[PATCH 5.13 141/156] ARM: dts: tacoma: Add phase corrections for eMMC
From: Greg Kroah-Hartman
Date: Thu Jul 22 2021 - 12:54:20 EST
From: Andrew Jeffery <andrew@xxxxxxxx>
commit 2d6608b57c50c54c3e46649110e8ea5a40959c30 upstream.
The degree values were reversed out from the magic tap values of 7 (in)
and 15 + inversion (out) initially suggested by Aspeed.
With the patch tacoma survives several gigabytes of reads and writes
using dd while without it locks up randomly during the boot process.
