media: staging: davinci: remove vpfe driver 

The davinci_vpfe driver was merged into staging back in 2012 by Manjunath
Hadli from TI, with a long TODO list.

For all I can tell, since then it has only seen fixes for compile-time
issues and global cleanups, but nobody has actually worked on the items
on the TODO list.

To make things worse, the driver in its current form is incompatible with
the platform code in arch/arm/mach-davinci, i.e. the driver expects to
get its platform_data passed to the device as a 'struct vpfe_config',
but uses a differnet definition for that structure compared to what the
platform uses.

Finally, there is another driver for the same device in
drivers/media/platform/davinci/vpfe_capture.c. From all I can tell, the
staging version was originally a copy of a more featureful driver in TI's
downstream kernels. However, that kernel no longer supports dm365 after
linux-2.6.37, and the mainline version moved in a different direction.

TODO (general):
==================================
- User space interface refinement
- Controls should be used when possible rather than private ioctl
- No enums should be used
- Use of MC and V4L2 subdev APIs when applicable
- Single interface header might suffice
- Current interface forces to configure everything at once
- Get rid of the dm365_ipipe_hw.[ch] layer
- Active external sub-devices defined by link configuration; no strcmp
needed
- More generic platform data (i2c adapters)
- The driver should have no knowledge of possible external subdevs; see
struct vpfe_subdev_id
- Some of the hardware control should be refactorede
- Check proper serialisation (through mutexes and spinlocks)
- Names that are visible in kernel global namespace should have a common
prefix (or a few)
- While replacing the older driver in media folder, provide a compatibility
layer and compatibility tests that warrants (using the libv4l's LD_PRELOAD
approach) there is no regression for the users using the older driver.
- make it independent of arch-specific APIs (mach/mux.h).
Building of uImage and Applications:
==================================
As of now since the interface will undergo few changes all the include
files are present in staging itself, to build for dm365 follow below steps,
- copy vpfe.h from drivers/staging/media/davinci_vpfe/ to
include/media/davinci/ folder for building the uImage.
- copy davinci_vpfe_user.h from drivers/staging/media/davinci_vpfe/ to
include/uapi/linux/davinci_vpfe.h, and add a entry in Kbuild (required
for building application).
- copy dm365_ipipeif_user.h from drivers/staging/media/davinci_vpfe/ to
include/uapi/linux/dm365_ipipeif.h and a entry in Kbuild (required
for building application).

Davinci Video processing Front End (VPFE) driver
Copyright (C) 2012 Texas Instruments Inc
Contacts: Manjunath Hadli <manjunath.hadli@ti.com>
Prabhakar Lad <prabhakar.lad@ti.com>
Introduction
============
This file documents the Texas Instruments Davinci Video processing Front End
(VPFE) driver located under drivers/media/platform/davinci. The original driver
exists for Davinci VPFE, which is now being changed to Media Controller
Framework.
Currently the driver has been successfully used on the following
version of Davinci:
DM365/DM368
The driver implements V4L2, Media controller and v4l2_subdev interfaces. Sensor,
lens and flash drivers using the v4l2_subdev interface in the kernel are
supported.
Split to subdevs
================
The Davinci VPFE is split into V4L2 subdevs, each of the blocks inside the VPFE
having one subdev to represent it. Each of the subdevs provide a V4L2 subdev
interface to userspace.
DAVINCI ISIF
DAVINCI IPIPEIF
DAVINCI IPIPE
DAVINCI CROP RESIZER
DAVINCI RESIZER A
DAVINCI RESIZER B
Each possible link in the VPFE is modelled by a link in the Media controller
interface. For an example program see [1].
ISIF, IPIPE, and RESIZER block IOCTLs
======================================
The Davinci Video processing Front End (VPFE) driver supports standard V4L2
IOCTLs and controls where possible and practical. Much of the functions provided
by the VPFE, however, does not fall under the standard IOCTL's.
In general, there is a private ioctl for configuring each of the blocks
containing hardware-dependent functions.
The following private IOCTLs are supported:
VIDIOC_VPFE_ISIF_[S/G]_RAW_PARAMS
VIDIOC_VPFE_IPIPE_[S/G]_CONFIG
VIDIOC_VPFE_RSZ_[S/G]_CONFIG
The parameter structures used by these ioctl's are described in
include/uapi/linux/davinci_vpfe.h.
The VIDIOC_VPFE_ISIF_S_RAW_PARAMS, VIDIOC_VPFE_IPIPE_S_CONFIG and
VIDIOC_VPFE_RSZ_S_CONFIG are used to configure, enable and disable functions in
the isif, ipipe and resizer blocks respectively. These IOCTL's control several
functions in the blocks they control. VIDIOC_VPFE_ISIF_S_RAW_PARAMS IOCTL
accepts a pointer to struct vpfe_isif_raw_config as its argument. Similarly
VIDIOC_VPFE_IPIPE_S_CONFIG accepts a pointer to struct vpfe_ipipe_config. And
VIDIOC_VPFE_RSZ_S_CONFIG accepts a pointer to struct vpfe_rsz_config as its
argument. Similarly VIDIOC_VPFE_ISIF_G_RAW_PARAMS, VIDIOC_VPFE_IPIPE_G_CONFIG
and VIDIOC_VPFE_RSZ_G_CONFIG are used to get the current configuration set in
the isif, ipipe and resizer blocks respectively.
The detailed functions of the VPFE itself related to a given VPFE block is
described in the Technical Reference Manuals (TRMs) --- see the end of the
document for those.
IPIPEIF block IOCTLs
======================================
The following private IOCTLs are supported:
VIDIOC_VPFE_IPIPEIF_[S/G]_CONFIG
The parameter structures used by these ioctl's are described in
include/uapi/linux/dm365_ipipeif.h
The VIDIOC_VPFE_IPIPEIF_S_CONFIG is used to configure the ipipeif
hardware block. The VIDIOC_VPFE_IPIPEIF_S_CONFIG and
VIDIOC_VPFE_IPIPEIF_G_CONFIG accepts a pointer to struct ipipeif_params
as its argument.

* Driver name : VPFE Capture driver
* VPFE Capture driver allows applications to capture and stream video
* frames on DaVinci SoCs (DM6446, DM355 etc) from a YUV source such as
* TVP5146 or Raw Bayer RGB image data from an image sensor
* such as Microns' MT9T001, MT9T031 etc.
*
* These SoCs have, in common, a Video Processing Subsystem (VPSS) that
* consists of a Video Processing Front End (VPFE) for capturing
* video/raw image data and Video Processing Back End (VPBE) for displaying
* YUV data through an in-built analog encoder or Digital LCD port. This
* driver is for capture through VPFE. A typical EVM using these SoCs have
* following high level configuration.
*
* decoder(TVP5146/ YUV/
* MT9T001) --> Raw Bayer RGB ---> MUX -> VPFE (CCDC/ISIF)
* data input | |
* V |
* SDRAM |
* V
* Image Processor
* |
* V
* SDRAM
* The data flow happens from a decoder connected to the VPFE over a
* YUV embedded (BT.656/BT.1120) or separate sync or raw bayer rgb interface
* and to the input of VPFE through an optional MUX (if more inputs are
* to be interfaced on the EVM). The input data is first passed through
* CCDC (CCD Controller, a.k.a Image Sensor Interface, ISIF). The CCDC
* does very little or no processing on YUV data and does pre-process Raw
* Bayer RGB data through modules such as Defect Pixel Correction (DFC)
* Color Space Conversion (CSC), data gain/offset etc. After this, data
* can be written to SDRAM or can be connected to the image processing
* block such as IPIPE (on DM355/DM365 only).
*
* Features supported
* - MMAP IO
* - USERPTR IO
* - Capture using TVP5146 over BT.656
* - Support for interfacing decoders using sub device model
* - Work with DM365 or DM355 or DM6446 CCDC to do Raw Bayer
* RGB/YUV data capture to SDRAM.
* - Chaining of Image Processor
* - SINGLE-SHOT mode
