Subject: [PATCH] ARM: dts: microchip: sam9x60: Fix rtc/rtt clock parent
Date: Tue, 20 Aug 2024 15:27:30 +0200	[thread overview]
Message-ID: <20240820132730.357347-1-ada@thorsis.com> (raw)

The RTC and RTT peripherals use the "timing domain slow clock (TD_SLCK),
sourced from the 32.768 kHz crystal oscillator.

(The Monitoring domain slow clock (MD_SLCK) is sourced from an internal
RC oscillator which is most probably not precise enough for real time
clock purposes.)

Fixes: 1e5f532c2737 ("ARM: dts: at91: sam9x60: add device tree for soc and board")
Fixes: 5f6b33f46346 ("ARM: dts: sam9x60: add rtt")
