From 4b3706607c0015ba99a86d8631446564c117e06a Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Thu, 18 Apr 2024 12:58:28 -0500 Subject: [PATCH] arm: mach-k3: am642: Fix reset for workaround errata ID i2331 To workaround an issue in AM642 we reset the SoC in early boot. For that we first probed the sysreset driver by calling uclass_get_device(). The ti-sci sysreset driver is now probed during the ti-sci firmware probe. Update this call to probe the firmware driver which will then probe the sysreset driver allowing do_reset() to again function as expected.
