2013-03-25[media] v4l2: add new VIDIOC_DBG_G_CHIP_NAME ioctlHans Verkuil
Simplify the debugging ioctls by creating the VIDIOC_DBG_G_CHIP_NAME ioctl. This will eventually replace VIDIOC_DBG_G_CHIP_IDENT. Chip matching is done by the name or index of subdevices or an index to a bridge chip. Most of this can all be done automatically, so most drivers just need to provide get/set register ops. In particular, it is now possible to get/set subdev registers without requiring assistance of the bridge driver.

2013-03-24[media] sony-btf-mpx: the MPX driver for the sony BTF PAL/SECAM tunerHans Verkuil
The Sony BTF PG472Z has an internal MPX to deal with mono/stereo/bilingual audio. This is split off from the wis-sony-tuner driver that is part of the go7007 driver as it should be a separate i2c sub-device driver. The wis-sony-tuner is really three i2c devices: a standard tuner, a tda9887 compatible demodulator and this mpx. After this patch the wis-sony-tuner can be replaced by this driver and the standard tuner driver.

2013-03-24[media] v4l2-ioctl: check if an ioctl is validHans Verkuil
Just checking if the op exists isn't correct, you should check if the ioctl is valid (which implies that the op exists as well). One exception is g_std: if current_norm is non-zero, then the g_std op may be absent. This sort of weird behavior is one of the reasons why I am trying to get rid of current_norm. This patch fixes the case where the g/s_std op is set, but these ioctls are disabled. This can happen in drivers supporting multiple models, some that have TV input (and support the STD API) and some that have a sensor (and do not support the STD API). In the latter case qv4l2 would still show the Standards combobox. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] v4l2-ctrls: eliminate lockdep false alarms for struct ↵Andy Walls
v4l2_ctrl_handler.lock When calling v4l2_ctrl_add_handler(), lockdep would detect a potential recursive locking problem on a situation that is by design intended and not a recursive lock. This happened because all struct v4l2_ctrl_handler.lock mutexes were created as members of the same lock class in v4l2_ctrl_handler_init(), and v4l2_ctrl_add_handler() takes the hdl->lock on two different v4l2_ctrl_handler instances. This change breaks the large lockdep lock class for struct v4l2_ctrl_handler.lock and breaks it into v4l2_ctrl_handler instantiation specific lock classes with meaningful class names. This will validly eliminate lockdep alarms for v4l2_ctrl_handler locking validation, as long as the relationships between drivers adding v4l2 controls to their own handler from other v4l2 drivers' control handlers remains straightforward. struct v4l2_ctrl_handler.lock lock classes are created with names such that the output of cat /proc/lockdep indicates where in the v4l2 driver code v4l2_ctrl_handle_init() is being called on instantiations: ffffffffa045f490 FD: 10 BD: 8 +.+...: cx2341x:1534:(hdl)->lock ffffffffa0497d20 FD: 12 BD: 2 +.+.+.: saa7115:1581:(hdl)->lock ffffffffa04ac660 FD: 14 BD: 2 +.+.+.: msp3400_driver:756:(hdl)->lock ffffffffa0484b90 FD: 12 BD: 1 +.+.+.: ivtv_gpio:366:(&itv->hdl_gpio)->lock ffffffffa04eb530 FD: 11 BD: 2 +.+.+.: cx25840_core:1982:(&state->hdl)->lock ffffffffa04fbc80 FD: 11 BD: 3 +.+.+.: wm8775:246:(&state->hdl)->lock Some lock chains, that were previously causing the recursion alarms, are now visible in the output of cat /proc/lockdep_chains: irq_context: 0 [ffffffffa0497d20] saa7115:1581:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04ac660] msp3400_driver:756:(hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa0484b90] ivtv_gpio:366:(&itv->hdl_gpio)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04eb530] cx25840_core:1982:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock irq_context: 0 [ffffffffa04fbc80] wm8775:246:(&state->hdl)->lock [ffffffffa045f490] cx2341x:1534:(hdl)->lock Signed-off-by: Andy Walls <awalls@md.metrocast.net> [hans.verkuil@cisco.com: keep mutex_init in v4l2_ctrl_handler_init_class] Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2013-03-24[media] v4l2-ioctl: simplify debug codeHans Verkuil
The core debug code can now be simplified since all the write-only ioctls are now const and will not modify the data they pass to the drivers.
