OMAPDSS: fix regression with display sysfs files

2015-02-26T08:23:15+00:00

omapdss's sysfs directories for displays used to have 'name' file,
giving the name for the display. This file was later renamed to
'display_name' to avoid conflicts with i2c sysfs 'name' file. Looks like
at least xserver-xorg-video-omap3 requires the 'name' file to be
present.

To fix the regression, this patch creates new kobjects for each display,
allowing us to create sysfs directories for the displays. This way we
have the whole directory for omapdss, and there will be no sysfs file
clashes with the underlying display device's sysfs files.

We can thus add the 'name' sysfs file back.

OMAPDSS: DPI: DRA7xx support

2015-02-04T10:32:07+00:00

Add support for DRA7xx DPI output.

DRA7xx has three DPI outputs, each of which gets its input from a DISPC
channel. However, DRA72x has only one video PLL, and DRA74x has two
video PLLs. In both cases the video PLLs need to be shared between
multiple outputs. The driver doesn't handle this at the moment.

Also, DRA7xx requires configuring CONTROL module bits to route the clock
from the PLL to the used DISPC channel.

OMAPDSS: HDMI: Add DRA7xx support

2015-02-04T10:32:06+00:00

Add support for DRA7xx to the HDMI driver.

The HDMI block on DRA7xx is the same as on OMAP5, except we need to
enable and disable the HDMI PLL via the CONTROL module.

OMAPDSS: DISPC: program dispc polarities to control module

2015-02-04T10:32:06+00:00

On DRA7xx, DISPC needs to write output signal polarities not only to a
DISPC register, like for all earlier DSS versions, but to control
module's CTRL_CORE_SMA_SW_1 register.

This patch adds support to write the polarities to control module.

OMAPDSS: DISPC: Add DRA7xx support

2015-02-04T10:32:06+00:00

Add DRA7xx support to DISPC driver. The DISPC block is the same as on
OMAP5, except the PLL's used for clocking are "videoX", not "dsiX".

OMAPDSS: Add Video PLLs for DRA7xx

2015-02-04T10:32:05+00:00

DRA7xx SoCs have one (DRA72x) or two (DRA74x) video PLLs. They are
basically the same as DSI PLLs on OMAPs, but without the rest of the DSI
hardware. The video PLLs also require some configuration via the CONTROL
module.

OMAPDSS: Add functions for external control of PLL

2015-02-04T10:32:05+00:00

Add functions which configure the control module register
CTRL_CORE_DSS_PLL_CONTROL found in DRA7xx SoCs. This register configures
whether the PLL registers are accessed internally by DSS, or externally
using OCP2SCP interface. They also configure muxes which route the PLL
output to a particular LCD overlay manager within DSS.

OMAPDSS: DSS: Add DRA7xx base support

2015-02-04T10:32:05+00:00

Add base support for DRA7xx to DSS core.

OMAPDSS: OMAP5: fix digit output's allowed mgrs

2015-02-04T10:32:03+00:00

The OMAP5 HW supports directing DIGIT channel to DPI output, but the
driver doesn't support that. However, we have marked that configuration
as possible in the dss features, so in certain cases the driver tries to
use that configuration, leading to broken display.

Fix the problem by allowing DIGIT channel to go only to HDMI output.

OMAPDSS: constify port arrays

2015-02-04T10:32:03+00:00

The port arrays are constant data, so set them as 'const'.
