Boris Brezillon 50a487e771 mtd: rawnand: Pass a nand_chip object to chip->dev_ready()
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 to take
a nand_chip object instead of an mtd_info one.

We start with nand_scan().

Miquel Raynal 1ce7826d7f mtd: rawnand: mtk: convert driver to nand_scan()
Two helpers have been added to the core to do all kind of controller
side configuration/initialization between the detection phase and the
final NAND scan. Implement these hooks so that we can convert the driver
to just use nand_scan() instead of the nand_scan_ident() +
nand_scan_tail() pair.

Miquel Raynal 7da45139d2 mtd: rawnand: better name for the controller structure
In the raw NAND core, a NAND chip is described by a nand_chip structure,
while a NAND controller is described with a nand_hw_control structure
which is not very meaningful.

Rename this structure nand_controller.

As the structure gets renamed, it is logical to also rename the core
function initializing it from nand_hw_control_init() to
nand_controller_init().

Lastly, the 'hwcontrol' entry of the nand_chip structure is not
meaningful neither while it has the role of fallback when no controller
structure is provided by the driver (the controller driver is dumb and
can only control a single chip). Thus, it is renamed dummy_controller.

If driver doesn't specify parsers it can use that little helper.

Ryder Lee 36bf2eb90d mtd: rawnand: mtk: use of_device_get_match_data()
The usage of of_device_get_match_data() reduce the code size a bit.

Also, the only way to call .probe() is to match an entry in
.of_match_table[], so of_device_id cannot be NULL.

Boris Brezillon 93db446a42 mtd: nand: move raw NAND related code to the raw/ subdir
As part of the process of sharing more code between different NAND
based devices, we need to move all raw NAND related code to the raw/
subdirectory.
