Subject: [cip-dev] [PATCH 4.19.y 12/29] media: rcar-csi2: Fix PHTW table values for E3/V3M
Date: Wed,  1 May 2019 11:22:06 +0100	[thread overview]
Message-ID: <1556706143-11898-13-git-send-email-fabrizio.castro@bp.renesas.com> (raw)
In-Reply-To: <1556706143-11898-1-git-send-email-fabrizio.castro@bp.renesas.com>

From: Jacopo Mondi <jacopo+renesas@jmondi.org>

commit aa8a1012ba624e92fd1ab58463f22501bce78af8 upstream.

The PHTW selection algorithm implemented in rcsi2_phtw_write_mbps() checks for
lower bound of the interval used to match the desired bandwidth. Use that
in place of the currently used upper bound.

Fixes: 10c08812fe60 ("media: rcar: rcar-csi2: Update V3M/E3 PHTW tables")
