fbcon: unconditionally initialize cursor blink interval

2015-08-10T14:20:32Z

A sun7i-a20-olinuxino-micro fails to boot when kernel parameter vt.global_cursor_default=0. The value is copied to vc->vc_deccm causing the initialization of ops->cur_blink_jiffies to be skipped. Unconditionally initialize it. Reported-and-tested-by: Jonathan Liu Signed-off-by: Scot Doyle Acked-by: Pavel Machek Signed-off-by: Tomi Valkeinen

video: Fix possible leak in of_get_videomode()

2015-08-10T12:11:12Z

In case videomode_from_timings() fails in function of_get_videomode(), the allocated display timing data is not freed in the exit path. Make sure that display_timings_release() is called in any case.

OMAPDSS: Fix omap_dss_find_output_by_port_node() port refcount decrement

2015-08-10T09:22:40Z

Fix omap_dss_find_output_by_port_node() port parameter refcount decrementation. The only user of dss_of_port_get_parent_device() function is omap_dss_find_output_by_port_node() and it assumes the refcount of the port parameter is not decremented by the call.

fbdev: select versatile helpers for the integrator

2015-08-10T09:20:38Z

Commit 11c32d7b6274cb0f554943d65bd4a126c4a86dcd "video: move Versatile CLCD helpers" missed the fact that the Integrator/CP is also using the helper, and as a result the platform got only stubs and no graphics. Add this as a default selection to Kconfig so we have graphics again. Fixes: 11c32d7b6274 (video: move Versatile CLCD helpers) Signed-off-by: Linus Walleij Signed-off-by: Tomi Valkeinen

stifb: Implement hardware accelerated copyarea

2015-07-10T19:44:19Z

This patch adds hardware assisted scrolling. The code is based upon the following investigation: https://parisc.wiki.kernel.org/index.php/NGLE#Blitter A simple 'time ls -la /usr/bin' test shows 1.6x speed increase over soft copy and 2.3x increase over FBINFO_READS_FAST (prefer soft copy over screen redraw) on Artist framebuffer.

OMAPDSS: fix probing if rfbi device is enabled

2015-07-02T12:20:10Z

After the commit 736e60ddc215b85e73bbf7da26e1cde84cc9500f ("OMAPDSS: componentize omapdss") the dss core device will wait until all the subdevices have been successfully probed. However, we don't have a working driver for RFBI, so if RFBI device exists, omapdss will never get probed. All the .dtsi files set RFBI as disabled, except am4372.dtsi. This causes omapdss probe to not finish on AM4 devices. This patch makes omapdss driver skip adding rfbi device as a subcomponent, solving the issue. This should be reverted when we have a working RFBI driver. Signed-off-by: Tomi Valkeinen Reported-by: Felipe Balbi

Pull module updates from Rusty Russell: "Main excitement here is Peter Zijlstra's lockless rbtree optimization to speed module address lookup. He found some abusers of the module lock doing that too. A little bit of parameter work here too; including Dan Streetman's breaking up the big param mutex so writing a parameter can load another module (yeah, really).
