Subject: [U-Boot] [PATCH v3 4/6] video: fsl_dcu_fb: Fix DCU_MODE_BLEND_ITER setting
Date: Tue, 11 Apr 2017 11:12:12 +0530 [thread overview]
Message-ID: <6676f08c219465c71d82d7530cf27edae682536c.1491887884.git.maitysanchayan@gmail.com> (raw)
In-Reply-To: <cover.1491887884.git.maitysanchayan@gmail.com>
From: Stefan Agner <stefan.agner@toradex.com>
DCU_LAYER_MAX_NUM is currently used for DCU_MODE_BLEND_ITER and it
actually overflows the maximum value of BLEND_ITER for Vybrid and
LS102XA. Fix this by using a default value of 2.
