* [media] omap3isp: Fix build error in ispccdc.cJoerg Roedel2011-09-211-0/+1
| | | | | | | | | | | | The following build error occurs with 3.1-rc5: CC drivers/media/video/omap3isp/ispccdc.o This patch adds the missing 'linux/slab.h' include to fix the problem.

* [media] uvcvideo: Fix crash when linking entitiesLaurent Pinchart2011-09-211-1/+1
| | | | | | | | | | The uvc_mc_register_entity() function wrongfully selects the media_entity associated with a UVC entity when creating links. This results in access to uninitialized media_entity structures and can hit a BUG_ON statement in media_entity_create_link(). Fix it.

| | | | | | | | | | | | | | | | If the bus has been reset on resume, set the alternate setting to 0. This should be the default value, but some devices crash or otherwise misbehave if they don't receive a SET_INTERFACE request before any other video control request.

* [media] vp7045: fix buffer setupFlorian Mickler2011-09-111-22/+4
| | | | | | | | | | | | | | | | | | | | dvb_usb_device_init calls the frontend_attach method of this driver which uses vp7045_usb_ob. In order to have a buffer ready in vp7045_usb_op, it has to be allocated before that happens. Luckily we can use the whole private data as the buffer as it gets separately allocated on the heap via kzalloc in dvb_usb_device_init and is thus apt for use via usb_control_msg. This fixes a BUG: unable to handle kernel paging request at 0000000000001e78 reported by Tino Keitel and diagnosed by Dan Carpenter.

* [media] nuvoton-cir: simplify raw IR sample handlingJarod Wilson2011-09-112-38/+8
| | | | | | | | | | | | | | | | | The nuvoton-cir driver was storing up consecutive pulse-pulse and space-space samples internally, for no good reason, since ir_raw_event_store_with_filter() already merges back to back like samples types for us. This should also fix a regression introduced late in 3.0 that related to a timeout change, which actually becomes correct when coupled with this change. Tested with RC6 and RC5 on my own nuvoton-cir hardware atop vanilla 3.0.0, after verifying quirky behavior in 3.0 due to the timeout change.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer the needed packet size. Yet, it is better than nothing. Rewrite the code in order to change the default to 752 for em2884 and newer chips and provide a better way to handle per-chipset specifics. For em2874, the current default should be enough, as the only em2874 board is currently a 1-seg ISDB-T board, so, it needs only a limited amount of bandwidth.

| * [media] tda18271c2dd: Fix saw filter configuration for DVB-C @6MHzMauro Carvalho Chehab2011-07-281-1/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the driver assumes that all QAM carriers are spaced with 8MHz. This is wrong, and may decrease QoS on Countries like Brazil, that have DVB-C carriers with 6MHz-spaced. Fortunately, both ITU-T J-83 and EN 300 429 specifies a way to associate the symbol rate with the bandwidth needed for it. For ITU-T J-83 2007 annex A, the maximum symbol rate for 6 MHz is: 6 MHz / 1.15 = 5217391 Bauds For ITU-T J-83 2007 annex C, the maximum symbol rate for 6 MHz is: 6 MHz / 1.13 = 5309735 Bauds. As this tuner is currently used only for DRX-K, and it is currently hard-coded to annex A, I've opted to use the roll-off factor of 0.15, instead of 0.13. If we ever support annex C, the better would be to add a DVB S2API call to allow changing between Annex A and C, and add the 0.13 roll-off factor to it. This code is currently being used on other frontends, so I think we should later add a core function with this code, to warrant that it will be properly implemented everywhere.

| * [media] au8522: set signal field to 100% when signal presentDevin Heitmueller2011-07-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | The signal state field in G_TUNER is typically scaled from 0-100%. Since we don't know the signal level, we really would prefer the field to contain 100% than 1/256, which in many utilities (such as v4l2-ctl) rounds to 0% even when a signal is actually present. This patch makes the behavior consistent with other drivers. Signed-off-by: Devin Heitmueller <dheitmueller@kernellabs.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On platforms that have CONFIG_HZ set to 100, the power ramp time effectively ends up being 10ms. However, on those that have a higher CONFIG_HZ, the time ends up *actually* being 5ms, which doesn't allow enough time for the hardware to be fully powered up before attempting to address it via i2c. Change the constant to 10ms, which is long enough for the hardware to power up, and won't really be anymore time than it was previously on platforms with CONFIG_HZ being 100. Credit goes to Mauro Carvalho Chehab and Gerd Hoffmann who previously investigated this issue. Tested with the Hauppauge USBLive 2, with which the problem was readily reproducible after setting CONFIG_HZ to 1000.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following patch addresses the regression introduced in the cx231xx driver which stopped the Hauppauge USBLive2 from working. Confirmed working by both myself and the user who reported the issue on the KernelLabs blog (Robert DeLuca). At some point during refactoring of the cx231xx driver, the USBLive 2 device became broken. This patch results in the device working again. Thanks to Robert DeLuca for sponsoring this work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The search for matching extension units fails to take account of the current chain. In the case where you have two distinct video chains, both containing an XU with the same GUID but different unit ids, you will be unable to perform a mapping on the second chain because entity on the first chain will always be found first Fix this by only searching the current chain when performing a control mapping. This is analogous to the search used by uvc_find_control(), and is the correct behaviour.
