The lirc user interface exists as a raw decoder, which does not make much sense for transmit-only devices. In addition, we want to have lirc char devices for devices which do not use raw IR, i.e. scancode only devices. Note that rc-code, lirc_dev, ir-lirc-codec are now calling functions of each other, so they've been merged into one module rc-core to avoid circular dependencies. Since ir-lirc-codec no longer exists as separate codec module, there is no need for RC_DRIVER_IR_RAW_TX type drivers to call ir_raw_event_register(). Signed-off-by:

This introduces a new lirc mode: scancode. Any device which can send raw IR can now also send scancodes. int main() { int mode, fd = open("/dev/lirc0", O_RDWR); mode = LIRC_MODE_SCANCODE; if (ioctl(fd, LIRC_SET_SEND_MODE, &mode)) { // kernel too old or lirc does not support transmit } struct lirc_scancode scancode = { .scancode = 0x1e3d, .rc_proto = RC_PROTO_RC5, }; write(fd, &scancode, sizeof(scancode)); close(fd); } The other fields of lirc_scancode must be set to 0. Note that toggle (rc5, rc6) and repeats (nec) are not implemented. Nor is there a method for holding down a key for a period. Signed-off-by: -

LIRCCODE is a lirc mode where a driver produces driver-dependent codes for receive and transmit. No driver uses this any more. The LIRC_GET_LENGTH ioctl was used for this mode only. Signed-off-by:

The ir-kbd-i2c driver behaves like the lirc_zilog driver, except it can send raw IR and receives scancodes rather than lirccodes. The lirc_zilog driver only polls if the lirc chardev is opened; similarly the ir-kbd-i2c driver only polls if the corresponding input device is opened, or the lirc device. Polling is disabled during IR transmission through the mutex. The polling period is 402ms in the ir-kdb-i2c driver, and 260ms in the lirc_zilog driver. Signed-off-by:

This is a fix for commit 329d88da ("[media] media: i2c: Don't export ir-kbd-i2c module alias") that stopped the module from being loaded automagically. The problems described only affect the HD-PVR, so it should not affect other hardware; also if the module happens to be loaded, the i2c IR part of the HD-PVR will be enabled anyway.

This code implements the transmitter which is currently implemented in the staging lirc_zilog driver. The new code does not need a signal database, iow. the haup-ir-blaster.bin firmware file is no longer needed, and the driver does not know anything about the keycodes in that file. Instead, the new driver can send raw IR, but the hardware is limited to few different lengths of pulse and spaces, so it is best to use generated IR rather than recorded IR. Signed-off-by:

These two devices ids are really just one device with multiple addresses. Probing becomes much simpler if we simply fold this into one i2c device with two address. Note that this breaks the lirc_zilog driver, however we will teach ir-kbd-i2c to do what lirc_zilog does in a later commit. Signed-off-by:

With the parent set for the rc device, the messages clearly state that it is attached via i2c. The additional printk is unnecessary. These are the old messages: rc rc1: i2c IR (Hauppauge WinTV PVR-150 as /devices/virtual/rc/rc1 ir-kbd-i2c: i2c IR (Hauppauge WinTV PVR-150 detected at i2c-10/10-0071/ir0 [ivtv i2c driver #0] Now we simply get: rc rc1: Hauppauge WinTV PVR-150 as /devices/pci0000:00/0000:00:1e.0/0000:02:00.0/i2c-10/10-0071/rc/rc1 Note that we no longer copy the name. I've checked all call sites to verfiy this is not a problem. Signed-off-by:

When iterating through all endpoints using of_graph_get_next_endpoint(), the refcount of the returned endpoint node is incremented and the refcount of the node which is passed as previous endpoint is decremented. So the caller doesn't need to call of_node_put() for each iterated node except for error exit paths. Otherwise we get "OF: ERROR: Bad of_node_put() on ..." messages.

Currently a user can pass in an unsanitized slot number which will lead to and out of range index into ca->slot_info. Fix this by checking that the slot number is no more than the allowed maximum number of slots. Seems that this bug has been in the driver forever.

This change makes sure that demod frontends are always detached whenever a tuner frontend attach failed. Achieve this by moving the detach-on- failure logic at the end of dvb_input_attach(), and adding a goto to this block on every tuner attach failure case, so if an error occurs, there are no stray attached frontends left. As a side effect, this removes some duplicated code. Signed-off-by:
