drm/msm: restart queued submits after hang

2015-06-11T17:11:06+00:00

Track the list of in-flight submits. If the gpu hangs, retire up to an including the offending submit, and then re-submit the remainder. This way, for concurrently running piglit tests (for example), one failing test doesn't cause unrelated tests to fail simply because it's submit was queued up after one that triggered a hang.

drm/msm: fix timeout calculation

2015-06-11T17:11:06+00:00

The 'timeout' value comes from userspace (CLOCK_MONOTONIC), but converting this directly to jiffies doesn't take into account the initial jiffies count at boot, which may differ from the base time of CLOCK_MONOTONIC. TODO: add ktime_delta_jiffies() when rebasing on 4.1 and use that instead of ktime_sub/ktime_to_timespec/timespec_to_jiffies combo (as suggested by Arnd) v2: switch over from 'struct timespec' to ktime_t throughout, since 'struct timespec' will be deprecated (as suggested by Arnd) v3: minor cosmetic tweaks Cc: Arnd Bergmann Signed-off-by: Rob Clark

drm/msm/hdmi: Use pinctrl in HDMI driver

2015-06-11T17:11:06+00:00

Some targets (eg: msm8994) use the pinctrl framework to configure interface pins. This change adds support for initialization and pinctrl active/sleep state control for the HDMI driver. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/hdmi: Point to the right struct device

2015-06-11T17:11:06+00:00

DRM device's dev (hdmi->dev->dev) points to the mdss_mdp device handle. Instead, we should get a reference to the mdss_hdmi handle. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/mdp: Add support for more 32-bit RGB formats

2015-06-11T17:11:05+00:00

That will complete the lists of Alpha + RGB formats. Signed-off-by: Stephane Viau Signed-off-by: Rob Clark

drm/msm/atomic: Clean up planes in the error paths of .atomic_commit()

2015-06-11T17:11:05+00:00

When the .atomic_commit() handler fails, clean up planes previoulsy prepared by drm_atomic_helper_prepare_planes() with a call to drm_atomic_helper_cleanup_planes(). Signed-off-by: Laurent Pinchart Signed-off-by: Rob Clark

drm/msm/mdp5: Always generate active-high sync signals for DSI

2015-06-11T17:11:05+00:00

DSI video mode engine can only take active-high sync signals. This change prevents MDP5 sending active-low sync signals to DSI in any case. Signed-off-by: Hai Li Tested-by: Archit Taneja Signed-off-by: Rob Clark

drm/msm: dsi: fix compile errors when CONFIG_GPIOLIB=n

drm/msm: use devm_gpiod_get_optional for optional reset gpio

2015-06-11T17:11:05+00:00

Since 39b2bbe3d715 (gpio: add flags argument to gpiod_get*() functions) which appeared in v3.17-rc1, the gpiod_get* functions take an additional parameter that allows to specify direction and initial value for output. Also there is a variant to find optional gpios that returns NULL if there is no gpio instead of -ENOENT. Make use of both features to simplify the driver. This makes error checking more strict because errors like -ENOSYS ("no gpio support compiled in") or -EPROBE_DEFER ("gpio not ready yet") are handled correctly now. Furthermore this is one caller less that stops us making the flags argument to gpiod_get*() mandatory. Reviewed-by: Linus Walleij Signed-off-by: Uwe Kleine-König Signed-off-by: Rob Clark

drm/msm/dsi: Separate PHY to another platform device

2015-06-11T17:11:05+00:00

There are different types of PHY from one chipset to another, while the DSI host controller is relatively consistent across platforms. Also, the PLL inside PHY is providing the source of DSI byte and pixel clocks, which are used by DSI host controller. Separated devices for clock provider and clock consumer make DSI driver better fit into common clock framework. Signed-off-by: Hai Li Signed-off-by: Rob Clark
