Subject: [PATCH 4.20 74/88] mmc: sdhci-esdhc-imx: correct the fix of ERR004536
Date: Mon, 4 Mar 2019 09:22:57 +0100 [thread overview]
Message-ID: <20190304081633.563038513@linuxfoundation.org> (raw)
In-Reply-To: <20190304081630.610632175@linuxfoundation.org>
4.20-stable review patch. If anyone has any objections, please let me know.
------------------
From: BOUGH CHEN <haibo.chen@nxp.com>
commit e30be063d6dbcc0f18b1eb25fa709fdef89201fb upstream.
Commit 18094430d6b5 ("mmc: sdhci-esdhc-imx: add ADMA Length
Mismatch errata fix") involve the fix of ERR004536, but the
fix is incorrect. Double confirm with IC, need to clear the
bit 7 of register 0x6c rather than set this bit 7.
Here is the definition of bit 7 of 0x6c:
0: enable the new IC fix for ERR004536
1: do not use the IC fix, keep the same as before
Find this issue on i.MX845s-evk board when enable CMDQ, and
let system in heavy loading.
