The test clock isn't in the bindings and apparently it's not used by anyone upstream. Remove it. Suggested-by:

In the new world input clocks should be matched by ".fw_name". sc7180 is new enough that no backward compatibility use of global names should be needed. Remove it. With a proper device tree and downstream display patches I have verified booting a sc7180 up and seeing the display after this patch.

The qcom,dispcc bindings had a few problems with them: 1. They didn't specify all the clocks that dispcc is a client of. Specifically on sc7180 there are two clocks from the DSI PHY and two from the DP PHY. On sdm845 there are actually two DSI PHYs (each of which has two clocks) and an extra clock from the gcc. These all need to be specified. 2. The sdm845.dtsi has existed for quite some time without specifying the clocks. The Linux driver was relying on global names to match things up. While we should transition things, it should be noted in the bindings. 3. The names used the bindings for "xo" and "gpll0" didn't match the names that QC used for these clocks internally and this was causing confusion / difficulty with their code generation tools. Switched to the internal names to simplify everyone's lives. It's not quite as clean in a purist sense but it should avoid headaches. This officially changes the binding, but that seems OK in this case. Also note that I updated the example.

The 'qcom,gcc.yaml' file failed self-validation (dt_binding_check) because it required a property to be either (3 entries big), (3 entries big), or (7 entries big), but not more than one of those things. That didn't make a ton of sense. This patch splits all of the exceptional device trees (AKA those that would have needed if/then/else rules) from qcom,gcc.yaml. It also cleans up some cruft found while doing that. After this lands, this worked for me atop clk-next with just the known error about msm8998: for f in \ Documentation/devicetree/bindings/clock/qcom,gcc-apq8064.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-ipq8074.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-msm8996.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-msm8998.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-qcs404.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-sc7180.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc-sm8150.yaml \ Documentation/devicetree/bindings/clock/qcom,gcc.yaml; do \ ARCH=arm64 make dtbs_check DT_SCHEMA_FILES=$f; \ done I then picked this patch atop linux-next (next-20200129) and ran: # Delete broken yaml: rm Documentation/devicetree/bindings/pci/intel-gw-pcie.yaml ARCH=arm64 make dt_binding_check | grep 'clock/qcom' ...and that didn't seem to indicate problems. Arbitrary decisions made (yell if you want changed): - Left all the older devices (where clocks / clock-names weren't specified) in a single file. - Didn't make clocks "required" for msm8996 but left them as listed. This seems a little weird but it matches the old binding. Misc cleanups as part of this patch: - Fixed schema id to not have "bindings/" as per Rob [1]. - Listed include files as per Stephen. - sm8150 was claimed to be same set of clocks as sc7180, but driver and dts appear to say that "bi_tcxo_ao" doesn't exist. Fixed. - In "apq8064", "#thermal-sensor-cells" was missing the "#". - Got rid of "|" at the end of top description since spacing doesn't matter. - Changed indentation to consistently 2 spaces (it was 3 in some places). - Added period at the end of protected-clocks description. - No space before ":". - Updated sc7180/sm8150 example to use the 'qcom,rpmh.h' include. - Updated sc7180/sm8150 example to use larger address/size cells as per reality. - Updated sc7180/sm8150 example to point to the sleep_clk rather than <0>. - Made it so that gcc-ipq8074 didn't require #power-domain-cells since actual dts didn't have it and I got no hits from: git grep _GDSC include/dt-bindings/clock/qcom,gcc-ipq8074.h - Made it so that gcc-qcs404 didn't require #power-domain-cells since actual dts didn't have it and I got no hits from: git grep _GDSC include/dt-bindings/clock/qcom,gcc-qcs404.h Noticed, but not done in this patch (volunteers needed): - Add "aud_ref_clk" to sm8150 bindings / dts even though I found a reference to it in "gcc-sm8150.c". - Fix node name in actual ipq8074 to be "clock-controller" (it's gcc). - Since the example doesn't need phandes to exist, in msm8998 could just make up places providing some of the clocks currently bogused out with <0>. - On msm8998 clocks are listed as required but current dts doesn't have them.

The DFS frequency table logic overwrites 'cfg' while detecting the parent clk and then later on in clk_rcg2_dfs_populate_freq() we use that same variable to figure out the mode of the clk, either MND or not. Add a new variable to hold the parent clk bit so that 'cfg' is left untouched for use later. This fixes problems in detecting the supported frequencies for any clks in DFS mode.

zynqmp_clk_divider_round_rate() returns actual divider value after calculating from parent rate and desired rate, even though that rate is not supported by single divider of hardware. It is also possible that such divisor value can be achieved through 2 different dividers. As, Linux tries to set such divisor value(out of range) in single divider set divider is getting failed. Fix the same by computing best possible combination of two divisors which provides more accurate clock rate. Signed-off-by:

We currently have a hidden dependency to the device tree node name for the clkctrl clocks. Instead of using standard node name like "clock", we must use "l4-per-clkctrl" type naming so the clock driver can find the associated clock domain. Further, if "clk" is specified for a clock node name, the driver sets TI_CLK_CLKCTRL_COMPAT flag that uses different logic for the clock name based on the parent node name for the all the clkctrl clocks for the SoC. If the clock node naming dependency is not understood, the related clockdomain is not found, or a wrong one can get used if a clock manager has multiple clock domains. As each clkctrl instance represents a single clock domain, let's allow using domain specific compatible names to specify the clock domain. This simplifies things and removes the hidden dependency to the node name. And then later on, after the node names have been standardized, we can drop the related code for parsing the node names. Let's also update the binding to use standard "clock" node naming instead of "clk" and add the missing description for reg.

This is similar to what we have for omap5 except the gpu_cm address is different, the mux clocks have one more source option, and there's no divider clock. Note that because of the current dts node name dependency for mapping to clock domain, we must still use "gpu-clkctrl@" naming instead of generic "clock@" naming for the node. And because of this, it's probably best to apply the dts node addition together along with the other clock changes. For accessing the GPU, we also need to configure the interconnect target module for GPU similar to what we have for omap5, I'll send that change separately. Cc: Benoit Parrot <bparrot@ti.com> Cc: "H.

The parent clk for gmac clk ctrl has to be gmac_main_clk (125MHz) instead of dpll_gmac_ck (1GHz). This is caused incorrect CPSW MDIO operation. Hence, fix it. Fixes: dffa9051 ('clk: ti: dra7: add new clkctrl data') Signed-off-by:

Most of the clock related dt-binding header files are located in dt-bindings/clock folder. It would be good to keep all the similar header files at a single location. Suggested-by:
