imx: imx8qm/imx8qxp: Power down the resources before SPL jump to u-boot

2020-05-10T18:55:20Z

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

imx8: Replace SC_R_LAST with SC_R_NONE in DTB

2020-05-10T18:55:20Z

We are currently using SC_R_LAST as a marker for imx8 power domain tree nodes without a resource attached. This value is compiled into dtb as part of the linux build and used by uboot. The SC_R_LAST constant changes frequently as SCFW resources are added (by design) and every time we need to update linux and uboot headers together or boot can fail. Fix this by replacing SC_R_LAST usage with a new constant SC_R_NONE defined to be 0xFFF0. Reviewed-by: Peng Fan Signed-off-by: Leonard Crestez Signed-off-by: Peng Fan

power: imx8: Check owned resource in power on

2020-05-10T18:55:20Z

When fspi is assigned to M4, we have to let the fspi probe failed when its power domain is failed to power up. Because not all devices have power domain (for example, external devices on the board). Current checking resource owner in power domain probe is not good, change to check it in power on. Signed-off-by: Ye Li Signed-off-by: Peng Fan

power: imx8: remove the resource owned check before power off

2020-05-10T18:55:20Z

For all the devices used and set ACTIVE in U-Boot, U-Boot needs to power off all of them without the check of resource owner. When we create software partition before booting Linux, the resource own checkw will return false, and cause the power domain not powered off. If without the check of resource owner, the power domain in the other software partition could be powered off with parent partition could access child partition resources. Signed-off-by: Peng Fan

power: imx8-power-domain: Set DM_FLAG_DEFAULT_PD_CTRL_OFF flag

2020-05-10T18:55:20Z

If without this flag, calling dev_power_domain_ctrl will iteratively remove the power domain device will causes iteratively power off parent PD. This is not expected by imx8-power-domain-legacy driver. Power off parent PD is controlled by the driver internally. So set DM_FLAG_DEFAULT_PD_CTRL_OFF to avoid such issue Signed-off-by: Ye Li Signed-off-by: Peng Fan

imx8: power: Add PD device lookup interface to power domain uclass

2020-05-10T18:55:20Z

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. Signed-off-by: Ye Li Signed-off-by: Peng Fan

pmic: pfuze100: Change error message level to debug

2020-04-18T10:59:37Z

In some cases U-Boot runs the same binary on different board versions. In wandboard, for example, there are versions with the PFUZE100 PMIC populated and others without it. When the PMIC is not present, it is not really useful to get PMIC error, so change the error message level to debug instead. Signed-off-by: Fabio Estevam Tested-by: Heiko Schocher

x86: Move acpi_s3.h to include/acpi/

2020-04-16T06:36:28Z

This header relates to ACPI and we are about to add some more ACPI headers. Move this one into a new directory so they are together. The header inclusion in pci_rom.c is not specific to x86 anymore, so drop the #ifdef CONFIG_X86.
