How presence of some > clock affects name of other clock and its place/location in list of clocks? qcom,sdm845-ufshc has 9 clocks, one of which is rx_lane1_sync_clk. qcom,sm6115-ufshc has 8 clocks (all of the ones in sdm845 without rx_lane1_sync_clk). So if I'm understanding correctly, you want to put the sm6115 with sdm845, which means re-use the clocks and reg specification from sdm845, which means sm6115 will "inherit" this rx_lane1_sync_clk, and then I have to put it in DT (otherwise the schema would complain), and I'm asking if I can put an empty (i.e <0 0>) value, so schema is satisfied but clock is still not really passed. > Best regards, > Krzysztof ^ permalink raw reply [flat|nested] 6+ messages in thread

No. I want to use the same order and naming as sdm845 variant, but in your own/dedicated if:else: entry. Just do not create inconsistencies when not needed. If inconsistency is needed here (which I think is not), please explain more. Best regards, Krzysztof ^ permalink raw reply [flat|nested] 6+ messages in thread
