OMAPDSS: fix regression with display sysfs files

2015-02-26T08:23:15Z

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.

video: fbdev: fix possible null dereference

2015-02-26T08:23:15Z

we were dereferencing edid first and the NULL check was after accessing that. now we are using edid only if we know that it is not NULL. Signed-off-by: Sudip Mukherjee Signed-off-by: Tomi Valkeinen

video: ARM CLCD: Add missing error check for devm_kzalloc

2015-02-26T08:23:15Z

This patch add a missing check on the return value of devm_kzalloc, which would cause a NULL pointer dereference in a OOM situation. Signed-off-by: Kiran Padwal Signed-off-by: Tomi Valkeinen

OMAPDSS: DPI: DRA7xx support

2015-02-04T10:32:07Z

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. Signed-off-by: Tomi Valkeinen

OMAPDSS: HDMI: Add DRA7xx support

2015-02-04T10:32:06Z

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. Signed-off-by: Tomi Valkeinen
