From 59dacc319030748817b28cce9c773e15f2b73dc8 Mon Sep 17 00:00:00 2001 From: Patrick Delaunay Date: Thu, 15 Dec 2022 09:54:52 +0100 Subject: [PATCH] optee: bind the TA drivers on OP-TEE node In U-Boot driver model the devices can be referenced by phandle in the U-Boot configuration nodes. Without a valid node provided during the bind, the driver associated to OP-TEE TA can't be referenced. For example to force the sequence number with alias (.flags = DM_UC_FLAG_SEQ_ALIAS) aliases { rng0 = &optee; }; or other configuration: board-sysinfo { compatible = "vendor,sysinfo-board"; ramdom = <&optee>; } With this patch all drivers bound from OP-TEE service discovery are now associated are associated to OP-TEE node, allowing to identify by phandle the driver provided by the TA for one UCLASS without modifying device tree.
