c6b393d4bc OMAPDSS: DPI: Maintain copy of number of data lines in driver data
The DPI driver currently relies on the omap_dss_device struct to configure the
number of data lines as specified by the panel. This makes the DPI interface
driver dependent on the omap_dss_device struct.

Make the DPI driver data maintain it's own data lines field. A panel driver
is expected to call omapdss_dpi_set_data_lines() before enabling the interface.

bdcae3cc39 OMAPDSS: DPI displays: Take care of panel timings in the driver itself
The timings maintained in omap_dss_device(dssdev->panel.timings) should be
maintained by the panel driver itself. It's the panel drivers responsibility
to update it if a new set of timings is to be configured. The DPI interface
driver shouldn't be responsible of updating the panel timings, it's responsible
of maintianing it's own copy of timings.

c499144c3b OMAPDSS: DPI: Maintain our own timings field in driver data
The DPI driver currently relies on the timings in omap_dss_device struct to
configure the DISPC accordingly. This makes the DPI interface driver dependent
on the omap_dss_device struct.

Make the DPI driver data maintain it's own timings field. The panel driver is
expected to call dpi_set_timings()(renamed to omapdss_dpi_set_timings) to set
these timings before the panel is enabled.

In the set_timings() op, we still ensure that the omap_dss_device timings
(dssdev->panel.timings) are configured. This will later be configured only by
the DPI panel drivers.

e19d659bbf OMAPDSS: Displays: Add locking in generic DPI panel driver
The generic DPI panel driver doesn't currently have locking to ensure that
the display states and the driver data is maintained correctly. Add mutex
locking to take care of this. Add a new get_timings driver op to override the
default get_timings op. The new driver op contains locking to ensure the correct
panel timings are seen when a DSS2 user calls device->driver->get_timings.

07fb51c6bd OMAPDSS: Remove omap_panel_config enum from omap_dss_device
omap_panel_config contains fields which are finally written to DISPC_POL_FREQo
registers. These are now held by omap_video_timings and are set when the manager
timings are applied.

Remove the omap_panel_config enum, and remove all it's references from panel or
interface drivers.

a8d5e41cef OMAPDSS: Add some new fields to omap_video_timings
Some panel timing related fields are contained in omap_panel_config in the form
of flags. The fields are:

- Hsync logic level
- Vsync logic level
- Data driven on rising/falling edge of pixel clock
- Output enable/Data enable logic level
- HSYNC/VSYNC driven on rising/falling edge of pixel clock

Out of these parameters, Hsync and Vsync logic levels are a part of the timings
in the Xorg modeline configuration. So it makes sense to move the to
omap_video_timings. The rest aren't a part of modeline, but it still makes
sense to move these since they are related to panel timings.

These fields stored in omap_panel_config in dssdev are configured for LCD
panels, and the corresponding LCD managers in the DISPC_POL_FREQo registers.

Add the above fields in omap_video_timings. Represent their state via new enums.

Add these parameters to the omap_video_timings instances in the panel drivers.
Keep the corresponding IVS, IHS, IPC, IEO, RF and ONOFF flags in
omap_panel_config for now. The struct will be removed later.

a9105cb5c2 OMAPDSS: Remove passive matrix LCD support (part 4)
Remove configuration of Ac-bias pins

Ac-bias pins need to be configured only for passive matrix displays. Remove
acbi and acb fields in omap_dss_device and their configuration in panel
drivers. Don't program these fields in DISP_POL_FREQo register any more.

The panel driver for sharp-ls037v7dw01, and the panel config for
Innolux AT070TN8 in generic dpi panel driver set acb to a non zero value. This
is most likely carried over from the old omapfb driver which supported passive
matrix displays.
