Subject: [PATCH 1/2] ARM: dts: am335x-myirtech: Add an external clock oscillator for CPU RTC
Date: Wed, 27 Apr 2022 11:19:13 +0300	[thread overview]
Message-ID: <20220427081914.6773-1-eagle.alexander923@gmail.com> (raw)

The CPU RTC has an external crystal, so to keep time, let's define
it for devicetree.
