Subject: [PATCH v3 17/27] omap: timer: fix the rate setting
Date: Sun, 11 Oct 2020 14:13:30 +0200 [thread overview]
Message-ID: <20201011121340.21660-18-dariobin@libero.it> (raw)
In-Reply-To: <20201011121340.21660-1-dariobin@libero.it>
The prescaler (PTV) setting must be taken into account even when the
timer input clock frequency has been set.
