Subject[PATCH 5.3 018/135] arm64: dts: ls1028a: fix a compatible issue
Date
From: Yuantian Tang <andy.tang@nxp.com>

[ Upstream commit 7eb3894b2fac978f811684e3ccb3cb0ad7820bef ]

The I2C multiplexer used on ls1028aqds is PCA9547, not PCA9847.
If the wrong compatible was used, this chip will not be able to
be probed correctly and hence fail to work.
