Subject[PATCH 5.18 11/11] dt-bindings: nvmem: sfp: Add clock properties
Date
From: Sean Anderson <sean.anderson@seco.com>

commit 8cb0cd68bef75af5ac8ef93f3314d4f8dc8767a3 upstream.

To program fuses, it is necessary to set the fuse programming time. This
is determined based on the value of the platform clock. Add a clock
property.

Because this property is necessary for programming, it is made
mandatory. Since these bindings have not yet been present in a stable
release (though they are on track for 5.18), it is not an ABI break to
change them in this manner.
