The regulator always-on property should only be used for regulators that either can't be disabled or the drivers for the client devices are not enabling the regulator and so being disabled due to unused.
There are some max77802 regulators in the Peach Pit and Pi boards that are always-on but shouldn't since they are enabled by drivers: BUCK5 is max77802 inl1 supply BUCK7 is max77802 inl{2,10} supply BUCK9 is max77802 inl{3,4,5,7} supply BUCK10 is mmc1 vqmmc supply LDO9 is adc vdd supply This patch removes the always-on property for these regulators. Some regulators should remain always-on even when they are used as input supplies, because these regulators are also used by other components that are not described in the DT, for example: LDO10 is hdmi vdd_osc supply but it's also used as input supply for the Exynos5420 temperature sensor. LDO8 is hdmi vdd and vdd_pll supply but it's also used as supply for the Exynos5420 Display port. BUCK2 and BUCK6 are the vdd supplies for the EAGLE and KFC clusters.
