2cc3b37f5b nvmem: add explicit config option to read old syntax fixed OF cells
Binding for fixed NVMEM cells defined directly as NVMEM device subnodes
has been deprecated. It has been replaced by the "fixed-layout" NVMEM
layout binding.

New syntax is meant to be clearer and should help avoiding imprecise
bindings.

NVMEM subsystem already supports the new binding. It should be a good
idea to limit support for old syntax to existing drivers that actually
support & use it (we can't break backward compatibility!). That way we
additionally encourage new bindings & drivers to ignore deprecated
binding.

It wasn't clear (to me) if rtc and w1 code actually uses old syntax
fixed cells. I enabled them to don't risk any breakage.

9bf75da0e2 nvmem: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

095bb8ba45 nvmem: sunplus-ocotp: release otp->clk before return
Smatch reports:
drivers/nvmem/sunplus-ocotp.c:205 sp_ocotp_probe()
warn: 'otp->clk' from clk_prepare() not released on lines: 196.

In the function sp_ocotp_probe(struct platform_device *pdev), otp->clk may
not be released before return.

To fix this issue, using function clk_unprepare() to release otp->clk.

874dfbcf21 nvmem: sunplus-ocotp: drop useless probe confirmation
Printing probe success is discouraged, because we can use tracing for
this purpose.  Remove useless print message after Sunplus OCOTP driver
probe.

1066f81563 nvmem: sunplus-ocotp: staticize sp_otp_v0
The "sp_otp_v0" file scope variable is not used outside, so make it
static to fix warning:

  drivers/nvmem/sunplus-ocotp.c:74:29: sparse:
    sparse: symbol 'sp_otp_v0' was not declared. Should it be static?
