Many of these were not integrated in the earlier series (e.g., the OPPs changed before production; earlier patchsets used pre-production numbers). Along the way, it seemed worthwhile to convert the binding docs to a schema. Among other reasons, it actually helped catch several errors and omissions in translation between downstream device trees and the version that actually landed upstream. See the patches for further details. Regards, Brian Changes in v4: * Update .yaml to use more "default" entries, instead of free-form text * s/phandle-array/phandle/ * Move to .../memory-controllers, update filename Changes in v3: * Add |maxItems| for devfreq-events * Improve deprecation notes * Add Reviewed-by tags * Collect some Acked/Reviewed tags Changes in v2: * Fix yamllint issues * Adapt to various review comments (use of *-hz, hyphens, node naming) * Add a few new bugfixes * Add some new properties (ported from downstream kernels) required for stability * Convert more properties from "cycles" to "nanoseconds" Brian Norris (13): dt-bindings: devfreq: rk3399_dmc: Convert to YAML dt-bindings: devfreq: rk3399_dmc: Deprecate unused/redundant properties dt-bindings: devfreq: rk3399_dmc: Fix Hz units dt-bindings: devfreq: rk3399_dmc: Specify idle params in nanoseconds dt-bindings: devfreq: rk3399_dmc: Add more disable-freq properties PM / devfreq: rk3399_dmc: Drop undocumented ondemand DT props PM / devfreq: rk3399_dmc: Drop excess timing properties PM / devfreq: rk3399_dmc: Use bitfield macro definitions for ODT_PD PM / devfreq: rk3399_dmc: Support new disable-freq properties PM / devfreq: rk3399_dmc: Support new *-ns properties PM / devfreq: rk3399_dmc: Disable edev on remove() PM / devfreq: rk3399_dmc: Use devm_pm_opp_of_add_table() PM / devfreq: rk3399_dmc: Avoid static (reused) profile Lin Huang (2): arm64: dts: rk3399: Add dfi and dmc nodes arm64: dts: rockchip: Enable dmc and dfi nodes on gru .../bindings/devfreq/rk3399_dmc.txt | 212 ---------- .../rockchip,rk3399-dmc.yaml | 384 ++++++++++++++++++ .../dts/rockchip/rk3399-gru-chromebook.dtsi | 7 + .../boot/dts/rockchip/rk3399-gru-scarlet.dtsi | 12 + arch/arm64/boot/dts/rockchip/rk3399-gru.dtsi | 28 ++ .../boot/dts/rockchip/rk3399-op1-opp.dtsi | 25 ++ arch/arm64/boot/dts/rockchip/rk3399.dtsi | 19 + drivers/devfreq/rk3399_dmc.c | 299 ++++++-------- 8 files changed, 609 insertions(+), 377 deletions(-) delete mode 100644 Documentation/devicetree/bindings/devfreq/rk3399_dmc.txt create mode 100644 Documentation/devicetree/bindings/memory-controllers/rockchip,rk3399-dmc.yaml
