Could make plug it into the sdhci node on some > board? Actually I have an ipq6010 sdcard device with pmic, which needs to reference ipq6018_l2. Also on the downstream qsdk kernel, the sdhc node writes 'vqmmc-supply = <&ipq6018_l2>;' by default. > Essentially, why is it needed upstream, when there are no user? Most ipq60xx devices have pmic chips, including some ipq6000 devices, while another ipq6000 devices do not have the pmic chips. So it does not mean there are no users but the supply is board specific. Maybe we should move the mp5496 node outside of ipq6018.dtsi. Thanks, Chukun -- 2.25.1
