Subject: OMAP: DSS2: move dss device clock configuration

Clock configuration was defined inside dssdev.phy.dsi struct. The clock
config doesn't really belong there, and so it's moved to dssdev.clock
struct.

Now the explicit clock configuration could also be used for other
interfaces than DSI, although there's no support for it currently.

Subject: OMAP: DSS2: DSI: add option to leave DSI lanes powered on

The DSI pins are powered by VDDS_DSI. If VDDS_DSI is off, the DSI pins
are floating even if they are pinmuxed to, say, safe mode and there's a
pull down/up.

This patch gives the panel drivers an option to leave the VDDS_DSI power
enabled while the DSS itself is turned off. This can be used to keep the
DSI lanes in a valid state while DSS is off, if the DSI pins are muxed
for pull down (not done in this patch).

There will be a slight power consumption increase (~100 uA?) when the
VDDS_DSI is left on, but because this option is used when the panel is
left on, the regulator consumption is negligible compared to panel power
consumption.

When the panel is fully turned off the VDDS_DSI is also turned off.

As an added bonus this will give us faster start up time when starting
up the DSS and the regulator is already enabled.

Subject: OMAP: DSS2: DSI: add parameter to enter ulps on disable

Add parameter to omapdss_dsi_display_disable() which the panel driver
can use to tell if the DSI lanes should be put to ULPS before disabling
the interface.

This can be used to skip ULPS entry in cases where the panel doesn't
care about ULPS state, for example when the panel will be reset, or when
the display interface will be enabled again right after the disable.

This will speed up the operation considerably in cases where entering
ULPS would fail with timeout, and the panel driver isn't even interested
in entering ULPS.

Subject: OMAP: DSS2: Taal: Implement ULPS functionality

ULPS is a low power state where the DSI lanes are kept at ground. This
patch implements ULPS by having a DSI bus inactivity timer which
triggers the entry to ULPS. ULPS exit will happen automatically when the
driver needs to do something on the DSI lanes.

The ulps_timeout is configurable from board file or via sysfs.
Additionally another sysfs file, "ulps", can be used to check the
current ULPS state, or to manually enter or exit ULPS.

Subject: OMAP: DSS2: DSI: Add extra omap_dss_device argument in functions
 exported by dsi

Add pointer to omap_dss_device struct as an argument in the functions which
are exported to dsi panel drivers. This argument will tell the DSI driver
which DSI interface's data it has to choose.

Subject: OMAP: DSS2: Pass platform_device as an argument in dsi functions

The DSI interface is represented as a platform device, using the DSI platform
driver(dsi.c). The current DSI driver design is capable of running only one
instance of a DSI device. On OMAP4, there are 2 very similar DSI modules which
can be represented as instances of "omapdss_dsi" platform device.

Add member "module" in "dssdev.phy.dsi" that tells us which DSI module's lanes
the panel is connected to. Modify dsi.c functions to take the device's
platform_device struct pointer, provide functions dsi_get_dsidev_from_dssdev()
and dsi_get_dsidev_from_id() take the panel's omap_dss_device and module number
respectively, and return the platform_device pointer. Currently, the dsi struct
is declared globally and is accessed when dsi data is needed. The new pdev
argument will be used later to provide the platform device's dsi related data.

Introduce DSI2 PLL clock sources needed by LCD2 channel and DSI2 Protocol
engine and DISPC Functional clock. Do the following:

- Modify dss_get_dsi_clk_source() and dss_select_dsi_clk_source() to take the
  dsi module number as an argument.
- Create debugfs files for dsi2, split the corresponding debugfs functions.
- Allow DPI to use these new clock sources.

Subject: OMAP: DSS2: DSI: Get number of DSI data lanes using DSI_GNQ register

On OMAP3, the DSI module has 2 data lanes. On OMAP4, DSI1 has 4 data lanes
and DSI2 has 2 data lanes. Introduce function dsi_get_num_data_lanes() which
returns the number of data lanes on the dsi interface, introduce function
dsi_get_num_data_lanes_dssdev() which returns the number of data lanes used by
the omap_dss_device connected to the lanes.

Use the DSI_GNQ register on OMAP4 to get the number of data lanes, modify
dsi.c to use the number of lanes and the extra data lanes on DSI1.

Subject: OMAP: DSS2: Add support for NV12 format

Add the support for NV12 color format.
Configure base address for UV component of NV12 color format.
Change the way chroma scaling is handled for YUV formats on OMAP4 by enabling
chroma-resampling for video pipeline and hence using FIR2 register set for
scaling UV.
Changes to _dispc_set_scaling(), because of the reason above, are:
- call _dispc_set_scaling_common() to handle scaling for all color formats
  except for OMAP4 where it only handles scaling for RGB or Y-component
- call _dispc_set_scaling_uv() for special handling required for UV
  component on OMAP4.
- dispc_set_scaling_uv() also resets chroma-resampling bit for RGB color modes.

Contains chroma scaling (_dispc_set_scaling_uv) design and implemented by
Lajos Molnar <molnar@ti.com>
