From: Sumit Semwal <sumit.semwal@ti.com>
On OMAP4, we have a new DISPC channel for Overlay Manager LCD2. 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.
Introduce new enum members for LCD2 Channel and corresponding Overlay Manager
in display.h.
Represent the following DISPC register defines with channel as a parameter
to differentiate between LCD and LCD2 registers (and also DIGIT in some cases):
DISPC_DEFAULT_COLOR, DISPC_TRANS_COLOR, DISPC_TIMING_H, DISPC_TIMING_V,
DISPC_POL_FREQ, DISPC_DIVISOR, DISPC_SIZE_LCD, DISPC_DATA_CYCLEk,
DISPC_CPR_COEF_R, DISPC_CPR_COEF_G and DISPC_CPR_COEF_B
This parametrization helps in reducing the number of register defines for DISPC.
Replace the existing reads/writes to these registers in this new way.
Also, Introduce defines for registers DISPC_CONTROL2 and DISPC_CONFIG2 which
are used exclusively for LCD2 channel.

Cc: linux-omap, Sumit Semwal, Mukund Mittal, Samreen, Archit Taneja
From: Sumit Semwal <sumit.semwal@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()

From: Sumit Semwal <sumit.semwal@ti.com>
DISPC functions are modified in order to work when the manager is LCD2.
This includes:
Adding new IRQs specific to LCD2 and their handling.
Provide dumps of the new manager's registers.
Provide dumps of the new manager's clocks.
Checks for channel for registers DISPC_CONTROL2 and DISPC_CONFIG2
which can't be parametrized.

To: tomi.valkeinen; +Cc: linux-omap, Sumit Semwal, Mukund Mittal, Samreen
From: Sumit Semwal <sumit.semwal@ti.com>
A panel connects to one of the overlay managers of DSS through some interface block.
On OMAP4, specifying the type of the display is not sufficient to conclude which manager
the panel should be connected to.
Hence, a new member 'channel' is introduced in omap_dss_device structure to determine
which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe()
uses this channel parameter to set the correct manager to the corresponding omap_dss_device.
The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.
Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.
