Subject: [PATCH v5 1/5] media: dt-bindings: media: i2c: Deprecate usage of the clock-frequency property
Date: Mon, 6 Apr 2020 17:42:37 +0100 [thread overview]
Message-ID: <1586191361-16598-2-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <1586191361-16598-1-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com>
OV5645 sensor supports input clock frequency ranging from 6MHz to 27MHz
but the driver strictly expects this to be 24MHz (with tolerance of 1%)
with this restrictions let the driver enforce the clock frequency
internally to 24MHz rather then being passed as dt-property.
