On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. This channel's video port is a source port for RFBI, DSI2 and DPI. The Primary channel's video port is connected to RFBI and DSI1. There is a set of regsiters for LCD2 channel similar to the existing LCD channel, like DISPC_CONTROL2, DISPC_DIVISOR2, DISPC_CONFIG2 and so on. In order to decide which LCD Overlay Manager to configure(LCD/LCD2), there is a need for the omap_dss_device instances to tell the interface drivers(DSI, DPI, RFBI etc) which LCD channel they want to connect to, so that the corresponding registers get configured. Therefore, a new enum omap_channel member is introduced to omap_dss_device. This design was made keeping in mind the possible addition of more Overlay Managers in future OMAPs, this code is also backward compatible with OMAP3 as omap_dss_device instances in OMAP3 will stick only with OMAP_DSS_CHANNEL_LCD. This will apply over the set of dss_feature framework patches: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg34768.html Archit Taneja (1): OMAP: DSS2: Add dss_features for omap4 and new overlay manager level features Sumit Semwal (3): OMAP: DSS2: Incorporate Secondary LCD Channel DISPC Registers OMAP: DSS2: Interface driver changes for Secondary LCD Channel OMAP: DSS2: Add new Overlay Manager arch/arm/plat-omap/include/plat/display.h | 7 + drivers/video/omap2/dss/core.c | 2 +- drivers/video/omap2/dss/dispc.c | 627 +++++++++++++++++++---------- drivers/video/omap2/dss/dpi.c | 38 +- drivers/video/omap2/dss/dsi.c | 24 +- drivers/video/omap2/dss/dss.h | 39 ++- drivers/video/omap2/dss/dss_features.c | 39 ++- drivers/video/omap2/dss/dss_features.h | 7 +- drivers/video/omap2/dss/manager.c | 73 +++-- drivers/video/omap2/dss/overlay.c | 14 +- drivers/video/omap2/dss/rfbi.c | 21 +- drivers/video/omap2/dss/sdi.c | 22 +- 12 files changed, 604 insertions(+), 309 deletions(-) -- Version 3: - Patches are reworked over dss2 features framework. Number of patches are reduced. Version 2: - The DISPC_BASE macro now isn't changed for OMAP4, a future hwmod patch will take care of this dynamically. - Supported_displays member of manager is now assigned correctly for OMAP2. - DISPC Registers common to LCD and LCD2 channels are not defined separately, now there is a parameter which differentiates between the 2 channels. - Secondary LCD manager is now named as lcd2 instead of 2lcd, the patch given in the link below allows DSS2 interpret this correctly. http://www.mail-archive.com/linux-omap@vger.kernel.org/msg31714.html Version 1: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg31458.html
