Subject: [PATCH 6/6] can: flexcan: fix ECC function on LS1021A/LX2160A
Date: Fri, 16 Oct 2020 21:43:20 +0800	[thread overview]
Message-ID: <20201016134320.20321-7-qiangqing.zhang@nxp.com> (raw)
In-Reply-To: <20201016134320.20321-1-qiangqing.zhang@nxp.com>

After double check with Layerscape CAN owner (Pankaj Bansal), confirm
that LS1021A doesn't support ECC, and LX2160A indeed supports ECC.

For SoCs with ECC supported, even use FLEXCAN_QUIRK_DISABLE_MECR quirk to
disable non-correctable errors interrupt and freeze mode, had better use
FLEXCAN_QUIRK_SUPPORT_ECC quirk to initialize all memory.
