[PATCH v3 0/2] Remove power-domains property for devices with compatible ti,am62-sa3ul

[Kamlesh Gurudasani]

SYSFW don't allow access to power of devices with compatible ti,am62-sa3ul
from main domain.

Power-domains property, if present will try to access the power of the
device, which will result into failure in probing of driver for that
device.

Make power-domains property as false for devices with compatible
ti,am62-sa3ul.

[PATCH v3 1/2] dt-bindings: crypto: ti,sa2ul: make power-domains conditional

[Kamlesh Gurudasani]

Devices specific to compatible ti,am62-sa3ul don't have control over
power of SA3UL from main domain.

"power-domains" property in crypto node tries to access
the SA3UL power, for which it gets NACK and hence, driver doesn't
probe properly for those particular devices.

Make "power-domains" property as false for devices with
compatible ti,am62-sa3ul.

[PATCH v3 2/2] arm64: dts: ti: k3-am62-main: Remove power-domains from crypto node

[Kamlesh Gurudasani]

Only SYSFW has control of SA3UL power.
From SYSFW 08.04.00.002, for security reasons, device ID for power
management of SA3UL has been removed.

"power-domains" property in crypto node tries to access
the SA3UL, for which it gets NACK and hence, SA3UL driver doesn't
probe properly.
