Subject: [PATCHv3 26/26] arm: dts: k3-j72xx: correct MCU timer1 frequency
Date: Wed, 5 May 2021 20:55:40 +0300 [thread overview]
Message-ID: <20210505175540.15006-27-kristo@kernel.org> (raw)
In-Reply-To: <20210505175540.15006-1-kristo@kernel.org>
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.
