Subsequent generations of Tegra, such as Tegra194, contain a completely
different set of GPIOs. In order to clarify that the Tegra186 defines
are indeed specific to Tegra186, change the prefix from TEGRA_ to
TEGRA186_.
Note that for now we need to keep the old definitions in place to avoid
breaking compilation in file that use this header. Once all users have
been converted to use the new defines, the old ones can be removed.
Also note that this is only a naming change and doesn't affect device
tree ABI.

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.

->setup_data_interface() is a controller specific method and should
thus be placed in nand_controller_ops.
In order to make that work with controllers that support keeping
pre-configured timings we need to add a new NAND_KEEP_TIMINGS flag to
inform the core it should skip the timings selection step.

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

In order to deprecate the ->select_chip hook we need to pass the CS
line a NAND operations are targeting. This is done through the
addition of a cs field to the nand_operation struct.
We also need to keep track of the currently selected target to
properly initialize op->cs, hence the ->cur_cs field addition to the
nand_chip struct.
Note that op->cs is not assigned in nand_exec_op() because we might
rework the way we execute NAND operations in the future (adopt a
queuing mechanism instead of the serialization we have right now).

Currently dma_mapping_error returns a boolean as int, with 1 meaning
error. This is rather unusual and many callers have to convert it to
errno value. The callers are highly inconsistent with error codes
ranging from -ENOMEM over -EIO, -EINVAL and -EFAULT ranging to -EAGAIN.
Return -ENOMEM which seems to be what the largest number of callers
convert it to, and which also matches the typical error case where
we are out of resources.

Error handling of the dma_map_single and dma_map_page APIs is a little
problematic at the moment, in that we use different encodings in the
returned dma_addr_t to indicate an error. That means we require an
additional indirect call to figure out if a dma mapping call returned
an error, and a lot of boilerplate code to implement these semantics.
Instead return the maximum addressable value as the error. As long
as we don't allow mapping single-byte ranges with single-byte alignment
this value can never be a valid return. Additionaly if drivers do
not check the return value from the dma_map* routines this values means
they will generally not be pointed to actual memory.
Once the default value is added here we can start removing the
various mapping_error methods and just rely on this generic check.

commit - add a new config option that tells nvmem not to use the DT
node of the parent device.
This way we won't be creating nvmem devices corresponding with MTD

Once a set of bindings for MTD nvmem cells is agreed upon, we'll be
