Hi, The structure rockchip_clk_provider needs to refer the GRF regmap in somewhere, if the CRU node has not "rockchip,grf" property, calling syscon_regmap_lookup_by_phandle will return an invalid GRF regmap, and the MUXGRF type clock will be not supported. Therefore, we need to add them. Thanks. Changes in v4: - separte the binding patch - update the decription for rockchip,grf property Changes in v3: - add optional roperty rockchip,grf in rockchip,rk3399-cru.txt Changes in v2: - referring pmugrf for PMUGRU - fix the typo "invaild" in COMMIT message Xing Zheng (2): arm64: dts: rockchip: add "rockchip, grf" property for RK3399 PMUCRU/CRU dt-bindings: clk: add rockchip,grf property for RK3399 Documentation/devicetree/bindings/clock/rockchip,rk3399-cru.txt | 6 ++++++ arch/arm64/boot/dts/rockchip/rk3399.dtsi | 2 ++ 2 files changed, 8 insertions(+) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
