2017-01-30[media] staging: lirc_imon: port remaining usb ids to imon and removeSean Young
The staging lirc_imon driver contains 4 usb ids. Two of those have a VFD and two don't. The VFD code is exactly the same in the mainline imon driver, so that part is easily ported. The staging driver produces raw IR rather than scancodes for the four devices, so I've ported the raw IR code from staging to mainline imon. Now that mainline imon can handle these four devices, lirc_imon is no longer needed. Compile tested only.

2017-01-30[media] rc-main: assign driver type during allocationAndi Shyti
The driver type can be assigned immediately when an RC device requests to the framework to allocate the device. This is an 'enum rc_driver_type' data type and specifies whether the device is a raw receiver or scancode receiver. The type will be given as parameter to the rc_allocate_device device. Change accordingly all the drivers calling rc_allocate_device() so that the device type is specified during the rc device allocation. Whenever the device type is not specified, it will be set as RC_DRIVER_SCANCODE which was the default '0' value.

2016-10-24[media] imon: use complete() instead of complete_all()Daniel Wagner
There is only one waiter for the completion, therefore there is no need to use complete_all(). Let's make that clear by using complete() instead of complete_all(). While we are at it, we do a small optimization with the reinitialization of the completion before we use it. The usage pattern of the completion is: waiter context waker context send_packet() init_completion() usb_submit_urb() wait_for_completion_interruptible() usb_tx_callback() complete() imon_disonnect() complete() Signed-off-by: Daniel Wagner <daniel.wagner@bmw-carit.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
2016-10-21[media] rc: don't break long linesMauro Carvalho Chehab
Due to the 80-cols restrictions, and latter due to checkpatch warnings, several strings were broken into multiple lines. This is not considered a good practice anymore, as it makes harder to grep for strings at the source code. As we're right now fixing other drivers due to KERN_CONT, we need to be able to identify what printk strings don't end with a "\n". It is a way easier to detect those if we don't break long lines. So, join those continuation lines. The patch was generated via the script below, and manually adjusted if needed. </script> use Text::Tabs; while (<>) { if ($next ne "") { $c=$_; if ($c =~ /^\s+\"(.*)/) { $c2=$1; $next =~ s/\"\n$//; $n = expand($next); $funpos = index($n, '('); $pos = index($c2, '",'); if ($funpos && $pos > 0) { $s1 = substr $c2, 0, $pos + 2; $s2 = ' ' x ($funpos + 1) . substr $c2, $pos + 2; $s2 =~ s/^\s+//; $s2 = ' ' x ($funpos + 1) . $s2 if ($s2 ne ""); print unexpand("$next$s1\n"); print unexpand("$s2\n") if ($s2 ne ""); } else { print "$next$c2\n"; } $next=""; next; } else { print $next; } $next=""; } else { if (m/\"$/) { if (!m/\\n\"$/) { $next=$_; next; } } } print $_; } </script> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>

2014-07-25[media] rc-core: remove protocol arraysDavid Härdeman
The basic API of rc-core used to be: dev = rc_allocate_device(); dev->x = a; dev->y = b; dev->z = c; rc_register_device(); which is a pretty common pattern in the kernel, after the introduction of protocol arrays the API looks something like: dev = rc_allocate_device(); dev->x = a; rc_set_allowed_protocols(dev, RC_BIT_X); dev->z = c; rc_register_device(); There's no real need for the protocols to be an array, so change it back to be consistent (and in preparation for the following patches).

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.

2012-10-27[media] rc-core: add separate defines for protocol bitmaps and numbersDavid Härdeman
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.

2012-01-26[media] imon: don't wedge hardware after early callbacksJarod Wilson
This patch is just a minor update to one titled "imon: Input from ffdc device type ignored" from Corinna Vinschen. An earlier patch to prevent an oops when we got early callbacks also has the nasty side-effect of wedging imon hardware, as we don't acknowledge the urb. Rework the check slightly here to bypass processing the packet, as the driver isn't yet fully initialized, but still acknowlege the urb and submit a new rx_urb. Do this for both interfaces -- irrelevant for ffdc hardware, but relevant for newer hardware, though newer hardware doesn't spew the constant stream of data as soon as the hardware is initialized like the older ffdc devices, so they'd be less likely to trigger this anyway... Tested with both an ffdc device and an 0042 device.

2011-09-21[media] imon: don't parse scancodes until intf configuredJarod Wilson
The imon devices have either 1 or 2 usb interfaces on them, each wired up to its own urb callback. The interface 0 urb callback is wired up before the imon context's rc_dev pointer is filled in, which is necessary for imon 0xffdc device auto-detection to work properly, but we need to make sure we don't actually run the callback routines until we've entirely filled in the necessary bits for each given interface, lest we wind up oopsing. Technically, any imon device could have hit this, but the issue is exacerbated on the 0xffdc devices, which send a constant stream of interrupts, even when they have no valid key data.

Unknown devices default to the imon native protocol, but might actually be rc6, so we should set the driver up such that the user can load the rc6 keytable from userspace and still have a working device ahead of its config byte being added to the driver.
