From: Semwal, Sumit <sumit.semwal@xxxxxx> This patch series incorporates changes in DSS2 to enable omap_dss_device instances to use the new Overlay Manager LCD2 in DISPC. 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.
