From cfb4f5d1750e05f43902197713c50c29e7dfbc99 Mon Sep 17 00:00:00 2001 From: Magnus Damm Date: Wed, 23 Jul 2008 21:31:24 -0700 Subject: fbdev: SuperH Mobile LCDC Driver This is the SuperH Mobile LCDC frame buffer driver V2, adding support for the LCDC block found in SuperH Mobile processors. The hardware supports up to two LCD panels per LCDC block, and both RGB and SYS interfaces can be used to hook up LCD panels/modules. The device driver is a regular platform driver, so LCD configuration and board specific hooks are passed to the driver using platform data. LCD modules using SYS interface often require special configuration using the SYS bus, and to solve this cleanly the driver provides SYS interface operations to the board code. Tested on sh7723 and sh7722 processors with a SYS16A QVGA panel and WVGA panels using RGB16 and RGB18 interfaces.
