From bb318d8dc801586b5e587f7f7d508ad54022fb4b Mon Sep 17 00:00:00 2001 From: Tero Kristo Date: Fri, 11 Jun 2021 11:45:27 +0300 Subject: [PATCH] arm: dts: k3-j72xx: correct MCU timer1 frequency MCU timer1 is used as the tick timer for MCU R5 SPL, and the clock-frequency defined in DT appears to be incorrect at the moment. Actual clock source for the timer is MCU_SYSCLK0 / 4 which is 250MHz. Earlier setup of 25MHz went unnoticed, as there was a separate issue with omap-timer, which caused an error to the clock by a factor of 8 with j7 devices. This problem surfaced once the omap-timer was fixed.
