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.
