The Tegra PMC driver implements a restart handler that supports Tegra specific reboot commands such as placing the device into 'recovery' mode in order to reprogram the platform. This is accomplished by setting the appropriate bit in the PMC scratch0 register prior to rebooting the platform. For Tegra platforms that support PSCI or EFI, the default Tegra restart handler is not called and the PSCI or EFI restart handler is called instead. Hence, for Tegra platforms that support PSCI or EFI, the Tegra specific reboot commands do not currently work. Fix this by moving the code that programs the PMC scratch0 register into a separate reboot notifier that will always be called on reboot. Signed-off-by:

Previously we assumed that devm_tegra_core_dev_init_opp_table() will be used only by drivers that will always have device with OPP table, but this is not true anymore. For example now Tegra30 will have OPP table for PWM, but Tegra20 not and both use the same driver. Hence let's not print the error message about missing OPP table in the common helper, we can print it elsewhere. Reviewed-by:

PM_INIT_FINALIZE tells the PMU FW that Linux is able to handle the power management nodes that are provided by the PMU FW. Nodes that are not requested are shut down after this call. Calling PM_INIT_FINALIZE from the zynqmp_power driver is wrong. The PM node request mechanism is implemented in the zynqmp_pm_domains driver, which must also call PM_INIT_FINALIZE. Due to the behavior of the PMU FW, all devices must be powered up before PM_INIT_FINALIZE is called, because otherwise the devices might misbehave. Calling PM_INIT_FINALIZE from the sync_state device callback ensures that all users probed successfully before the PMU FW is allowed to power off unused domains. Signed-off-by:
