Subject: [PATCH v2 1/4] i3c: dw: make resets optional in probe
Date: Thu, 9 Jul 2026 14:42:52 +0530	[thread overview]
Message-ID: <20260709091357.1860417-2-pranav.vinaytilak@amd.com> (raw)
In-Reply-To: <20260709091357.1860417-1-pranav.vinaytilak@amd.com>

Treat -ENOENT and -ENOTSUPP from reset_get_bulk() as non-fatal to
support platforms where no resets are defined in the DTS. The resets
property is not yet documented in the DT binding.

Fixes: 1009c96f1590 ("drivers: i3c: Add driver for MIPI DWI3C")
