* V4L/DVB: IR: add helper function for hardware with small o/b bufferMaxim Levitsky2010-08-08
| | | | | | | | | | | | | | | | | Some ir input devices have small buffer, and interrupt the host each time it is full (or half full) Add a helper that automaticly handles timeouts, and also automaticly merges samples of same time (space-space) Such samples might be placed by hardware because size of sample in the buffer is small (a byte for example). Also remove constness from ir_dev_props, because it now contains timeout settings that driver might want to change Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Acked-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: IR: replace workqueue with kthreadMaxim Levitsky2010-08-08
| | | | | | | | | | | | | | It is perfectly possible to have ir_raw_event_work running concurently on two cpus, thus we must protect it from that situation. This stems from the fact that if hardware sends short packets of samples we might end up queueing the work item more times that nessesary. Such job isn't well suited for a workqueue, so use a kernel thread. Signed-off-by: Maxim Levitsky <maximlevitsky@gmail.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* V4L/DVB: staging/lirc: port lirc_streamzap to ir-coreJarod Wilson2010-08-08
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This ports lirc_streamzap.c over to ir-core in-place, to be followed by a patch moving the driver over to drivers/media/IR/streamzap.c and enabling the proper Kconfig bits. Presently, the in-kernel keymap doesn't work, as the stock Streamzap remote uses an RC-5-like, but not-quite-RC-5 protocol, which the in-kernel RC-5 decoder doesn't cope with. The remote can be used right now with the lirc bridge driver though, and other remotes (at least an RC-6(A) MCE remote) work perfectly with the driver. I'll take a look at making the existing RC-5 decoder cope with this odd duck, possibly implement another standalone decoder engine, or just throw up my hands and say "meh, use lirc"... But the driver itself should be perfectly sound. Remaining items on the streamzap TODO list: - add LIRC_SET_REC_TIMEOUT-alike support - add LIRC_GET_M{AX,IN}_TIMEOUT-alike support - add LIRC_GET_REC_RESOLUTION-alike support All of the above should be trivial to add. There are patches pending to add this support to ir-core from Maxim Levitsky, and I'll take care of these once his patches get integrated. None of them are currently essential though.

* 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. The AV_CORE PCI interrupt is disabled by the IRQ handler and reenabled when the work handler is finished.

* 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.

* V4L/DVB: cx23885: Add preliminary IR Rx support for the HVR-1250 and TeVii S470Andy Walls2010-08-08
| | | | | | | | | | | | | | | | 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>
* V4L/DVB: v4l2_subdev: Move interrupt_service_routine ptr to v4l2_subdev_core_opsAndy Walls2010-08-08
| | | | | | | | | | | | | 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. This change also makes sense for other subdev's that generate interrupts and do not have an IR block.

| | | | | | | | | | | | | | | inversion There is a distinction on IR Tx for the CX2388[578] chips of carrier sense inversion (space is a carrier burst and mark is no burst) and I/O pin level inversion (0 is high output level, 1 is low output level). Allow the caller to set these parameters distinctly as v4l2_subdevice IR parameters. This permits the IR device to be configured and enabled without the IR Tx LED being on during idle/space time due to an external hardware level inversion Signed-off-by: Andy Walls <awalls@md.metrocast.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
