Subject: [PATCH] mfd: pca9450: print reset reason as hex if unknown
Date: Thu, 2 May 2024 12:17:24 +0200 [thread overview]
Message-ID: <20240502101724.2609941-1-a.fatoum@pengutronix.de> (raw)
On an i.MX93-based board, it was observed that a potential ELE-induced
reset ended up with an unknown reset reason. To aid in debugging this,
print the value in hexadecimal when no mapping is known.
