[PATCH] ARM: dts: tacoma: Add phase corrections for eMMC

From: Andrew Jeffery
Date: Fri Jun 25 2021 - 02:10:42 EST


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.
