2018-07-18dt-bindings: clock: add rk3399 DDR3 standard speed bins.Enric Balletbo i Serra
DDR3 SDRAM Standard (JESD79-3F) defines some standard speed bins for DDR3 memories. The rk3399_dmc driver allows you to pass these values via the device tree. For that purpose the devfreq/rk3399_dmc.txt binding refers to a ddr.h file which does not exist. This patch adds the missing defines in a include file called rk3399-ddr.h with the definition of standard speed bins according to the ARM Trusted Firmware (ATF).

2017-12-26dt-bindings: Use lower case hex in unit-addressesRob Herring
DT unit addresses should be lower case hex. Fix all the binding examples. Converted with the following command from Krzysztof Kozlowski: sed -e 's/@\([a-fA-F0-9_-]*\) {/@\L\1 {/' -i $(find Documentation/devicetree/bindings -name '*.txt') Signed-off-by: Rob Herring <robh@kernel.org>

2017-09-05dt-bindings: Remove "status" from examplesRob Herring
Pretty much any node can have a status property, so it doesn't need to be in examples.

Compiling the DT file with W=1, DTC warns like follows: Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a unit name, but no reg property Fix this by replacing '@' with '-' as the OPP nodes will never have a "reg" property.
