Subject: [PATCH 2/4] ARM STM/i.MX: Add possibility to choose the bit per pixel for STM video driver
Date: Tue, 04 Jan 2011 15:35:27 +0100 [thread overview]
Message-ID: <4D23302F.5070109@free-electrons.com> (raw)
When describing an new video interface, it is now possible to select
the bit per pixel. If nothing is chosen 16bpp is selected by default.
