Hello,
This is the first set of patches aiming at cleaning the raw NAND API.
This one focuses on inconsistencies we have in the API + the nand_chip
and nand_ecc_ctrl interfaces. Some functions/hooks are passed a
nand_chip object, some are passed an mtd_info object and some are
passed both.
Since mtd_info can be extracted from nand_chip, we can simply always
pass a nand_chip and make things consistent. Hopefully with these
changes merged we'll stop seeing new drivers reproducing the same
mistake (passing both mtd_info and nand_chip or using mtd_info where
nand_chip is more appropriate).
For those who want to see what's in the pipe, here is a branch [1]
containing all the cleanups I plan to merge.
Not much has changed in this v2. I just rebased on top of nand/next,
fixed typos, added A-b/R-b tags, and that's all.
Regards,
Boris

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
In order to do that, we first need to update the platform_nand_ctrl
hooks to take a nand_chip object instead of an mtd_info.
We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip
conversion, but those will be dropped when patching nand_chip hooks to
take a nand_chip object.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
In order to do that, we first need to update the platform_nand_ctrl
hooks to take a nand_chip object instead of an mtd_info.
We add temporary plat_nand_xxx() wrappers to the do the mtd -> chip
conversion, but those will be dropped when patching nand_chip hooks to
take a nand_chip object.

We start with nand_scan().

Let's make the raw NAND API consistent by patching all helpers to take
a nand_chip object instead of an mtd_info one.
We start with nand_scan().

Let's make the raw NAND API consistent by patching all helpers to
take a nand_chip object instead of an mtd_info one.
Now is nand_release()'s turn.

* [PATCH v2 03/23] mtd: rawnand: Pass a nand_chip object to nand_release()

Let's make the raw NAND API consistent by patching all helpers to
take a nand_chip object instead of an mtd_info one.
Now is nand_release()'s turn.

Now is nand_wait_ready()'s turn.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one.
Now is ecc->hwctl()'s turn.

hooks to take a nand_chip object instead of an mtd_info one.
Now is ecc->calculate()'s turn.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one.
Now is ecc->calculate()'s turn.

Now is ecc->correct()'s turn.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->read_xxx() hooks at once.

* [PATCH v2 08/23] mtd: rawnand: Pass a nand_chip object to ecc->read_xxx() hooks

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->read_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->write_xxx() hooks at once.

* [PATCH v2 09/23] mtd: rawnand: Pass a nand_chip object to ecc->write_xxx() hooks

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all ecc->write_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->read_xxx() hooks at once.

* [PATCH v2 10/23] mtd: rawnand: Pass a nand_chip object to chip->read_xxx() hooks

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->read_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->write_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle all chip->write_xxx() hooks at once.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->select_chip() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->select_chip() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmd_ctrl() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmd_ctrl() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->dev_ready() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->dev_ready() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmdfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->cmdfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->waitfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->waitfunc() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->erase() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->{get,set}_features() hooks.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->setup_read_retry() hook.

* [PATCH v2 21/23] mtd: rawnand: Pass a nand_chip object to chip->setup_data_interface()

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the chip->setup_data_interface() hook.

Let's make the raw NAND API consistent by patching all helpers and
hooks to take a nand_chip object instead of an mtd_info one or
remove the mtd_info object when both are passed.
Let's tackle the nand_xxx_bbt() helpers.
