From: Sumit Semwal <sumit.sem...@ti.com>
The interface drivers (dsi.c, sdi.c etc) need to call dispc functions with
dssdev->manager->id as a parameter to specify the DISPC channel which they want
to configure/use, this is required as the same functions are now used to
configure
dispc registers of different channels.
The following dispc functions are changed to incorporate channel as an argument:
-dispc_enable_fifohandcheck()
-dispc_set_lcd_size()
-dispc_set_parallel_interface_mode()
-dispc_set_tft_data_lines()
-dispc_set_lcd_display_type()
-dispc_set_lcd_timings()
