[PATCH 1/1] arm64: dts: lx2160a: Fix DTS for full PL011 UART

Frank Li Frank.Li at nxp.com
Tue Feb 6 15:15:21 PST 2024


From: Heinz Wrobel <Heinz.Wrobel at nxp.com>

The prior configuration was an SBSA UART that can't be configured or
modified, or even enabled if it isn't the boot console. With properly
defined clocks, the PL011 configuration can be used.
