"serdes" node (child node of WIZ) can have sub-nodes for representing links
or it can have sub-nodes for representing the various clocks within the
serdes. Instead of trying to read "reg" from every child node used for
assigning "lane_phy_type", read only if the child node's name is "phy"
or "link" subnode.
Ideally all PHY dt nodes should have node name as "phy", however
existing devicetree used "link" as subnode. So in order to maintain old
DT compatibility get PHY properties for "phy" or "link" subnode.

Cadence Sierra PHY driver registers PHY using devm_phy_create()
for all sub-nodes of Sierra device tree node. However Sierra device
tree node can have sub-nodes for the various clocks in addtion to the
PHY. Use devm_phy_create() only for nodes with name "phy" (or "link"
for old device tree) which represent the actual PHY.

Invoke wiz_init() before configuring anything else in Sierra/Torrent
(invoked as part of of_platform_device_create()). wiz_init() resets the
SERDES device and any configuration done in the probe() of
Sierra/Torrent will be lost. In order to prevent SERDES configuration
from getting reset, invoke wiz_init() immediately before invoking
of_platform_device_create().

Commit 44d30d622821d ("phy: cadence: Add driver for Sierra PHY")
de-asserts PHY_RESET even before the configurations are loaded in
phy_init(). However PHY_RESET should be de-asserted only after
all the configurations has been initialized, instead of de-asserting
in probe. Fix it here.

commit 091876cc355d ("phy: ti: j721e-wiz: Add support for WIZ module
present in TI J721E SoC") modeled the internal clocks depending on the
subnodes that are populated in device tree. However recent discussions
in the mailing list [1] suggested to just add #clock cells in the parent
DT node and model the clocks within the driver.
Model the mux clocks without device tree input for AM64x SoC. Don't
remove the earlier design since DT nodes for J7200 and J721e are already
upstreamed.

Both "struct wiz_clk_div_sel" and "struct wiz_clk_mux_sel" are static
data that is common for all wiz instances. Including
"struct regmap_field" for each of the wiz instances can yield undesirable
results. Move "struct regmap_field" out of "struct wiz_clk_div_sel" and
"struct wiz_clk_mux_sel" and make them point to constant data.
So far no issues are observed since both these structures are not
accessed outside the probe.

In case we have already established connection to nvmf target, it
shouldn't be allowed to change the model_number. E.g. if someone will
identify ctrl and get model_number of "my_model" later on will change
the model_numbel via configfs to "my_new_model" this will break the NVMe
specification for "Get Log Page – Persistent Event Log" that refers to
Model Number as: "This field contains the same value as reported in the
Model Number field of the Identify Controller data structure, bytes
63:24."
Although it doesn't mentioned explicitly that this field can't be
changed, we can assume it.
So allow setting this field only once: using configfs or in the first
identify ctrl operation.

Currently kato is initialized to NVME_DEFAULT_KATO for both
discovery & i/o controllers. This is a problem specifically
for non-persistent discovery controllers since it always ends
up with a non-zero kato value. Fix this by initializing kato
to zero instead, and ensuring various controllers are assigned
appropriate kato values as follows:
non-persistent controllers - kato set to zero
persistent controllers - kato set to NVMF_DEV_DISC_TMO
(or any positive int via nvme-cli)
i/o controllers - kato set to NVME_DEFAULT_KATO
(or any positive int via nvme-cli)

The hwmon pointer wont be NULL if the registration fails. Though the
exit code path will assign it to ctrl->hwmon_device. Later
nvme_hwmon_exit() will try to free the invalid pointer. Avoid this by
returning the error code from hwmon_device_register_with_info().

My 2TB SKC2000 showed the exact same symptoms that were provided
in 538e4a8c57 ("nvme-pci: avoid the deepest sleep state on
Kingston A2000 SSDs"), i.e. a complete NVME lockup that needed
cold boot to get it back.
According to some sources, the A2000 is simply a rebadged
SKC2000 with a slightly optimized firmware.
Adding the SKC2000 PCI ID to the quirk list with the same workaround
as the A2000 made my laptop survive a 5 hours long Yocto bootstrap
buildfest which reliably triggered the SSD lockup previously.

The kernel fails to fully detect these SSDs, only the character devices
are present:

[ 13.239627] nvme nvme0: Identify Descriptors failed (8194)
[ 13.246315] nvme nvme1: Identify Descriptors failed (8194)
Adding the NVME_QUIRK_NO_NS_DESC_LIST fixes this problem.
