from
the datasheet and the ONFI specification
(www.onfi.org/~/media/ONFI/specs/onfi_3_1_spec.pdf, chapter 4.15
"Timing Parameters").
You should choose the closest mode that fit the timings requirements of
your NAND chip.

mtd: nand: fix DocBook warnings on nand_sdr_timings doc

2014-08-19T18:55:38+00:00

Change the comment type (from /** to /*) to prevent DocBook from
complaining about missing description for nand_sdr_timings fields.

There is currently no need in documenting those fields because they are
fully described in the ONFI specification (which is pointed out in the
comment).

mtd: nand: add ONFI timing mode to nand_timings converter

2014-07-22T02:39:55+00:00

Add a converter to retrieve NAND timings from an ONFI NAND timing mode.
At the moment, only SDR NAND timings are supported.
