So, no, I didn't test, sorry! List of Patches: 0001: is required to call "init_fw" API, for SoC i.XM9x. 0002: i.MX93 do not have CAAM, ELE's RNG needs to be started, post init_fw. 0003: iMX93 do not have CAAM, hence (T)RNG & hwrng, need to enabled via ELE. 0004: enforce message sequence flow to prevent any message exchange out of sequence. Required by power management API(s). 0005: additional API(s) required by Linux kernel management layers like NVMEM & power management. 0006: EXPORTED API to be used by other kernel management layers. 0007 & 0008: are DTSI & DTS changes. 1. If you add DTSI & DTS changes, i.MX93 board will come up with driver successfully probed.

If you want to use ELE test, you need to apply patches: 0001 & 0002.
