[PATCH 2/2] arm64: dts: microchip: sparx5: use correct clock for tmon
From: Robert Marko
Date: Tue Aug 09 2022 - 07:22:29 EST
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.
