drm/exynos/dsi: make te-gpios optional

2017-03-21T05:30:18Z

DSI forwards te-gpios interrupts to display controller, but if display controller works in HW-TRIGGER mode this interrupt is not necessary. Making te-gpios property optional allows to avoid generating spare interrupts. And also if panel device node of command mode panel device doesn't provide te-gpios property then the panel driver failed to probe. This was a critial issue. With this patch we can not only get rid of 60 interrupt callbacks per second but also fix the critial issues. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos: Print kernel pointers in a restricted form

2017-03-21T04:17:22Z

Printing raw kernel pointers might reveal information which sometimes we try to hide (e.g. with Kernel Address Space Layout Randomization). Use the "%pK" format so these pointers will be hidden for unprivileged users. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Inki Dae

drm/exynos/fimd: signal frame done interrupt at front porch

2017-03-21T04:17:22Z

VBLANK interrupt should be signalled as soon as scanout ends, front porch is the best moment. Signed-off-by: Andrzej Hajda Signed-off-by: Inki Dae

drm/exynos/decon5433: signal frame done interrupt at front porch

2017-03-21T04:17:22Z

DECON in case of video mode generates interrupt by default at start of vertical back porch. As this interrupt is used to generate VBLANK events more optimal point is start of vertical front porch. Signed-off-by: Inki Dae

drm/exynos/decon5433: fix vblank event handling

2017-03-21T04:17:21Z

Current implementation of event handling assumes that vblank interrupt is always called at the right time. It is not true, it can be delayed due to various reasons. As a result different races can happen. The patch fixes the issue by using hardware frame counter present in DECON to serialize vblank and commit completion events.

drm/exynos: move crtc event handling to drivers callbacks

2017-03-21T04:17:21Z

CRTC event is currently send with next vblank, or instantly in case crtc is being disabled. This approach usually works, but in corner cases it can result in premature event generation. Only device driver is able to verify if the event can be sent. This patch is a first step in that direction - it moves event handling to the drivers.

drm/exynos: Remove support for Exynos4415 (SoC not supported anymore)

2017-03-21T04:17:21Z

Support for Exynos4415 is going away because there are no internal nor external users. Since commit 46dcf0ff0de3 ("ARM: dts: exynos: Remove exynos4415.dtsi"), the platform cannot be instantiated so remove also the drivers.

"&" was obviously intended instead of "|". The original condition is always true. Fixes: b93c2e8b5d9d ("drm/exynos/decon5433: configure sysreg in case of hardware trigger") Signed-off-by: Dan Carpenter Signed-off-by: Inki Dae

mm, fs: reduce fault, page_mkwrite, and pfn_mkwrite to take only vmf

2017-02-25T01:46:54Z

->fault(), ->page_mkwrite(), and ->pfn_mkwrite() calls do not need to take a vma and vmf parameter when the vma already resides in vmf. Remove the vma parameter to simplify things.
