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.

We're not super-consistent about these, but I think it's worth to document at least the commmon patterns. v2: - Add a not about ENOTTY (it's just a confusing name, but used exactly what it's meant for in DRM) (Chris). - Unconfuse the text for ENODEV (Daniel) - Move text undert the IOCTL heading (Chris). - typos Cc: Daniel Stone <daniel@fooishbar.org> Cc: Joonas Lahtinen <joonas.lahtinen@linux.intel.com> Cc: Chris Wilson <chris@chris-wilson.co.uk> Cc: "Zhang, Tina" <tina.zhang@intel.com> Reviewed-by:

Add defines for the secondary data packet (SDP) types from the spec. These are the DP specific ones, and in addition HDMI infoframe types (see enum hdmi_infoframe_type) are also valid SDP types. v2: Add more SDP types v3: Note the DP version that added each SDP type (Rodrigo) Cc: dri-devel@lists.freedesktop.org Reviewed-by:

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. For this reason the simple panel driver cannot be used to drive this panel, so create a new one heavily based on simple panel. Based on initial patch submission from Breno Lima. Signed-off-by:
