However, if a controller like PCIe have multiple clocks & resets and they need to be enabled in a sequence, driver must use standalone function tegra_powergate_power_on() to power up partition. Export tegra_powergate_power_on() to allow Tegra controller drivers to unpower gate partition independent to clock & reset.
