2020-05-10imx: imx8qm/qxp: check whether m4 partition bootedPeng Fan1-0/+1

2020-05-10imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-bootPeng Fan1-0/+1
Make sure that all devices that are powered up by SPL are powered down before entering into the u-boot. Otherwise the subsystem/device will never be powered down by SCFW, due to SPL and u-boot are in different partitions. Benefiting from power domain driver, this patch implements the function "imx8_power_off_pd_devices" to power off all active devices. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10imx8: power: Add PD device lookup interface to power domain uclassPeng Fan1-0/+7
Add power_domain_lookup_name interface to power domain uclass to find a power domain device by its DTB node name, not using its associated client device. Through this interface, we can operate the power domain devices directly. This is needed for non-DM drivers. Modified from Ye's NXP downstream patch only for legacy imx8 power domain driver, since we have not migrated to use new power domain driver.
