Convert nvmem_add_cells_from_of() to use the new nvmem_add_one_cell().
This will remove duplicate code and it will make it possible to add a
hook to a nvmem layout in between, which can change fields before the
cell is finally added.

Add a new function to add exactly one cell. This will be used by the
nvmem layout drivers to add custom cells. In contrast to the
nvmem_add_cells(), this has the advantage that we don't have to assemble
a list of cells on runtime.

If nvmem_add_cells() fails, the whole nvmem_register() will fail
and the cells will then be removed anyway. This is a preparation
to introduce a nvmem_add_one_cell() which can then be used by
nvmem_add_cells().
This is then the same to what nvmem_add_cells_from_table() and
nvmem_add_cells_from_of() do.

struct nvmem_cell_info is used to describe a cell. Thus this should
really be in the nvmem-provider's header. There are two (unused) nvmem
access methods which use the nvmem_cell_info to describe the cell to be
accesses. One can argue, that they will create a cell before accessing,
thus they are both a provider and a consumer.
struct nvmem_cell_info will get used more and more by nvmem-providers,
don't force them to also include the consumer header, although they are
not.

Sometimes a cell can represend multiple values. For example, a base
ethernet address stored in the NVMEM can be expanded into multiple
discreet ones by adding an offset.
For this use case, introduce an index parameter which is then used to
distiguish between values. This parameter will then be passed to the
post process hook which can then use it to create different values
during reading.
At the moment, there is only support for the device tree path. You can
add the index to the phandle, e.g.
&net {
nvmem-cells = <&base_mac_address 2>;
nvmem-cell-names = "mac-address";
};
&nvmem_provider {
base_mac_address: base-mac-address@0 {
#nvmem-cell-cells = <1>;
reg = <0 6>;
};
};

Sometimes, future bindings for phandles will get additional arguments.
Thus the target node of the phandle will need a new #.*-cells property.

Add a new variant of the of_parse_phandle_with_args() which treats the
cells name as optional. If it's missing, it is assumed that the phandle
has no arguments.
Up until now, a nvmem node didn't have any arguments, so all the device
trees haven't any '#*-cells' property. But there is a need for an
additional argument for the phandle, for which we need a '#*-cells'
property. Therefore, we need to support nvmem nodes with and without
this property.

Pull powerpc fixes from Michael Ellerman:
"It's a bit of a big batch for rc6, but just because I didn't send any
fixes the last week or two while I was on vacation, next week should
be quieter:
- Fix a few objtool warnings since we recently enabled objtool.
- Fix a deadlock with the hash MMU vs perf record.
- Fix perf profiling of asynchronous interrupt handlers.
- Revert the IMC PMU nest_init_lock to being a mutex.
- Two commits fixing problems with the kexec_file FDT size
estimation.
- Two commits fixing problems with strict RWX vs kernels running at
non-zero.
- Reconnect tlb_flush() to hash__tlb_flush()
Thanks to Kajol Jain, Nicholas Piggin, Sachin Sant Sathvika Vasireddy,
and Sourabh Jain"

When iterating on a linked list, a result of memremap is dereferenced
without checking it for NULL.
This patch adds a check that falls back on allocating a new page in
case memremap doesn't succeed.

[ardb: return -ENOMEM instead of breaking out of the loop]
Signed-off-by: Ard Biesheuvel <ardb@kernel.org>
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time. To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic
at once.

========
- Fixed the module description
MHI Endpoint
============
- Powered down the MHI EP stack completely during MHI RESET instead of just
doing transfer abort as the MMIO register access will be prohibited
afterwards. EP stack will also be powered on again in case the RESET
happened due to SYS_ERR.
- Added a sanity check before processing the command ring to make sure that
the channel is supported by the controller.
- Added a check to make sure the xfer_cb is available for the channel
before trying to send the error status to the client drivers. This
helps in avoiding a potential null pointer dereference.
- Fixed the debug log of RESET command
- Modified the channel ring handler lock to protect the whole handler
instead of locking it partially. This helps in avoiding a race that may
happen if a channel STOP/RESET command is issued by the host parallely.
- Saved the MHI state locally during suspend and resume. Otherwise, the MHI
EP stack will not be aware of a channel that got disabled and may try to
access it later.
- Changed the MHI state_lock to mutex instead of spinlock. This helps in
avoiding the sleeping in atomic bug reported by Dan Carpenter and also
allows the lock to be held throughout the state change.
- Fixed the off by one error while doing the MHI channel check during
command ring processing.
MHI Generic
===========
- Updated the MHI toplevel Makefile to use Kconfig flags for building the
host and endpoint sub-directories conditionally.
