Subject: [PATCH v7 09/15] can: grcan: Add saving and restoring of CAN FD baud-rate registers
Date: Fri,  8 May 2026 09:01:15 +0200	[thread overview]
Message-ID: <20260508070121.6918-10-arun.muthusamy@gaisler.com> (raw)
In-Reply-To: <20260508070121.6918-1-arun.muthusamy@gaisler.com>

From: Daniel Hellstrom <daniel@gaisler.com>

While reset the GRCAN baud-rates are preserved, since GRCANFD has the
baud-rate in different registers we need to add saving of those
registers too.
