Rockchip boards may depend on a working MMC regulator in SPL to successfully load FIT payload from MMC. Typically, these boards only include the vmmc-supply regulator and not its vin-supply in SPL control FDT. The commitf98d812e53("power: regulator: Add vin-supply for GPIO and Fixed regulators") breaks loading FIT from MMC in SPL on some of these boards due to now requiring the vin-supply to be included in the SPL control FDT. The commit also strangely enables any found vin-supply in regulator_common_of_to_plat() and not when a regulator is enabled or as part of regulator_autoset(). Revert the commit to fix FIT loading in SPL on broken boards. If a board needs to have its vin-supply enabled, two options come to mind: - Add regulator-always-on prop to the regulator in the -u-boot.dtsi for any board. - Implement full support for reference counting of regulators and then update the regulator-uclass to enable any found vin-supply when a regulator is enabled. This reverts commitf98d812e53. Reported-by: Dang Huynh <danct12@riseup.net> Signed-off-by: Jonas Karlman <jonas@kwiboo.se> Reviewed-by: Dragan Simic <dsimic@manjaro.org>
