686a639c02 dt-bindings: watchdog: npcm: add GCR syscon property
NPCM750 and NPCM845 latch watchdog reset indications in the SoC
GCR block rather than in the watchdog block itself.

Add the optional nuvoton,sysgcr phandle so watchdog nodes can
reference the shared GCR reset-status registers that hold those
latched watchdog reset indications.

This is needed by the following reset-status support, which reads
those latches and reports watchdog-caused resets through bootstatus.

When the bindings for the Renesas RZ/V2H(P) SoC were factored
out IP WDT0 was selected for the example, however the HW user
manual states that only IP WDT1 can be used by Linux.

This commit is part of a series that removes WDT{0,2,3} support
from the kernel, therefore the example from the bindings has
lost its meaning.

8fa8380abd dt-bindings: watchdog: samsung-wdt: Split if:then: and constrain more
Binding defined two if:then: blocks covering different conditions but
not fully constraining the properties per each variant:
1. "if:" to require samsung,syscon-phandle,
2. "if:" with "else:" to narrow number of clocks and require or disallow
   samsung,cluster-index.

This still did not cover following cases:
1. Disallow samsung,syscon-phandle when not applicable,
2. Narrow samsung,cluster-index to [0, 1], for SoCs with only two
   clusters.

Solving this in current format would lead to spaghetti code, so re-write
entire "if:then:" approach into mutually exclusive cases so each SoC
appears only in one "if:" block.  This allows to forbid
samsung,syscon-phandle for S3C6410, and narrow samsung,cluster-index
to [0, 1].

2023.  There are no in-kernel users of samsung,s3c2410-wdt compatible
anymore and platform is so old, that there should be no out-of-tree
