2020-05-10imx: imx8qm/qxp: check whether m4 partition bootedPeng Fan
Add code to check m4 partition booted or not, we will use this to runtime set device tree file that passed to Linux Kernel. Signed-off-by: Peng Fan <peng.fan@nxp.com>
2020-05-10imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-bootPeng Fan
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 Fan
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.
