Function 54 implements access to various RMI4 diagnostic features. This patch adds support for retrieving this data. It registers a V4L2 device to output the data to user space. 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:

Register a video device to output T37 diagnostic data. Signed-off-by:

Nick Dyer authored
Atmel maXTouch devices have a T37 object which can be used to read raw touch deltas from the device. This consists of an array of 16-bit integers, one for each node on the touchscreen matrix. 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:

I'm leaving ITDev, so change to my personal email. My understanding is that someone at Atmel will take this on once their takeover by Microchip has settled down. 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:

The check for if the specific pixelformat is supported on the current chip should happen in VIDIOC_S_FMT and VIDIOC_TRY_FMT and not when we try to setup the hardware for streaming. Signed-off-by:

This is done in preparation for Gen3 support where media controller support will be mandatory for the driver. 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:

When Gen3 support is added to the driver more then one possible video source entity will be possible. Knowing that the name entity is a bad one, rename it to digital since it will deal with the digital input source. 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: -

Name all ioctl references and make them match the ioctls that are documented. That will improve the cross-reference index, as it will have all ioctls and syscalls there. While here, improve the documentation to make them to look more like the rest of the document. Signed-off-by: -

While here, improve the documentation, marking the deprecated ioctls, and making the non-deprecated ones more like the rest of the media book. Also, add a notice for ioctls that still require documentation. Signed-off-by: -

Instead of painting the box with gray, let's use a colored box. IMHO, that makes easier to warn users about some issue pointed by the Sphinx. It also matches to what we do already with the HTML output. Signed-off-by:

While the current implementation works well when using as a paragraph, it doesn't work properly if inside a table. As we have quite a few such cases, fix the logic to take the column size into account. PS.: I took the logic there from the latest version of Sphinx.sty Signed-off-by:

This is only one example, demonstrating the benefits of the patch series. The CEC_DQEVENT ioctl is migrated to the sphinx c-domain and referred by ":name: CEC_DQEVENT". With this change the indirection using ":ref:`CEC_DQEVENT` is no longer needed, we can refer the ioctl directly with ":c:func:`CEC_DQEVENT`". As addition in the index, there is a entry "CEC_DQEVENT (C function)". Signed-off-by:

This reverts commit a88b1672. From the origin comit log:: The RST cpp:function handler is very pedantic: it doesn't allow any macros like __user on it Since the kernel-doc parser does NOT make use of the cpp:domain, there is no need to change the kernel-doc parser eleminating the address_space tags.

Moved the *duplicate C object description* warnings for function declarations in the nitpicky mode. In nitpick mode, you can suppress those warnings (e.g. ioctl) with:: nitpicky = True nitpick_ignore = [ ("c:func", "ioctl"), ] See Sphinx documentation for the config values for ``nitpick`` and ``nitpick_ignore`` [1]. With this change all the ".. cpp:function:: int ioctl(..)" descriptions (found in the media book) can be migrated to ".. c:function:: int ioctl(..)", without getting any warnings. E.g.:: .. cpp:function:: int ioctl( int fd, int request, struct cec_event *argp ) .. c:function:: int ioctl( int fd, int request, struct cec_event *argp ) The main effect, is that we get those *CPP-types* back into Sphinx's C- namespace and we need no longer to distinguish between c/cpp references, when we refer a function like the ioctl.
