The PIXDATA flags of the display_flags enum are controller centric, e.g. NEGEDGE means the controller shall drive the data signals on pixelclocks negative edge. However, the drivers flag is display centric: Sample the data on negative (falling) edge. Therefore, change the if statement to check for the POSEDGE flag (which is typically not set): Drive on positive edge => sample on negative edge Signed-off-by: Stefan Agner <stefan@agner.ch> Acked-by: Shawn Guo <shawnguo@kernel.org> Cc: Jean-Christophe Plagniol-Villard <plagnioj@jcrosoft.com> Cc: Sascha Hauer <s.hauer@pengutronix.de> Cc: Liu Ying <Ying.Liu@freescale.com> Cc: Lothar Waßmann <LW@KARO-electronics.de> Cc: Fabio Estevam <fabio.estevam@freescale.com> Cc: Max Krummenacher <max.krummenacher@toradex.com> Cc: Mauro Salvini <mauro.salvini@smigroup.net> Signed-off-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
