Part Number: AM625
I am using the ti-linux-5.10.y branch of git.ti.com/git/ti-linux-kernel/ti-linux-kernel.git. The board is a custom board with a HS-SE AM625.
The AM62x main device tree (arch/arm64/boot/dts/ti/k3-am62-main.dtsi) has the following for the crypto module:
crypto: crypto@40900000 { compatible = "ti,am62-sa3ul"; reg = <0x00 0x40900000 0x00 0x1200>; power-domains = <&k3_pds 70 TI_SCI_PD_SHARED>; #address-cells = <2>; #size-cells = <2>; ranges = <0x00 0x40900000 0x00 0x40900000 0x00 0x30000>;
dmas = <&main_pktdma 0xf501 0>, <&main_pktdma 0x7506 0>, <&main_pktdma 0x7507 0>; dma-names = "tx", "rx1", "rx2";
Note the power domain. At boot, attempts to start the driver fail because the power domain can not be enabled.
ti_sci_pd_power_on() tries to enable the domain named pd:70. The results in a mailbox call by ti_sci_set_device_state() / ti_sci_do_xfer(). The mailbox call gets a response, but the flags are 0 which is a NACK.
Is that the right power domain for crypto?
If so, why can it not be enabled?
I note that crypto@40900000 for the AM62A (k3-am62a-main.dtsi) does not indicate any power domain. Is one actually required for the AM625?
Other k3_pds power domains are being enabled through the mailbox without issue, such as pd:102 (main_i2c0) and pd:98 (main_mcan0).

Steve
