2009-03-30V4L/DVB (11305): cx88: prevent probing rtc and ir devicesHans Verkuil1-4/+10
tuner-core.c contains a hack for cx88 board to prevent probing of certain addresses: /* HACK: Ignore 0x6b and 0x6f on cx88 boards. * FusionHDTV5 RT Gold has an ir receiver at 0x6b * and an RTC at 0x6f which can get corrupted if probed. */ With the new i2c API this hack no longer works.

Convert cx88 to use v4l2_subdev since the old i2c autoprobing mechanism will be removed. Added code to explicitly load tvaudio where needed.

Convert this driver to v4l2_subdev. Note that currently the only card with analog support in this driver is the HVR-1800. The analog tuner support in this driver is limited to what is needed for this board. When analog support is added for other cards, then the tuner load code will probably have to be expanded to take care of those boards. For example, there is currently no support for either radio tuners or tda9887 demods. I'd like to thank Steven Toth for testing this on his HVR-1800.

2009-03-30V4L/DVB (11278): bttv: convert to v4l2_subdev since i2c autoprobing will disappear.Hans Verkuil5-105/+180
Since i2c autoprobing will disappear bttv needs to be converted to use v4l2_subdev instead. Without autoprobing the autoload module option has become obsolete. A warning is generated if it is set, but it is otherwise ignored. Since the bttv card definitions are of questionable value a new option was introduced to allow the user to control which audio module is selected: msp3400, tda7432 or tvaudio (or none at all). By default bttv will use the card definitions and fallback on tvaudio as the last resort. If no audio device was found a warning is printed. The saa6588 RDS device is now also explicitly probed since it is no longer possible to autoprobe it. A new saa6588 module option was added to override the card definition since I suspect more cards have this device than one would guess from the card definitions. Note that the probe addresses of the i2c modules are hardcoded in this driver. Once all v4l drivers are converted to v4l2_subdev this will be cleaned up. Such data belongs in an i2c driver header.

In the tvaudio_remove function del_timer_sync(&chip->wt) is called. However, chip->wt isn't always initialized depending on the type of audio chip.

2009-03-30V4L/DVB (11276): tvaudio: add tda9875 support.Hans Verkuil1-0/+132
This change allows bttv to use tvaudio for this device. Since this device has the same i2c address as the tda9874 we need to support both in the same tvaudio driver. This makes it possible for tvaudio to detect which chip is used. Originally the tda9875 was only available in the dedicated tda9875 driver, but that makes life very hard for bttv since loading tvaudio might misdetect a tda9875 as a tda9874.

2009-03-30V4L/DVB (11275): tvaudio: fix mute and s/g_tuner handlingHans Verkuil1-5/+19
The mute control depends on CHIP_HAS_INPUTSEL, so test for that first. The s/g_tuner code should check whether getmode/setmode is set at the beginning instead of filling in the struct and discovering at the end that this chip doesn't implement audiomodes after all (i.e. is a simple muxer chip).

The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the buffer's 'type' field since it must already be set to VIDEO_CAPTURE.

The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code can be removed from zr364xx_vidioc_querycap(), zr364xx_vidioc_enum_input(), zr364xx_vidioc_enum_fmt_vid_cap(), and zr364xx_vidioc_g_fmt_vid_cap().

The v4l2 core code in v4l2_ioctl will zero out the structure the driver is supposed to fill in for read-only ioctls. For read/write ioctls, all the fields which aren't supplied from userspace will be zeroed out. Zeroing code is removed from enum_input, g_tuner, g_frequency, querycap, enum_fmt_vid_cap, g_fmt_vid_cap, and try_fmt_vid_cap. The ->vidioc_(s|g|try|enum)_fmt_vid_cap() methods are only called on VIDEO_CAPTURE buffers. Thus, there is no need to check or set the buffer's 'type' field since it must already be set to VIDEO_CAPTURE. There also appeared to be a copy and paste error in vidioc_try_fmt_vid_cap() that would set f->fmt.pix.sizeimage to zero. Note that the s_fmt_vid_cap method doesn't appear to actually do anything. Whatever parameters were requested are just silently ignored. Was this intentional? Who knows, as the commit log entry for the driver just says, "Add generic cx23417 hardware encoder support." There are no docs. A comment like "this driver totally ignores the v4l2 spec w.r.t. VIDIOC_S_FMT because ..." would have gone a long way.

The v4l2-ioctl core only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(q|dq|query)bufs(), vidioc_reqbufs() and now vidioc_(s|g)_parm. The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() and ->vidioc_try_fmt_vbi_cap() it will now allow VIDEO_OVERLAY and VBI_CAPTURE buffers as well. This should be fine as the driver only fills in the frame rate field, which is just as valid for video overlay and vbi capture as it is for video capture.

2009-03-30V4L/DVB (11261): saa7146: Remove buffer type check from vidioc_g_parmTrent Piepho1-2/+0
The v4l2-ioctl core now only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used with vidioc_(g|s)_parm. The driver was only allowing VIDEO_CAPTURE buffers for g_parm, but since the driver defines ->vidioc_try_fmt_vid_overlay() it will now allow VIDEO_OVERLAY buffers as well. This should be fine as the fields the driver fills in, readbuffers and frame rate, aren't wrong for VIDEO_OVERLAY buffers.

2009-03-30V4L/DVB (11260): v4l2-ioctl: Check format for S_PARM and G_PARMTrent Piepho1-0/+7
Return EINVAL if VIDIOC_S/G_PARM is called for a buffer type that the driver doesn't define a ->vidioc_try_fmt_XXX() method for. Several other ioctls, like QUERYBUF, QBUF, and DQBUF, etc. do this too. It saves each driver from having to check if the buffer type is one that it supports.
