Subject: [PATCH 15/17] can: xilinx_can: Limit CANFD brp to 2
Date: Wed, 7 Oct 2020 23:31:57 +0200 [thread overview]
Message-ID: <20201007213159.1959308-16-mkl@pengutronix.de> (raw)
In-Reply-To: <20201007213159.1959308-1-mkl@pengutronix.de>
From: Srinivas Neeli <srinivas.neeli@xilinx.com>
Bit enlarging is observed for CANFD2.0 when brp is 1,
So change brp_min value to 2.
