The security implementation is too chatty. For example, the common case
is that security is not enabled / setup, and booting a qemu
configuration currently yields:
nvdimm nmem0: request_key() found no key
nvdimm nmem0: failed to unlock dimm: -126
nvdimm nmem1: request_key() found no key
nvdimm nmem1: failed to unlock dimm: -126

The PM816 module is a versatile PMIC with many diverse functions
integrated, including, a watchdog.
This watchdog is subcomponent of the PON (Power On) peripheral,
in the same way as pwrkey/resin buttons.
It works with two timers (2-stages), the first one generates an
IRQ to the main SoC (APQ8016/MSM8916), the second one performs
the reset.
This driver expects the following device hierarchy:
[pm8916]->[pm8916-pon]->[pm8916-wdt]
It uses the pm8916 regmap to access PM8916 registers.

Convert string compares of DT node names to use of_node_name_{eq,prefix}
helpers instead. This removes direct access to the node name pointer.
This changes a single case insensitive node name comparison to case
sensitive for "ata4". This is the only instance of a case insensitive
comparison for all the open coded node name comparisons on powerpc.
Searching the commit history, there doesn't appear to be any reason for
it to be case insensitive.
A couple of open coded iterating thru the child node names are converted
to use for_each_child_of_node() instead.

1b. Set Passphrase to DIMM X.
2. Write to

With Intel DSM 1.8 [1] two new security DSMs are introduced. Enable/update
master passphrase and master secure erase. The master passphrase allows
a secure erase to be performed without the user passphrase that is set on
the NVDIMM. The commands of master_update and master_erase are added to
the sysfs knob in order to initiate the DSMs. They are similar in opeartion
mechanism compare to update and erase.

Add support for the NVDIMM_FAMILY_INTEL "ovewrite" capability as
described by the Intel DSM spec v1.7. This will allow triggering of
overwrite on Intel NVDIMMs. The overwrite operation can take tens of
minutes. When the overwrite DSM is issued successfully, the NVDIMMs will
be unaccessible. The kernel will do backoff polling to detect when the
overwrite process is completed. According to the DSM spec v1.7, the 128G
NVDIMMs can take up to 15mins to perform overwrite and larger DIMMs will
take longer.
Given that overwrite puts the DIMM in an indeterminate state until it
completes introduce the NDD_SECURITY_OVERWRITE flag to prevent other
operations from executing when overwrite is happening. The
NDD_WORK_PENDING flag is added to denote that there is a device reference
on the nvdimm device for an async workqueue thread context.

The x/y command parsing has been broken since commit 129957069e6a
("staging: panel: Fixed checkpatch warning about simple_strtoul()").
Commit b34050fadb86 ("auxdisplay: charlcd: Fix and clean up handling of
x/y commands") fixed some problems by rewriting the parsing code,
but also broke things further by removing the check for a complete
command before attempting to parse it. As a result, parsing is
terminated at the first x or y character.
This reinstates the check for a final semicolon. Whereas the original
code use strchr(), this is wasteful seeing as the semicolon is always
at the end of the buffer. Thus check this character directly instead.

The function of_find_node_by_path() acquires a reference to the node
returned by it and that reference needs to be dropped by its caller.
su_get_type() doesn't do that. The match node are used as an identifier
to compare against the current node, so we can directly drop the refcount
after getting the node from the path as it is not used as pointer.
Fix this by use a single variable and drop the refcount right after
of_find_node_by_path().
