Subject: [PATCH 2/2] arm64: dts: microchip: sparx5: use correct clock for tmon
Date:   Tue,  9 Aug 2022 13:22:09 +0200

SparX-5 temperature sensor uses system reference clock and not the AHB bus
clock as indicated by the register information [1].

Configured number of system clock cycles in one 1us is now almost spot on
to the default register value.
