The header comment in include/trace/define_trace.h specifies that the TRACE_INCLUDE_PATH needs to be relative to the define_trace.h header rather than the trace file including it. Most instances get that wrong and work around it by adding the $(src) directory to the include path. While this works, it is preferable to refer to the correct path to the trace file in the first place and avoid any workaround. Acked-by:

Based on patch "Convert drivers to explicit reset API" from Philipp Zabel Commit a53e35db ("reset: Ensure drivers are explicit when requesting reset lines") started to transition the reset control request API calls to explicitly state whether the driver needs exclusive or shared reset control behavior. Convert all drivers requesting exclusive resets to the explicit API call so the temporary transition helpers can be removed. No functional changes.

This replaces the custom connector in the TVE200 with the panel bridge helper. As long as we're just using panels and no other bridges, this works just fine. Reviewed-by:

drm_fb_helper_resume_worker() uses fb_helper->fbdev to call fb_set_suspend() which dereferences the pointer. Move sync-canceling of the resume worker in drm_fb_helper_fini() before setting fb_helper->fbdev to NULL. Move dirty_work as well. Signed-off-by:

Linus Walleij authored
This adds a new DRM driver for the Faraday Technology TVE200 block. This "TV Encoder" encodes a ITU-T BT.656 stream and can be found in the StorLink SL3516 (later Cortina Systems CS3516) as well as the Grain Media GM8180. I do not have definitive word from anyone at Faraday that this IP block is theirs, but it bears the hallmark of their 3-digit version code (200) and is used in two SoCs from completely different companies. (Grain Media was fully owned by Faraday until it was transferred to NovoTek this january, and Faraday did lots of work on the StorLink SoCs.) The D-Link DIR-685 uses this in connection with the Ilitek ILI9322 panel driver that supports BT.656 input, while the GM8180 apparently has been used with the Cirrus Logic CS4954 digital video encoder. The oldest user seems to be something called Techwall 2835. This driver is heavily inspired by Eric Anholt's PL111 driver and therefore I have mentioned all the ancestor authors in the header file.

This is the same bug as we fixed in commit f6cd7dae ("drm: Release driver references to handle before making it available again"), but now the exposure is via the PRIME lookup tables. If we remove the object/handle from the PRIME lut, then a new request for the same object/fd will generate a new handle, thus for a short window that object is known to userspace by two different handles. Fix this by releasing the driver tracking before PRIME. Fixes: 0ff926c7 ("drm/prime: add exported buffers to current fprivs imported buffer list (v2)") Signed-off-by:

Add driver for Seiko Instruments Inc. 4.3" WVGA (800 x RGB x 480) TFT with Touch-Panel. Datasheet available at: http://www.glyn.de/data/glyn/media/doc/43wvf1g-0.pdf Seiko 43WVF1G panel has two power supplies: avdd and dvdd and they require a specific power on/down sequence.
