Subject: [PATCH V2 1/2] Revert "can: xilinx_can: Limit CANFD brp to 2"
Date: Tue, 7 Jun 2022 14:26:53 +0530 [thread overview]
Message-ID: <20220607085654.4178-2-srinivas.neeli@xilinx.com> (raw)
In-Reply-To: <20220607085654.4178-1-srinivas.neeli@xilinx.com>
This reverts commit 05ca14fdb6fe65614e0652d03e44b02748d25af7.
On early silicon engineering samples observed
bit shrinking issue when we use brp as 1.
Hence updated brp_min as 2. As in production
silicon this issue is fixed,so reverting the patch.
