* V4L/DVB: cx2341x: convert to the control frameworkHans Verkuil2010-08-08
| | | | | | | | | | | | | | | | Since this module is also used by drivers that are not yet converted, the old and new code have to co-exist. The source is split into three parts: a common part at the top, which is used by both old and new code, then the old code followed by the new control framework implementation. This new code is much more readable (and shorter!) than the original code. Once all bridge drivers that use this are converted the old code can be deleted.

* V4L/DVB: cx25840/ivtv: replace ugly priv control with s_configHans Verkuil2010-08-08
| | | | | | | | | | | | The cx25840 used a private control CX25840_CID_ENABLE_PVR150_WORKAROUND to be told whether to enable a workaround for certain pvr150 cards. This is really config data that it needs to get at load time. Implemented this in cx25840 and ivtv.

* V4L/DVB: v4l2: Add new control handling frameworkHans Verkuil2010-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new framework to handle controls which makes life for driver developers much easier. Note that this patch moves some of the control support that used to be in v4l2-common.c to v4l2-ctrls.c. The tables were copied unchanged. The body of v4l2_ctrl_query_fill() was copied to a new v4l2_ctrl_fill() function in v4l2-ctrls.c. This new function doesn't use the v4l2_queryctrl struct anymore, which makes it more general. The remainder of v4l2-ctrls.c is all new. Highlights include: - No need to implement VIDIOC_QUERYCTRL, QUERYMENU, S_CTRL, G_CTRL, S_EXT_CTRLS, G_EXT_CTRLS or TRY_EXT_CTRLS in either bridge drivers or subdevs. New wrapper functions are provided that can just be plugged in. Once everything has been converted these wrapper functions can be removed as well. - When subdevices are added their controls can be automatically merged with the bridge driver's controls. - Most drivers just need to implement s_ctrl to set the controls. The framework handles the locking and tries to be as 'atomic' as possible. - Ready for the subdev device nodes: the same mechanism applies to subdevs and their device nodes as well. Sub-device drivers can make controls local, preventing them from being merged with bridge drivers. - Takes care of backwards compatibility handling of VIDIOC_S_CTRL and VIDIOC_G_CTRL. Handling of V4L2_CID_PRIVATE_BASE is fully transparent. CTRL_CLASS controls are automatically added.

* V4L/DVB: cx23885: Move AV Core irq handling to a work handlerAndy Walls2010-08-08
| | | | | | | | | | Interrupts from the AV Core are best handled by a workqueue handler since many I2C transactions are required to service the AV Core interrupt.

* V4L/DVB: cx23885: Protect PCI interrupt mask manipulations with a spinlockAndy Walls2010-08-08
| | | | | | | | | | This patch encapsulates access to the PCI_INT_MSK register and dev->pci_irqmask variable and protects them with a spinlock. This is needed because both the hard IRQ handler and a workhandler will need to manipulate the mask to disable the AV_CORE interrupt.

| | | | | | | | | | | | | | | | Add initial IR Rx support using the intergrated IR controller in the A/V core of the CX23885 bridge chip. This initial support is flawed in that I2C transactions should not be performed in a hard irq context. That will be fixed in a follow on patch. The TeVii S470 support is reported to generate perptual interrupts that renders a user' system nearly unusable. The TeVii S470 IR will be disabled by default in a follow on patch.

* V4L/DVB: cx25840: Add support for CX2388[57] A/V core integrated IR controllersAndy Walls2010-08-08
| | | | | | | | | | | | | | | | | | | | | | | | This patch is primarily a port of the integrated IR controller code in cx23885/cx23888-ir.c. Right now, only the CX2388[57] AV core will really try to set up IR. This IR support, by design, still requires the bridge driver to do final IO pin mux configuration and setup of the IR controller parameters. For the CX2388[578] chips, enabling the AV Core for IR also starts sending Audio and Video interrupts to the bridge driver. For CX2388[578] chips audio and video interrupts are ignored and acknowledged when they happen. IR interrupt handling and status logging is exluded for the CX23888 which does not have an IR controller on the AV core. Note that experimentation reveals that the IR irq enables on the CX23885 have an inverted logic sense. The CX23887 likely suffers from the same quirk. For these chips, those irq enable bits are handled as interrupt disables. Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | The CX2584x and related cores are multifunction subdevices with a number of internal blocks that act as interrupt sources. Move the v4L2_subdev interrupt_service_routine callback from v4l_subdev_ir_ops to v4l2_subdev_core_ops, as the video and audio blocks of a CX2584x and related cores can generate interrupts along with the IR block.
