2018-07-18dt-bindings: devfreq: rk3399_dmc: move interrupts to be optional.Enric Balletbo i Serra1-4/+6
In ATF we already wait for DDR DVFS finish, so move the interrupts properties to be optional.

2018-07-18dt-bindings: clock: add rk3399 DDR3 standard speed bins.Enric Balletbo i Serra1-1/+1
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).

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.
