We try to force NAND controller drivers to properly separate the NAND
controller object from the NAND chip one, so let's deprecate the dummy
controller object embedded in nand_chip to encourage them to create
their own instance.

Now that the CS line to be selected is passed to ->exec_op() and
stored in chip->cur_cs and after patching all drivers implementing
->exec_op() to stop implementing this method, we can deprecate it by
moving it to the nand_legacy structure.

The wait timeouts and delays are directly extracted from the NAND
timings and ->chip_delay is only used in legacy path, so let's move it
to the nand_legacy struct to make it clear.

We regularly have new NAND controller drivers that are making use of
fields/hooks that we want to get rid of but can't because of all the
legacy drivers that we might break if we do.
So, instead of removing those fields/hooks, let's move them to a
sub-struct which is clearly documented as deprecated.
We start with the ->IO_ADDR_{R,W] fields.

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.
Also change the unused "struct device *dev" parameter of the driver
structure into a platform device to reuse it in the ->attach_chip()
hook.

uintptr_t should be used when casting a pointer to an unsigned int so
that the code compiles without warnings even on 64-bit architectures.
This is needed if we want to allow selection of this driver when
COMPILE_TEST=y.

There is no point in doing this sort of conversion since we can
replace |= by += operations which are perfectly valid on pointers.
This is done in preparation of COMPILE_TEST addition to the NAND_DAVINCI
Kconfig entry, since building for x86 generates several warnings because
of inappropriate u32 <-> void * conversions (pointers are 64-bit large
on x86_64).

git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform updates from Olof Johansson:
"Here are the main updates for SoC support (besides DT additions) for
ARM 32- and 64-bit platforms. The branch also contains defconfig
updates to turn on drivers and options as needed on the various
platforms.
The largest parts of the delta are from cleanups moving platform data
and board file setup of TI platforms to ti-sysc bus drivers. There are
also some sweeping changes of eeprom and nand setup on Davinci, i.MX
and other platforms.
Samsung is removing support for Exynos5440, which was an oddball SoC
that hasn't been seen much use in designs.
Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D).
Linus Walleij is also removing support for ux500 (Sony Ericsson)
U8540/9540 SoCs that never made it to significant mass production and
products"

NAND itself is an asynchronous interface, it does not have any
clock input. DaVinci NAND driver acquires clock for AEMIF
(asynchronous external memory interface) which is an on-chip
IP to which NAND is connected.
The same clock is also enabled in AEMIF driver (either present
drivers/memory or from machine code for some older platforms).
AEMIF timing must be initialized before NAND can be accessed.
This ensures that AEMIF clock is enabled too.
Remove the superfluous clock acquisition and enable in DaVinci
NAND driver.
Tested on K2L, K2HK, K2E, DA850 EVM, DA850 LCDK in device-tree
boot and DM644x EVM in legacy boot.
