dt-bindings: devfreq: tegra30-actmon: Add cooling-cells

2021-06-17T08:08:57+00:00

The ACTMON watches activity of memory clients. Decisions about a minimum
required frequency are made based on the info from ACTMON. We can use
ACTMON as a thermal cooling device by limiting the required frequency.
Document new cooling-cells property of NVIDIA Tegra ACTMON hardware unit.

dt-bindings: devfreq: rk3399_dmc: Add rockchip,pmu phandle.

2021-04-08T04:14:50+00:00

The Rockchip DMC (Dynamic Memory Interface) needs to access to the PMU
general register files to know the DRAM type, so add a phandle to the
syscon that manages these registers.

dt-bindings: devfreq: Add documentation for the interconnect properties

2020-11-13T09:10:27+00:00

Add documentation for new optional properties in the exynos bus nodes:
interconnects, #interconnect-cells, samsung,data-clock-ratio.
These properties allow to specify the SoC interconnect structure which
then allows the interconnect consumer devices to request specific
bandwidth requirements.

dt-bindings: clock: add rk3399 DDR3 standard speed bins.

2018-07-18T04:58:30+00:00

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).
