[PATCH v6 12/12] arm64: dts: nuvoton: ma35d1: Add LXT crystal and clock-names
COOLING4d
From: Miquel Raynal <miquel.raynal@bootlin.com>

arm/nuvoton ma35 architecture, arm/nuvoton npcm architecture, the rest · Maintainers:

The clock controller takes its two crystal oscillator inputs from the
board: HXT and LXT. The LXT crystal is not described at all: add the
fixed clock node for it and reference both inputs from the clock
controller node, with their respective clock-names.
