From 5ee3c1445dd89342ca8498c14afef82d0f76c794 Mon Sep 17 00:00:00 2001 From: Archit Taneja Date: Wed, 2 Mar 2011 12:35:53 +0530 Subject: OMAP: DSS2: Functions to request/release DSI VCs Introduce functions which request and release VC's. This will be used in panel drivers in their probes. omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID parameter which goes into the header of the DSI packets, and returns a Virtual channel number (or virtual channel register set) which it can use. omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel number and the VC_ID that needs to be set for the specifed Virtual Channel. omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel number that needs to be made free. Initialisation of VC parameters is done in dsi_init().
