Subject: [PATCH v7 1/6] media: i2c: max9286: Disable overlap window
Date: Sun, 16 Feb 2020 11:51:00 +0100 [thread overview]
Message-ID: <20200216105105.3751688-2-jacopo+renesas@jmondi.org> (raw)
In-Reply-To: <20200216105105.3751688-1-jacopo+renesas@jmondi.org>
Disable the overlap window. This settings is briefly documented in the
chip manual, but it probably concur in the frame syncronization timing
calculations.
