Subject: [PATCH 03/20] can: flexcan: more register names
Date: Tue, 22 Sep 2020 16:44:12 +0200	[thread overview]
Message-ID: <20200922144429.2613631-4-mkl@pengutronix.de> (raw)
In-Reply-To: <20200922144429.2613631-1-mkl@pengutronix.de>

This patch adds some new register names and tries to ensure with a
static_assert that the documented offset is correct.
