Subject: dt-bindings: pincfg-node: Add properties 'skew-delay-{in,out}put-ps'
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5c284d086bcf3bcfe54debb44a18fb218f91c010;p=thirdparty%2Fkernel%2Fstable.git

dt-bindings: pincfg-node: Add properties 'skew-delay-{in,out}put-ps'

Add the properties 'skew-delay-input-ps' and 'skew-delay-output-ps'
to specify independent skew delay value for the two pin's directions.
Make the new properties unavailable when the existing property
'skew-delay' is selected.
