Yes but taking a random example from a PMIC vdd-l2-l13-l14-supply is specific to a given PMIC, so you need to name it specifically wrt its PMIC pin-name whereas csiphyX-1p2 is there for every CSIPHY we have. For example on qcom2290 there's a shared power-pin for VDD_A_CAMSS_PLL_1P8 but then individual power-pins for VDD_A_CSI_0_1P2 and VDD_A_CSI_1_1P2. If we follow the general proposal of vdd-csiphyX-1p2-supply vdd-csiphyX-0p9-supply in the yaml, then whether SoCs like qcm2290 share 1p8 or SoCs like sm8650, sm8450, x1e have individual 1p8 pins is up to the dtsi to decide. --- bod
