* Drivers: media: remove __dev* attributes.Greg Kroah-Hartman2013-01-0313-36/+36
| | | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

| * [media] winbond-cir: add carrier detectionSean Young2012-11-211-5/+75
| | | | | | | | | | | | | | | | | | | | The winbond hardware has a counter for leading edges, which increases as they are received. As we read raw IR from a fifo in an interrupt handler, we cannot correlate them to specific IR pulses so we simply count all pulses and edges until we go idle and disable the receiver.

| | | | | | | | | | | | | | | | | | | | The receiver is never disabled by idle mode since rxstate never gets set to RXSTATE_ACTIVE, so we keep on getting interrupts after the first IR activity ends.

| * [media] ene-ir: Fix cleanup on probe failureMatthijs Kooijman2012-10-281-16/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes the cleanup on probe failure more consistent with other drivers. This is similar to what commit f27b853ea24a9b70585f9251384d97929e6551c3 ("[media] rc: Fix invalid free_region and/or free_irq on probe failure") did for some other drivers. In addition to making the cleanup more consistent, this also fixes a case where (on a ene_hw_detect failure) free_region would be called on a region that was not requested yet. This last problem was probably introduced by the moving of code in commit b31b021988fed9e3741a46918f14ba9b063811db ("[media] ene_ir: Fix driver initialisation") and commit 9ef449c6b31bb6a8e6dedc24de475a3b8c79be20 ("[media] rc: Postpone ISR registration").

| * [media] rc-core: add separate defines for protocol bitmaps and numbersDavid Härdeman2012-10-2726-89/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The RC_TYPE_* defines are currently used both where a single protocol is expected and where a bitmap of protocols is expected. Functions like rc_keydown() and functions which add/remove entries to the keytable want a single protocol. Future userspace APIs would also benefit from numeric protocols (rather than bitmap ones). Keytables are smaller if they can use a small(ish) integer rather than a bitmap. Other functions or struct members (e.g. allowed_protos, enabled_protocols, etc) accept multiple protocols and need a bitmap. Using different types reduces the risk of programmer error. Using a protocol enum whereever possible also makes for a more future-proof user-space API as we don't need to worry about a sufficient number of bits being available (e.g. in structs used for ioctl() calls). The use of both a number and a corresponding bit is dalso one in e.g. the input subsystem as well (see all the references to set/clear bit when changing keytables for example). This patch separate the different usages in preparation for upcoming patches. Where a single protocol is expected, enum rc_type is used; where one or more protocol(s) are expected, something like u64 is used. The patch has been rewritten so that the format of the sysfs "protocols" file is no longer altered (at the loss of some detail). The file itself should probably be deprecated in the future though.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Pioneer CU-700 remote causes receiver overflows if you hold down any button. The remote does not send NEC IR repeats, it repeats the entire NEC code after 20ms. 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.
