The npcm845 i3c devicetree binding follows the basic i3c bindings
and add the properties for allowing to adjust the SDA/SCL timing
to meet different requirements.

+      The i3c open drain frequency is 1MHz by default.
+      If need to use different frequency, specify the clock high/low period directly.
+      i3c-od-scl-hi-perios-ns specifies the high period ns of the SCL clock cycle in open drain mode.
+      When i3c-od-scl-hi-period-ns and i3c-od-scl-lo-period-ns are specified, the i3c od frequency is
+      decided by these two properties.
+      i3c-od-scl-hi-period-ns should be equal to i3c-pp-scl-hi-period-ns or i3c-od-scl-lo-period-ns.
