Subject: [PATCH AUTOSEL 5.18 32/41] Revert "can: xilinx_can: Limit CANFD brp to 2"
Date: Thu, 14 Jul 2022 00:22:12 -0400 [thread overview]
Message-ID: <20220714042221.281187-32-sashal@kernel.org> (raw)
In-Reply-To: <20220714042221.281187-1-sashal@kernel.org>
From: Srinivas Neeli <srinivas.neeli@xilinx.com>
[ Upstream commit c6da4590fe819dfe28a4f8037a8dc1e056542fb4 ]
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.
