2020-06-15dt-bindings: property-units: Add picoseconds typeDan Murphy1-0/+1
Add the '-ps' picosecond unit suffix for property names. Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Rob Herring <robh@kernel.org>
2020-05-13dt-bindings: opp: Introduce opp-peak-kBps and opp-avg-kBps bindingsSaravana Kannan1-0/+4
Interconnects often quantify their performance points in terms of bandwidth. So, add opp-peak-kBps (required) and opp-avg-kBps (optional) to allow specifying Bandwidth OPP tables in DT. opp-peak-kBps is a required property that replaces opp-hz for Bandwidth OPP tables. opp-avg-kBps is an optional property that can be used in Bandwidth OPP tables.

2019-06-13dt-bindings: property-units: Sanitize unit namingGeert Uytterhoeven1-17/+17
Make the naming of units consistent with common practices: - Do not capitalize the first character of units ("Celsius" is special, as it is not the unit name, but a reference to its proposer), - Do not use plural for units, - Do not abbreviate "ampere", - Concatenate prefixes and units (no spaces or hyphens), - Separate units by spaces not hyphens, - "milli" applies to "degree", not to "Celsius".

2019-01-22devicetree: property-units: Add femtofarads unitSam Ravnborg1-0/+1
When dealing with capacitance of 0.5 pF then a smaller unit is preferred. Add femtofarads to deal with this.

2016-02-12dt/bindings: add documentation on standard property unit suffixesRob Herring1-0/+39
A common review comment is to add units to DT property names. The naming convention is inconsistent unfortunately although there are clear majorities in use already. This makes it hard to remember the exact name preferred, so I'm documenting this to provide an easy point of reference.
