From: Alexander Dahl Date: Wed, 21 Aug 2024 05:51:36 +0000 (+0200) Subject: ARM: dts: microchip: sam9x60: Fix rtc/rtt clocks X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d355c895fa4ddd8bec15569eee540baeed7df8c5;p=linux.git ARM: dts: microchip: sam9x60: Fix rtc/rtt clocks The RTC and RTT peripherals use the timing domain slow clock (TD_SLCK), sourced from the 32.768 kHz crystal oscillator or slow rc oscillator. The previously used 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.
