Currently, the hardware is not given a complete initial configuration. In order to fix this, this rather large commit reworks standard, frame format and input configuration. While at it, we introduce proper functions to configure each parameter, and as a result the code is a bit cleaner. Reported-by:

The V4L2_YCBCR_ENC_SYCC encoding is identical to V4L2_YCBCR_ENC_601. Remove V4L2_YCBCR_ENC_SYCC from the documentation since it should not be used. Signed-off-by:

This define is a duplicate of V4L2_YCBCR_ENC_601. So mark it as 'should not be used' and put it under #ifndef __KERNEL__ to prevent drivers from referring to it. Signed-off-by:

The SYCC Y'CbCr encoding is identical to the 601 encoding. Since the SYCC define is about to be removed for use in the kernel we need to drop it in the TPG code as well. This patch also adds a 4th decimal to the 601 conversion matrix. That was specified by the sYCC spec and it makes sense to use this across the board.

This encoding is identical to the 601 encoding. The old duplicate SYCC define is about to be removed for use in the kernel, so remove its use in vivid first. Signed-off-by:

The default quantization range of the Y'CbCr encodings of sRGB and AdobeRGB are full range instead of limited range according to the corresponding standards. Fix this in the V4L2_MAP_QUANTIZATION_DEFAULT macro. Signed-off-by:

The functionality that was part of the tw686x-kh driver but not of the mainlined tw686x driver has now been added to the tw686x driver as well. So this driver no longer adds any functionality not available through the mainlined driver and it can now be removed. Signed-off-by:

The touchscreen may have a margin where not all the matrix is used. Read the parameters from T9 and T100 and take account of the difference. Note: this does not read the XORIGIN/YORIGIN fields so it assumes that the touchscreen starts at (0,0) Signed-off-by:

Some touch controllers send out touch data in a similar way to a greyscale frame grabber. Add new device type VFL_TYPE_TOUCH: - This uses a new device prefix v4l-touch for these devices, to stop generic capture software from treating them as webcams. Otherwise, touch is treated similarly to video capture. - Add V4L2_INPUT_TYPE_TOUCH - Add MEDIA_INTF_T_V4L_TOUCH - Add V4L2_CAP_TOUCH to indicate device is a touch device Add formats: - V4L2_TCH_FMT_DELTA_TD16 for signed 16-bit touch deltas - V4L2_TCH_FMT_DELTA_TD08 for signed 16-bit touch deltas - V4L2_TCH_FMT_TU16 for unsigned 16-bit touch data - V4L2_TCH_FMT_TU08 for unsigned 8-bit touch data This support will be used by: - Atmel maXTouch (atmel_mxt_ts) - Synaptics RMI4. - sur40 Signed-off-by:

The primary reason for this change is to prepare for Gen3 support where there will be more then one possible video source. Each source will have its own media bus format and code, so it needs to be moved from the per device structure to a structure used to represent an individual connection to a video source.

The original drivers code to find a subdevice by looking in the DT grpah and how the callbacks to the v4l2 async bind framework where poorly written. The most obvious example of badness was the duplication of data in the struct rvin_graph_entity. This patch removes the data duplication, simplifies the parsing of the DT graph and add checks to the v4l2 callbacks. Signed-off-by:

Fix a error from the original driver where v4l2_device_call_until_err() where used for the pad specific v4l2 operation set_fmt. Also fix up the error path from this fix so if there is an error it will be propagated to the caller. The error path label have also been renamed as a result from a nitpicking review comment since we are fixing other issues here. Signed-off-by:

The Sphinx 1.4.x definition for \DUrole is: \providecommand*{\DUrole}[2]{% \ifcsname DUrole#1\endcsname% \csname DUrole#1\endcsname{#2}% \else% backwards compatibility: try \docutilsrole#1{#2} \ifcsname docutilsrole#1\endcsname% \csname docutilsrole#1\endcsname{#2}% \else% #2% \fi% \fi% } This is broken when it is used inside a \begin{alltt} block. So, replace it by just "#2", as this won't cause troubles, and it is one of the fallback methods for it. Signed-off-by: -
