2012-09-15[media] ir-rx51: Adjust dependenciesTimo Kokkonen
Although this kind of IR diode circuitry is known to exist only in N900 hardware, nothing prevents making similar circuitry on any OMAP based board. The MACH_NOKIA_RX51 dependency is thus not something we want to be there. Also, this should depend on LIRC as it is a LIRC driver.

2012-09-14[media] rc: ite-cir: Initialise ite_dev::rdev earlierBen Hutchings
ite_dev::rdev is currently initialised in ite_probe() after rc_register_device() returns. If a newly registered device is opened quickly enough, we may enable interrupts and try to use ite_dev::rdev before it has been initialised. Move it up to the earliest point we can, right after calling rc_allocate_device().

2012-08-13[media] rc-core: move timeout and checks to lircDavid Härdeman
The lirc TX functionality expects the process which writes (TX) data to the lirc dev to sleep until the actual data has been transmitted by the hardware. Since the same timeout calculation is duplicated in more than one driver (and would have to be duplicated in even more drivers as they gain TX support), it makes sense to move this timeout calculation to the lirc layer instead. At the same time, centralize some of the sanity checks.

2012-08-13[media] media: rc: Introduce RX51 IR transmitter driverTimo Kokkonen
This is the driver for the IR transmitter diode found on the Nokia N900 (also known as RX51) device. The driver is mostly the same as found in the original 2.6.28 based kernel that comes with the device. The following modifications have been made compared to the original driver version: - Adopt to the changes that has happen in the kernel during the past five years, such as the change in the include paths - The OMAP DM-timers require much more care nowadays. The timers need to be enabled and disabled or otherwise many actions fail. Timers must not be freed without first stopping them or otherwise the timer cannot be requested again. The code has been tested with sending IR codes with N900 device running Debian userland. The device receiving the codes was Anysee DVB-C USB receiver.

The iguanair hardware advertises an interval of 10 which just not enough; with 100 URBs per second and at most 7 edges per URB, we handle at most 700 edges per second. The remote generates about 900.

2012-07-30[media] Avoid sysfs oops when an rc_dev's raw device is absentDouglas Bagnall
For some reason, when the lirc daemon learns that a usb remote control has been unplugged, it wants to read the sysfs attributes of the disappearing device. This is useful for uncovering transient inconsistencies, but less so for keeping the system running when such inconsistencies exist. Under some circumstances (like every time I unplug my dvb stick from my laptop), lirc catches an rc_dev whose raw event handler has been removed (presumably by ir_raw_event_unregister), and proceeds to interrogate the raw protocols supported by the NULL pointer. This patch avoids the NULL dereference, and ignores the issue of how this state of affairs came about in the first place. Version 2 incorporates changes recommended by Mauro Carvalho Chehab (-ENODEV instead of -EINVAL, and a signed-off-by).
